6-Volt Battery Chargers & Maintainers
High-Tech Battery Solutions carries name-brand 6-volt battery chargers, trickle chargers, and maintainers from NOCO Genius, Deltran Battery Tender, and CTEK - for a child's Power Wheels ride on, a classic car, a vintage motorcycle, a lawn tractor, or a battery in seasonal storage. Most of our 6-volt chargers also handle 12-volt (and some 24-volt) batteries, so one unit can cover the whole garage.

Can I use a 12-volt charger on a 6-volt battery?
No. A 12-volt charger pushes roughly 14 volts into the battery, which badly overcharges a 6-volt battery - it will gas, overheat, and can be permanently damaged. Use a charger set to 6 volts, or a multi-voltage smart charger (like the NOCO Genius line) that you switch to 6V mode. On a NOCO Genius you hold the mode button for a few seconds to select 6V.
What amp charger do I need for a 6-volt battery?
Aim for a charge rate of about 10 to 20 percent of the battery's amp-hour capacity. A small 6V toy, motorcycle, or lawn-equipment battery charges nicely at 1 to 2 amps; a larger deep-cycle or car battery can take 5 to 10 amps for a faster charge. When in doubt, a lower amp rate is always safe, it just takes longer.
How long does it take to charge a 6-volt battery?
A rough estimate is the battery's amp-hours divided by the charger's amps, plus about 20 percent for the final absorption stage, so a 10Ah battery on a 2-amp charger takes roughly six hours. A smart charger stops automatically when the battery is full, so you can leave it connected.
Can one charger handle both 6-volt and 12-volt batteries?
Yes. Most of the chargers on this page are 6V/12V (and some also do 24V), so a single unit can charge a motorcycle, a car, and a ride-on toy. You set the charger to match the battery - on a NOCO Genius you hold the mode button to choose 6V or 12V.
