Introduction
The Gamesir G4 Pro is powered by an 800 mAh rechargeable battery. The four small red lights on the left side of the controller indicate battery life before it needs to be recharged. If the controller has been plugged in to charge without the lights indicating increased battery status, then the battery may be faulty and need replacement.
The 800 mAh battery is an internal part that requires opening the controller to replace. We advise that you wear an anti-static wrist strap when handling the battery to prevent electrical shocks. If the battery is swollen or hot, take precaution and dispose of it in a fireproof container as the battery is highly flammable.
