How to use

Install the HP 922752-421 18650 cell only into battery holders, packs, or devices designed for 18650 lithium-ion cells. When assembling or repairing a multi-cell battery pack, ensure correct cell orientation and secure electrical connections; cells should be matched for capacity and state of charge to maintain pack balance. Use an appropriate charger and a battery management system (BMS) that supports lithium-ion chemistry and the pack configuration to control charging, discharging, and cell balancing. Follow device or pack manufacturer's guidance for assembly and safety.

Recommendations

Handle lithium-ion cells with care: avoid short circuits, mechanical damage, exposure to high temperatures, or improper charging. Store cells in a cool, dry place at partial state of charge if not used long-term. Use protective circuitry and follow safety instructions of the device or battery pack manufacturer when assembling or replacing cells.
