When to Replace Your K518 Pro Battery

Battery cells lose capacity over time and with repeated charge cycles. Common signs that your K518 Pro needs a new battery include: the device shutting down unexpectedly during a programming job, very short runtime away from the charger, failure to power on unless plugged in, or visible swelling of the original cell. Replacing the battery is far cheaper than replacing the tool and restores the device to full portable operation.
