Charger finder

Find by battery voltage, chemistry and charger mode

Start from the battery maker's label and instructions. This finder applies only requirements that are supported in an authored model record; an empty result is a useful boundary, not a reason to guess. Its 12 V device-supply choice is a separate power-supply mode, not battery charging.

It is not a battery-health test, a charging-time guarantee or a substitute for an exact-model manual. Leave optional measurements open unless they are essential.

Your everyday needs

Start with where and how you will use it. Choose the features you need, and leave a choice open when it is not essential.

This is the battery's nominal voltage, not the charger’s AC outlet voltage. Keep this open if you are comparing possibilities.

Check the battery label or its maker’s manual. Lithium and lead-acid batteries need their corresponding mode; do not guess.

Choose a subtype only when confirmed on your battery label or instructions. AGM charging may use a separate mode, and the reviewed GENIUS10 is the only model here whose exact manual documents a 6 V AGM mode.

Recharging a depleted battery and maintaining one that is already charged are different jobs. GENIUS10 also has a separate 13.6 V Supply mode for compatible 12 V DC devices; that is not a battery-charging mode. Leave other answers open when considering that supply mode.
