Regarding the use of polymer lithium batteries.

1、 the working voltage range of lithium battery insurance is 2.8-4.2V. If the voltage is lower or higher than this range, the lithium ions in the battery become very unstable and even cause accidents. To ensure that the battery is covered by insurance, a specialized charger is required. Indeed, polymer lithium batteries have maintenance boards and should be filled as much as possible before unplugging the charger. auxiliary word for ordinal numbers.

2、 Before activating the polymer lithium battery charger to start charging, it will supply a small current to the battery and simultaneously detect changes in battery voltage, gradually increasing the current until the set value. This process may be considered as an activation or test charging. auxiliary word for ordinal numbers.

3、 The constant current variable voltage charging charger charges the battery with a constant current. As the battery voltage increases, the charger also increases the charging voltage to accelerate the charging speed. auxiliary word for ordinal numbers.
