I often get asked how long an LR44 or AG13 battery will last in something like a LED tea light or a small calculator. This matters because nobody wants to replace batteries every week for a device that barely uses power. In my experience, a quality LR44 can keep a low-draw device running for well … Read more

I often get asked if alkaline LR44 AG13 batteries die faster sitting in a drawer than lithium cells. This matters because nobody wants to grab a spare battery only to find it’s dead before you ever used it. In my experience, alkaline LR44 batteries lose about 2-3% of their charge per year just sitting on … Read more

I used to toss old LR44 and AG13 batteries in the trash without a second thought. Now I know that’s bad for the environment and even a little dangerous. The real kicker is that most recycling centers won’t take just a couple of tiny cells. They have strict rules, so I have to save up … Read more

You found a stash of LR44 AG13 batteries after a decade in a toolbox, only to discover white crusty corrosion. This is a common frustration for anyone who stores spare batteries for emergencies or old electronics. Even brand-new batteries can leak over time due to chemical breakdown inside the sealed casing. That harmless-looking powder is … Read more

I used to toss old batteries in the regular trash without a second thought. But I learned that lithium LR44 AG13 cells are different and need a special disposal collection point for safety. These small batteries contain reactive lithium that can cause fires when crushed in landfills. That is why many stores and recycling centers … Read more

I have noticed my LR44 and AG13 batteries draining much faster when the temperature drops. This is a common problem for anyone using small electronics outdoors in winter. Chemical reactions inside these batteries slow down significantly in cold weather. In my experience, a battery that lasts months in summer might only last weeks when it … Read more
