Lithium-Ion Battery Usage Guidelines:
Lithium-ion batteries do not require activation before use. However, their performance and battery level calibration may stabilize after 2 to 3 complete charge-discharge cycles. To maximize battery lifespan, avoid frequent deep cycling (fully charging and fully discharging), as it is not necessary and may accelerate wear over time.
Voltage Compatibility Guidelines for Battery Replacement:
When replacing a battery, it is recommended to choose a model with a voltage close to the original to ensure stability and safety. Batteries rated at 10.8V and 11.1V are generally compatible, as are those rated at 14.4V and 14.8V. However, always verify compatibility with your device's specifications before installation.
