Vivitar DVR 781HD Battery Replacement

Move the plastic opening tool around the seam and apply force at each step to separate the front plate from the back plate and motherboard.

The battery is held to the front half of the case with double-sided tape. Peel it up with a finger, being careful not to damage the battery.

Using a P1 screwdriver, remove the 4mm screws holding the motherboard into the case.

Gently lift the motherboard, handling it by the edges.

The battery connections are reinforced by black potting compound. Gently pry it away with a plastic spudger.

Melt the soldered battery connections with a soldering iron and gently pull the battery wires away.
