Can I use a NiMH battery charger to charge Li-Ion batteries?

No, you should not use a NiMH charger to charge Li-ion batteries. NiMH chargers are designed to charge nickel-metal hydride batteries, which have different charging algorithm compared to lithium-ion batteries.

Li-ion batteries require a specific charging voltage and current, and using a charger designed for NiMH batteries could result in overcharging or undercharging the Li-ion battery. Overcharging a Li-ion battery can lead to thermal runaway, causing the battery to catch fire or explode, while undercharging can reduce the battery's performance and lifespan.

It's essential to use a charger specifically designed for Li-ion batteries, and if you're not sure about the compatibility of your charger with your battery, it's best to consult the manufacturer's instructions or a professional before attempting to charge the battery.
