The BatteryGuard technology on a Coleman 300M LED Flashlight stops battery drain, so you'll have Power When You Need It

On a normal flashlight, there is typically some residual drain as long as the batteries are connected to the circuit, even when the light is off. By turning off a BatteryGuard flashlight, the batteries are completely disengaged so the flashlight retains its brightness twice as long and the batteries last 25% longer. The comfort-grip design helps minimise the chances of dropping your light, and if you do, the strong, lightweight aluminium construction and rubber-edged bezel is water and impact resistant to falls of up to two meters.
That's twice the impact resistance of most other lights. No matter the situation, a flashlight with BatteryGuard technology is ready to use.

• BatteryGuard technology disengages batteries to preserve battery life and reduce corrosion when light is off

• BatteryGuard technology automatically engages when you turn off the flashlight
