How to use

Before installation, verify that the battery's voltage, shape and connector match the device requirements. Power off the device and, if applicable, disconnect external power before removing the existing battery. Install the battery in the correct orientation and secure any latches or screws as required by the device. Charge the battery with the device's original charger or a charger specified by the device manufacturer. Observe standard Li-ion charging practices and allow the battery to complete a full charge cycle before initial full-load use.

Usage recommendations

Store and use the battery within recommended temperature ranges defined by the device manufacturer, avoid exposure to high heat, mechanical stress, or liquids, and follow local regulations for disposal or recycling of lithium-ion batteries. If the battery shows swelling, leaks, or abnormal heat during charge or discharge, discontinue use and dispose of it via an approved recycling channel.
