4. Operating Instructions
These NiMH batteries are designed for repeated use. Always use a compatible NiMH battery charger to recharge them. Avoid mixing new and old batteries, or different types of batteries, as this can lead to leakage or damage.
The low self-discharge technology ensures that the batteries retain a significant portion of their charge even after extended periods of non-use. This means they are often ready to go when you need them, reducing the need for frequent recharging.
