The 8 Best LR44 Batteries
This wiki has been updated 14 times since it was first published in November of 2017. If your wristwatch, pocket calculator, or hearing aid suddenly runs out of juice, then you'll be glad to have some LR44 batteries, also referred to as AG13s, lying around the house. These 1.5-volt alkaline button cells are among the most common types of power sources for small electronic devices, and they can last for years in some applications. They often come in bulk and are pretty cheap, too. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki. Skip to the best lr44 battery on Amazon.

You’ve got a range of options here and your pick will really depend on whether you prioritize cost or quality. Generally, a 1.50V LR44 battery has a capacity of around 150mAh, so discharge time depends on the power needs of your application, of course. Energizer is always a reliable and trusted option, if you don’t mind paying marginally more for the brand name. If you don’t want to do that then the LiCB 20-Pack and Amvolt Round Cells are both good, durable picks. I’m quite a fan of Amvolt’s batteries since I have a Casio watch with an Amvolt LR44 that I’ve taken through some pretty extreme weather conditions. It’s been well over a year now and it’s still ticking on with the same battery.
Price isn’t always a measure of quality, but it is relatively good estimate, and you’ll see that here in this list too, with options from household names like the Sony Alkaline Batteries and Energizer Button 20-Pack being more expensive, but offering slightly better quality too and lower self-discharge rates. However, there are quite a few notable exceptions here like the Maxell 2 Pack, which comes from a known battery brand/manufacturer, but whose cells seem to offer only average results in terms of capacity and life.
On the flip side, some of the lesser known and more ‘generic’ brands have been surprisingly impressive. The cells in the LiCB 20-Pack seem to last forever, despite being so cheap. They would be my ‘best-value-for-money’ pick. Do keep in mind that batteries also tend to get cheaper per-unit-cost when bought at large quantities, but I didn’t want to saturate the list with 100-packs since you probably don’t need them and they aren’t always sold like that anyways - but if you were looking for a bulk-buy, then I’ve left in the Loopacell 100 Pack.
Note that the voltage in alkaline batteries (like the LR44) decreases with battery life (or battery usage), which is a measure of the capacity left. At 50% capacity, the voltage in an LR44 battery typically drops to below 1.3V. LR44 batteries are quite good however for ultra-low-power, long-term operations, and that’s why they’re frequently used in motherboards, along with CR2032 batteries. LR44 batteries also typically have a self-discharge rate of around 5-10%, depending on the quality of the battery.
LR44 can be replaced with multiple alkaline and silver-oxide batteries. The SR44 is a good silver-oxide replacement and it has a stable operating voltage throughout its life and then drops towards the end (after around 90-95% usage).
