Installation Notes and Common Issues

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.
