Replacement Battery for 70mai HMC1430

This nickel-zinc replacement battery is built for 70mai devices that use the HMC1430 part number. It delivers a 650mAh capacity and 2.41Wh energy rating at 3.7V, matching the original specifications. The pack measures 45.50 x 14.50 x 14.50mm and weighs 19.0g. A fully decoded chip ensures it works like the factory cell.

Upgrading from a Depleted Original Cell

The jump is worth it when the original battery no longer holds a charge through a full recording cycle or shows swelling. A fresh cell restores the dashcam’s ability to capture parking-mode footage and maintain settings without a constant power lead. It is not for users who need a higher capacity than 650mAh or a different form factor for a modified housing.

Nickel-Zinc Chemistry Limits

Nickel-zinc chemistry operates at 3.7V and requires a compatible charging circuit; it cannot be charged with a generic lithium-ion charger. Do not store the cell above 60°C (140°F) and allow two to three full charge cycles for optimal performance. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection, but it lacks the energy density of lithium chemistries for extended runtime.
