Kastar MX990 twin-pack camera batteries

The Kastar MX990 is a two-pack of lithium-ion camera batteries rated at 3.7V and 1900mAh each, delivering 7.03Wh per cell. They are built as direct replacements for the listed DM-Tech, Govideo and JNC part numbers and fit the DM-AV10, PVP4040, SSF-M2 and SSF-M20 models.

Replaces original DM-FV10BP and CS-SFM2SL cells

These batteries replace the original DM-FV10BP and CS-SFM2SL packs used in compatible camcorders. The jump is worth it when the original cells no longer hold a charge or when longer run time per session is needed for extended recording.

Verify your device uses the listed part numbers

Check that your camera or camcorder accepts the DM-FV10BP, CS-SFM2SL or equivalent part numbers shown in the compatibility list. Confirm the battery compartment fits the 3×2×2 inch form factor and that the 3.7V voltage matches the original specification.

Questions about this item

What battery compartment size fits the 3 by 2 by 2 inch Kastar MX990?

The MX990 measures 3 by 2 by 2 inches, so it fits any camera or device whose battery bay accepts those exact dimensions.

How do I install the MX990 batteries and what step is often missed?

Slide each 3.7 V 1900 mAh pack into the compartment following the polarity markers, then fully charge both units before first use — skipping that initial charge is the common mistake.

When will the MX990 packs need replacing and how can I extend their life?

Expect several hundred charge cycles; avoid deep discharges, store at roughly half charge, and keep them cool to maximise the lifespan of the lithium-ion cells.
