Cameron Sino HNV215B HNV215B12 EPP72L15D 2500mAh 7.4V standard battery

Direct replacement for HNV215B models

This lithium-polymer battery replaces the original pack in devices using part numbers HNV215B and HNV215B12. It matches the factory voltage of 7.4 volts and capacity of 2500 milliamp hours. The fully decoded chip communicates with the host device exactly like the original component. Dimensions are 74.00 by 45.60 by 23.80 millimetres.

Steady output through a full discharge cycle

The 18.5 watt-hour cell delivers consistent voltage under continuous load rather than only in short bursts. Integrated protection guards against overcharge, over-discharge, over-voltage and short-circuit events during extended use. A new pack reaches its rated performance after two or three complete charge and discharge cycles. The connector must be seated securely for reliable operation.

Low heat and silent operation in normal use

Lithium-polymer chemistry runs cool during typical indoor or outdoor workloads with no moving parts to generate noise. Power draw follows the device's own demand profile without added overhead from the battery circuitry. Shock-absorbing foam in the packaging protects the cell during transit so it arrives ready for installation. Avoid low-quality third-party chargers to preserve long-term health.
