The Battery Tender 022-1005-DL-WH is a 12-volt charger and maintainer that lets you choose 8 Amp for faster recovery of a deeply discharged battery, or 2 Amp if you prefer a gentler rate during storage. The manufacturer presents it as the upgraded replacement for the legacy 022-0337, adding IP65 weather resistance and lithium multi-chemistry support. Its ISM algorithm moves to float maintenance automatically once the battery is full, supplying only the micro-current needed to offset self-discharge.
Compared with a basic trickle charger, the temperature compensation works automatically with no manual adjustment or settings required. That matters for a battery in an unheated garage or a seasonal vehicle. Owners on user forums commonly recommend a permanent ring terminal connection over repeated clamp hookups, and note that the eyelet needs a solid bolt-down point. The charger also includes a 6 AMP power supply and supports batteries from 20Ah to 150Ah at 12V.
Fitment is battery-based rather than vehicle-specific, and the manufacturer notes it is a 12V-only charger, not compatible with 6V or 24V systems. The included cable is a ring terminal and alligator clip combo, and the manufacturer says if the fuse ever blows, replace it only with a 15 AMP ATO/ATC blade fuse.
No. The manufacturer states this is a 12V-only charger and is not compatible with 6V or 24V systems.
The manufacturer says to replace it only with a 15 Amp ATO/ATC blade fuse. A lower rating may blow prematurely, and a higher rating risks damaging the charger or wiring.
Per the manufacturer, the charger steps down to float maintenance automatically at the correct threshold in either output mode, so the battery is not overcharged and the unit can stay connected once full.
The manufacturer rates it IP65 and states it can be permanently mounted in outdoor locations, engine compartments, and semi-exposed storage areas.
The manufacturer describes the 022-1005 as the updated version of the 022-0337 with the same dual-rate concept, plus IP65 weather resistance and lithium multi-chemistry support.
For a permanent setup, the manufacturer's install guide recommends ring terminals, which you slide over each battery post under the existing clamp and tighten, using a wrench or socket of about 10 mm. The manufacturer advises a ring terminal harness for any vehicle that will stay connected more than 48 hours. Owners on user forums suggest routing the lead to a protected spot such as under the hood or behind a cover, then fusing the positive side close to the battery. Use alligator clips for one-time charging, and check that the ring terminal sits flush against the post with no wobble before powering up.
