It's a legitimate engineering solution to a problem every track driver, weekend warrior, and daily driver has run into at some point \u2014 a dead battery at the worst possible time.<\/p>\n\n      <p>This guide covers how the RE-START system actually works at a mechanical level, when that function saves you, which group sizes are available, how to pick the right amp-hour rating for your application, and what the BMS does beyond just jump starting.<\/p>\n\n      <div class=\"callout\">\n        <p><strong>Shop Antigravity RE-START Batteries at Track Ready Products:<\/strong> We carry the full automotive RE-START lineup in H5, H6, H7, H8, Group 24, Group 27, Group 35, and more. <a href=\"https:\/\/www.trackreadyproducts.com\/antigravity-batteries-m-59.html\">Browse Antigravity products \u2192<\/a><\/p>\n      <\/div>\n\n      <!-- Section 1 -->\n      <h2 id=\"how-restart-works\">How the RE-START System Actually Works<\/h2>\n\n      <p>The RE-START function is built into the Battery Management System that lives inside every Antigravity automotive lithium battery. It's not a separate add-on or an external device \u2014 it's part of the battery itself. Here's what happens step by step when the system engages.<\/p>\n\n      <h3>Continuous Voltage Monitoring<\/h3>\n      <p>The BMS monitors the battery's voltage in real time, all the time \u2014 whether the vehicle is running, parked, or sitting in storage. It's watching for the voltage curve that indicates over-discharge is approaching: the point where a lithium cell starts heading toward damage territory and where a lead-acid battery would simply die.<\/p>\n\n      <h3>Sleep Mode Activation<\/h3>\n      <p>Just before the battery hits a critically low voltage \u2014 the threshold where a conventional battery would be dead and unrecoverable without external charging \u2014 the BMS pulls the battery into a protected sleep state. It disconnects the main circuit to stop the drain. Critically, it does this while there's still enough charge in reserve to produce a high-current starting burst.<\/p>\n\n      <h3>The Reserve Start Pulse<\/h3>\n      <p>That reserved energy isn't just sitting there passively. When you press the wireless keyfob button, the BMS reconnects the circuit and delivers a high-current discharge pulse to the starter motor \u2014 enough to crank the engine and get you going. The keyfob range is sufficient to activate from inside the car without opening the hood. There's also a manual button on top of the battery itself as a backup if the keyfob isn't handy.<\/p>\n\n      <h3>After RE-START<\/h3>\n      <p>Once the engine starts, the alternator takes over and begins recharging the battery normally. The BMS returns to its active monitoring state. The RE-START function resets and is available again once the battery has been sufficiently recharged. It is not a repeatable emergency drain \u2014 if you RE-START, drive away, and then immediately kill the engine without giving the alternator time to recharge, the reserve won't be available again immediately.<\/p>\n\n      <div class=\"callout\">\n        <p><strong>Important distinction:<\/strong> RE-START is not designed for a battery that's been sitting dead for days or weeks. It's designed for acute discharge events \u2014 lights left on for a few hours, a short parasitic drain overnight, brief electronics use with the engine off. A deeply discharged battery needs a proper lithium-compatible charger before RE-START will work again.<\/p>\n      <\/div>\n\n      <div class=\"stat-grid\">\n        <div class=\"stat-block\">\n          <span class=\"num\">70%<\/span>\n          <span class=\"label\">Lighter than lead-acid equivalent<\/span>\n        <\/div>\n        <div class=\"stat-block\">\n          <span class=\"num\">3\u00d7<\/span>\n          <span class=\"label\">Cranking amps vs same-size lead-acid<\/span>\n        <\/div>\n        <div class=\"stat-block\">\n          <span class=\"num\">900hp<\/span>\n          <span class=\"label\">Max engine displacement RE-START batteries can handle<\/span>\n        <\/div>\n        <div class=\"stat-block\">\n          <span class=\"num\">7\u20139yr<\/span>\n          <span class=\"label\">Expected battery lifespan with BMS<\/span>\n        <\/div>\n      <\/div>\n\n      <!-- Section 2 -->\n      <h2 id=\"when-you-need-it\">When You Actually Need RE-START<\/h2>\n\n      <p>It helps to think through the real scenarios where this matters. RE-START isn't a gimmick \u2014 it targets a specific failure mode that happens far more often than most drivers account for.<\/p>\n\n      <h3>Lights Left On at the Track<\/h3>\n      <p>At a track day or HPDE event, you run a session, pull into the paddock, kill the engine, and start reviewing data or talking to your instructor. The headlights are on because you were running in grid or because your car's DRLs don't shut off with the ignition. Two hours later, dead battery. With RE-START, the BMS catches the discharge before it's fatal, and you press the keyfob instead of hunting for jumper cables in a crowded paddock.<\/p>\n\n      <h3>Parasitic Drain from Electronics<\/h3>\n      <p>Modern performance cars carry significant parasitic loads \u2014 ECU memory, alarm systems, data loggers, Bluetooth modules, dash cameras, phone chargers left plugged in. On a car with a standard lead-acid battery these drains are managed because lead-acid tolerates a slower discharge curve. Lithium batteries, without BMS protection, can be damaged by this kind of sustained low-level drain. The RE-START BMS handles it by cutting off before damage occurs and preserving enough for one more start.<\/p>\n\n      <h3>Extended Paddock Parking<\/h3>\n      <p>For multi-day events \u2014 a weekend endurance race, an out-of-town track weekend \u2014 the car sits overnight in the paddock. Climate control, security systems, and ECU keep-alive circuits run the whole time. A stock lead-acid battery in marginal condition might not make it. An Antigravity RE-START battery holds charge significantly better due to lithium's lower self-discharge rate, and if it does dip too low, RE-START is there.<\/p>\n\n      <h3>Storage Between Events<\/h3>\n      <p>A dedicated track car that sits between events is one of the highest-risk use cases for any battery. Lithium chemistry handles extended storage far better than lead-acid \u2014 much lower self-discharge rate means it holds charge for weeks or months without a tender. But if a parasitic drain does pull it down, RE-START catches it.<\/p>\n\n      <h3>When RE-START Won't Save You<\/h3>\n      <p>RE-START is not a substitute for a healthy charging system. If your alternator is failing, your voltage regulator is spiking, or your battery has been over-discharged below the point where the BMS can still hold a reserve, RE-START won't help. It also won't help if the battery has been deeply discharged over an extended period \u2014 in that case, a lithium-compatible charger is the solution, not the keyfob.<\/p>\n\n      <!-- Section 3 -->\n      <h2 id=\"bms\">The Full BMS: What Else It Does<\/h2>\n\n      <p>RE-START is the most visible feature of the Antigravity automotive battery, but the BMS that powers it also does a lot of work that you'll never notice because it's preventing failures rather than recovering from them.<\/p>\n\n      <h3>Over-Discharge Protection<\/h3>\n      <p>Lithium cells are damaged by deep discharge in a way that lead-acid is not. A lead-acid battery can be brought back from a dead state repeatedly \u2014 it just loses capacity over time. A lithium cell taken below its minimum voltage threshold can be permanently damaged in a single event. The BMS's low-voltage cutoff prevents this from ever happening during normal use.<\/p>\n\n      <h3>Over-Charge Protection<\/h3>\n      <p>On the other side, lithium cells are also sensitive to over-voltage. A failing voltage regulator that spikes above the battery's maximum charge voltage will damage lithium cells. The BMS monitors for over-charge conditions and cuts off the circuit before damage occurs. This is the most common cause of lithium battery warranty claims \u2014 a bad regulator pushing too much voltage \u2014 and the BMS is the only thing that can prevent it.<\/p>\n\n      <h3>Cell Balancing<\/h3>\n      <p>A lithium battery is made up of multiple cells. Over time, those cells can drift apart in their state of charge, with some cells working harder than others. The BMS continuously balances the cells, keeping them in sync. This is what enables Antigravity to rate expected lifespan at 7 to 9 years \u2014 the BMS is actively extending cell life throughout the battery's service life.<\/p>\n\n      <h3>Short-Circuit and Thermal Protection<\/h3>\n      <p>The BMS includes short-circuit protection that cuts the circuit instantly if an abnormal load is detected, and thermal protection that monitors cell temperature and limits charge\/discharge if the battery gets too hot. Both protect the battery and the vehicle from the kind of failure modes that make lithium batteries in consumer electronics a concern \u2014 but that are essentially non-issues in a properly BMS-managed automotive application.<\/p>\n\n      <!-- Section 4 -->\n      <h2 id=\"group-sizes\">Available Group Sizes and Specs<\/h2>\n\n      <p>Antigravity RE-START automotive batteries come in exact OEM group sizes \u2014 they drop into the factory battery tray without modifications.

That 25 to 55 lb reduction comes out of a fixed location, almost always at the front of the engine bay, which affects weight distribution and front end feel measurably on a prepared car.<\/p>\n\n      <!-- Section 5 -->\n      <h2 id=\"amp-hours\">Choosing the Right Amp-Hour Rating<\/h2>\n\n      <p>Within most group sizes, Antigravity offers multiple amp-hour options. This is where most buyers get stuck. Here's how to think through it.<\/p>\n\n      <h3>Higher AH = More Reserve Capacity and More Weight<\/h3>\n      <p>A 60Ah H6 battery weighs more than a 24Ah H6 battery and costs more. The tradeoff is reserve capacity \u2014 the amount of energy available to run electronics, ECU keep-alive circuits, and other loads with the engine off before the battery starts running low. For a daily driver or a car with significant electronics, more amp-hours is the right call. For a stripped track-only car where the battery does nothing but start the engine, a 24Ah model is lighter and still has plenty of cranking power.<\/p>\n\n      <h3>Race-Only Track Cars<\/h3>\n      <p>Antigravity explicitly offers 24Ah versions of the H6 and other sizes for race use only \u2014 cars that don't sit overnight, don't have accessories running with the engine off, and where the priority is minimum weight. These batteries still produce 1000 cranking amps, which is more than enough for any normally aspirated or forced-induction race engine. If your car lives at the track and goes back on a trailer, 24Ah is worth considering.<\/p>\n\n      <h3>Street\/Track Dual-Use Cars<\/h3>\n      <p>For a car that does track days but also drives to and from events, 40Ah in the H6 or H7 is the practical sweet spot. Enough reserve capacity to handle normal driving demands, plenty of cranking power, and still substantially lighter than a lead-acid equivalent.<\/p>\n\n      <h3>High-Electronics Vehicles<\/h3>\n      <p>Cars with factory infotainment, multiple camera systems, complex alarm setups, or advanced ECUs \u2014 particularly Ferraris, late-model Porsches with the full PASM suite, and similar \u2014 can benefit from 60Ah or the H8 in 80Ah. Antigravity specifically notes that Ferraris and cars with heavy electronic loads should go H8 to avoid dashboard flags from insufficient amp-hour capacity.<\/p>\n\n      <div class=\"callout-warn\">\n        <p><strong>Ford vehicles with PCM Controlled Smart Charging:<\/strong> Antigravity notes that RE-START batteries are not recommended for Ford vehicles with the factory Smart Charging system, which can conflict with the BMS. Non-RE-START Antigravity models are compatible, or the Ford Forscan tool can be used to switch the charging mode.

No additional modification or custom tray is needed. That said, there are a few things worth doing before and after installation.<\/p>\n\n      <ul class=\"steps\">\n        <li>\n          <span class=\"step-num\">1<\/span>\n          <span class=\"step-text\"><strong>Charge the battery before installation.<\/strong> Antigravity ships batteries partially charged, not at full capacity. Use a lithium-compatible charger (the Antigravity SC-series or a CTEK lithium mode) to bring it to full charge before first install. Do not use a lead-acid charger.<\/span>\n        <\/li>\n        <li>\n          <span class=\"step-num\">2<\/span>\n          <span class=\"step-text\"><strong>Check your voltage regulator and charging system.<\/strong> Use a multimeter to verify your alternator output is within spec \u2014 should be 13.8V to 14.4V at idle. A failing regulator that spikes above 14.4V will trigger the BMS's over-charge protection and, over time, can damage the cells. Fix charging system issues before you install a lithium battery.<\/span>\n        <\/li>\n        <li>\n          <span class=\"step-num\">3<\/span>\n          <span class=\"step-text\"><strong>Pair the keyfobs.<\/strong> Each RE-START battery ships with two wireless keyfobs. Follow the pairing procedure in the included documentation before relying on wireless activation. Keep one keyfob on your keyring and one as a backup in your gear bag.<\/span>\n        <\/li>\n        <li>\n          <span class=\"step-num\">4<\/span>\n          <span class=\"step-text\"><strong>Check for parasitic drains.<\/strong> If your car has known parasitic drain issues \u2014 a clock, alarm, data logger, or ECU keep-alive drawing current continuously \u2014 quantify the draw before installing a lithium battery. The BMS will protect the cells, but a large parasitic drain will trigger sleep mode faster than expected if the car sits for several days.<\/span>\n        <\/li>\n      <\/ul>\n\n      <!-- Section 7 -->\n      <h2 id=\"faq\">Frequently Asked Questions<\/h2>\n\n      <h3>How many times can I use RE-START before I need to recharge?<\/h3>\n      <p>RE-START is a one-use emergency function per discharge event. After using it to start the car, drive long enough for the alternator to recharge the battery before relying on it again. It's not designed for repeated back-to-back starting attempts from a depleted state.<\/p>\n\n      <h3>Can I use RE-START if the battery is completely dead?<\/h3>\n      <p>No. RE-START requires that the BMS was able to enter sleep mode before the battery fully discharged. If the battery was drained past that threshold \u2014 by a very large parasitic load, a failed alternator, or external discharge \u2014 RE-START won't have a reserve to work from. A lithium-compatible charger is needed to recover in that case.<\/p>\n\n      <h3>Does the keyfob work through the car body?<\/h3>\n      <p>Yes. The wireless activation is designed to work from inside the vehicle, through the body panels, without opening the hood. You don't need to be near the battery for it to work.<\/p>\n\n      <h3>Will an Antigravity RE-START battery work with my OEM battery management system?<\/h3>\n      <p>For most vehicles, yes. The one known exception is Ford vehicles with PCM Controlled Smart Charging \u2014 the factory charging system doesn't play well with RE-START models. For all other makes, the battery drops in as an OEM replacement and the BMS handles compatibility internally.<\/p>\n\n      <h3>How do I know which group size my car takes?<\/h3>\n      <p>Your owner's manual lists the battery group size. It's also stamped on a label on your current battery. Antigravity's website has a vehicle fitment lookup tool if you're unsure. If you're still not sure, reach out to us at Track Ready Products and we'll help identify the right model.<\/p>\n\n      <h3>Do I need to do anything special for long-term storage?<\/h3>\n      <p>For storage over 30 days, charge the battery to full before parking the vehicle. If there are significant parasitic drains, disconnect the battery or use a lithium-compatible maintainer on the Antigravity SC-series. The low self-discharge rate of lithium means a fully charged Antigravity battery will hold charge for months without a tender under normal conditions.<\/p>\n\n      <hr class=\"section-rule\">\n\n      <div class=\"cta-block\">\n        <h3>Ready to Make the Switch?<\/h3>\n        <p>Track Ready Products is an authorized Antigravity dealer.
