Buyers needing a direct replacement

This battery suits owners of devices that accept the M31120B, LP553450, 02404-0022-00, 02404-0019-00 or 1UF553450-1-T0423 part numbers. It is not for users who require a different voltage, a higher capacity or a multi-pack configuration. Builders needing a cell with alternative dimensions or connector placement should look elsewhere.

1200mAh capacity at 3.7V

The 1200mAh rating at 3.7V determines whether this cell fits the runtime and power envelope of the target device. Verify the original battery lists exactly 1200mAh and 3.7V before ordering. A mismatch in either figure means the pack will not operate correctly.

Questions about this item

Does the 1200 mAh 3.7 V cell run hot or draw extra power when the Flip runs all day?

The 4.44 Wh lithium pack is built to the original specification and includes over-charge, over-discharge, over-voltage and short-circuit protection, so heat and power draw stay within the maker's limits.

Must I already own a Flip device that takes the M31120B or LP553450 part number for this battery to work?

Yes — it only fits models that list M31120B, LP553450, 02404-0022-00, 02404-0019-00 or 1UF553450-1-T0423 as the approved battery.

Will this 50.2 × 36.7 × 5.5 mm pack sit properly in an older Flip unit that still uses the original battery tray?

The dimensions and 49.0 g weight match the factory cell exactly, so it seats in the existing tray without modification.
