Installation Notes and Common Issues

The pack slides into the internal battery bay after removing the bottom case screws and disconnecting the old connector. No soldering or firmware update is required. The most frequent problem is ordering the wrong voltage variant, so verify the 11.55V label on your original battery before purchasing.

Sustained Load Behaviour

OEM-grade lithium polymer cells deliver steady output during long work sessions without the voltage sag seen in lower-grade packs. Built-in protection circuits guard against over-charge, over-discharge, over-heat and short-circuit events, keeping performance consistent through repeated daily cycles.
