Frequently asked questions
What kind of charger should I use?
Use a charger rated for a 4V lead-acid battery. A charger designed for 12V or for lithium cells will overcharge or undercharge this battery.
Can I use it to power a 6V or 12V device?
Not directly. The nominal output is 4V, so match the device voltage or use a suitable DC-DC converter to step the voltage up.
