Cameron Sino WWH-ACC200 2500mAh 7.2V camera battery

Replacement battery for Maxon SP series

The Cameron Sino WWH-ACC200 is a 2500mAh 7.2V lithium-ion pack built to replace the original Maxon WWH-ACC200 cell. It fits the SP300, SP310, SP320, SP330 and SP340 two-way radios and carries ISO9001, RoHS and CE certification. A fully decoded chip ensures communication with the radio matches the factory unit. The pack measures 131.50 x 56.00 x 18.50mm and weighs 227.6g.

Upgrade from depleted or ageing original cells

When the stock battery no longer holds a full shift charge or shows swelling, this unit restores the original 18.0Wh runtime without modification. The jump is worth it if your radio cuts out early, the charge indicator becomes unreliable or the pack has passed two to three years of daily cycles. Installation follows the same connector orientation as the factory pack and numerous online videos demonstrate the process. New cells reach peak capacity after two or three complete charge and discharge cycles.

Capacity and headroom for daily radio use

At 2500mAh the pack delivers the rated 18.0Wh for typical push-to-talk duty cycles across a standard work shift. It comfortably handles continuous receive with intermittent transmit on standard power settings. Runtime shortens when operating at maximum transmit power, in very cold conditions or when using low-quality third-party chargers that stress the protection circuit. The built-in safeguards guard against overcharge, over-discharge, over-voltage and short circuit but cannot compensate for cells worn beyond their chemical lifespan.
