Customers like the battery life of the tools. They say the batteries are long-lasting, do not leak toxic oil, and have a long shelf life. They also say the lithium cells not only make their flashlights last longer, they increase the brightness, and do not spill. Customers also mention that the batteries outlast regular alkaline cells by multiple times. They hold up great, store for much longer, and are very good as battery backups for hard-wired smoke and CO detectors.

Great batteries; Great customer service
Item originally came out in a plastic case and they let me return the batteries for a 4 pack in the normal store packaging. They also sent a return-shipping label free of charge.You are able to get a better price if you accept the batteries in the plastic case, I just wish the item description picture would look like what they sent me, so I have downloaded a picture of both for you to view above.Prompt, great customer service.
Thank you for your feedback
