You’re correct—charging a Li-ion battery with a NiMH charger is not advisable. Each type of battery has specific charging requirements:
- NiMH Chargers: These are designed for nickel-metal hydride batteries and operate with different voltage and charging algorithms compared to Li-ion batteries.
- Li-ion Batteries: Lithium-ion batteries require chargers that manage their unique voltage levels and charge profiles. Using the incorrect charger can lead to unsafe conditions, such as overheating, reduced battery life, or even fire hazards.
- LiFePO4 Batteries: These have their own distinct charging profile and voltage range compared to other lithium-ion types. A charger specifically designed for LiFePO4 ensures that the battery is charged correctly and safely.
In summary, while it might be technically possible to use an incompatible charger, it is strongly recommended to use a charger designed for your specific battery type to ensure safety, performance, and longevity.
