When a battery is subjected to extreme vibration and shock, cracks occur at the interface of mechanical joints inside the battery and its cells resulting in battery failure. While some batteries are designed to withstand these forces better than others, all batteries can be damaged by shock and vibration over time resulting in low voltage and insufficient power. The Megaware BatteryGuard sits under your battery and absorbs up to 80% of the G-Shock caused by excessive shock and vibration. Protect your batteries from premature battery failure with Megaware BatteryGuard.
