‘Just the facts’
Remember:
- Do not mix batteries of different types or brands. They will discharge unevenly and can ultimately rupture and fail.
- Using the wrong battery type affects the accuracy of your battery indicators or alarms. Developers designed night-vision devices, thermal sights and target locators to use L91 lithium AA batteries. Alkaline batteries will not accurately indicate, or alarm, their state of charge, but lithium batteries will.
