Basic questions about 14500 battery

If you’re going to buy a AA light and want to use AA cells do yourself a favor and stay away from alkaline cells. They don’t perform nearly as well in such a high drain usage and are rediculously prone to leaking and ruining the light. They’re more expensive but eveready ultimate lithium’s are worth the extra and don’t leak. This form factor is a really nice choice for both edc and back up.

I’ve seen what you mean about the alkalines. For that reason, I check the batteries in all devices once a month in order to catch leaks early before they cause any real damage. For high drain flashlights and my digital camera, I only use NiMH batteries.
