Kastar MX990 1900mAh 3.7V 7.03Wh camera battery

Kastar MX990 lithium-ion camera battery

The Kastar MX990 is a 3.7 V, 1900 mAh lithium-ion pack rated at 7.03 Wh. It replaces original batteries in DM-Tech, Govideo and JNC camcorders such as the DM-AV10, PVP4040 and SSF-M2 models. The single-cell unit ships new and includes built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating. Buyers who need a multi-cell pack or a different voltage will not be served by this item.

Sustained power delivery for long recording sessions

The cell maintains its rated capacity across extended shoots rather than fading after a short burst. Protection circuits keep voltage stable during continuous draw, so the camcorder receives consistent power until the pack is depleted. This behaviour supports event videography and documentary work where the camera runs for long periods without battery swaps. Users who require hot-swap capability or parallel charging will need a different solution.

Low heat and quiet operation in normal use

Lithium-ion chemistry generates minimal heat during typical recording loads, and the pack has no moving parts to produce noise. The integrated safety circuit meets UL 1642 and CE limits, preventing excess temperature rise under normal current draw. Power consumption matches the 7.03 Wh rating, so the battery delivers its full capacity without unexpected drain. Buyers expecting active cooling or fan-assisted thermal management will not find it here.
