The Battery Tender 12V selectable charger (MPN 022-0199-DL-WH) is a compact, fully automatic maintainer for 12-volt batteries, built around an ISM microcontroller that adjusts the charge sequence as the battery moves through each stage. Its key feature is a chemistry switch: pressing the SELECT button toggles the charging profile between lead-acid (flooded, AGM, GEL, sealed) and lithium iron phosphate (LiFePO4). One unit can therefore handle a bike still running a conventional battery or one that has been upgraded to lithium.
Compared with a basic trickle charger, this unit switches to float mode once a battery is full, which keeps it topped off during long storage without the overcharge risk of a simple charger. Lithium owners get a dedicated LiFePO4 profile rather than forcing a lead-acid setting onto a lithium pack. Spark-proof connection, reverse-polarity protection, and short-circuit protection add a margin of safety for first-time users, and the 5-year limited warranty is a meaningful term at this price point. Long-tail searches it fits include 12V powersports battery maintainer LiFePO4, motorcycle winter storage float charger, and ATV selectable lithium lead-acid charger.
Yes. The manufacturer states it supports LiFePO4 lithium batteries alongside lead-acid types. Select the lithium mode with the SELECT button before plugging the charger into AC power.
The manufacturer describes the unit as designed for indefinite connected storage, since it moves to float mode after a full charge.
The manufacturer supplies alligator clips and a ring-terminal cable. The clips suit temporary hookups, while the ring terminals suit a more permanent connection to the battery posts.
No hardwiring is needed: the charger plugs into a standard 120V outlet and connects to the battery with the included leads. The manufacturer's guidance is to set the chemistry selector before plugging in, keep the charger unplugged while attaching clips, and connect red to positive and black to negative. Attach ring terminals directly to the posts for a longer-term setup, and disconnect by unplugging the charger before removing the leads.
