Most DSLRs, Mirrorless Cameras and Video Cameras are powered by rechargeable lithium-ion batteries. When the charge runs low you’ll need to remove the battery pack and plug it into a camera-specific battery charger or a universal battery charger.
Battery chargers run off mains electricity and will recharge your camera or camcorder battery in a couple of hours. Actual recharge time depends on the capacity of the battery being charged.
Need a battery charger that switches to trickle charge once your battery is ready? With today’s intelligent universal battery chargers you’ll be able to do this, no problem.
