Battery size it is rated to recharge
A maintainer first
The Junior is built for batteries that sit: motorcycles over winter, classic cars, mowers, powersports. Battery Tender's page describes it as switching between lead-acid and lithium modes, which is the reason to choose this version over the standard lead-acid-only Junior (SKU 021-0123).
Battery Tender does not publish an Ah range on the product page we checked, so we do not state one.
