10 x PoundMax SR44 1.55 V Silver Oxide Button Cell Battery

Work as they should, they seem to last long and much cheaper than other brands

These are Chinese unbranded batteries, seem to be of a good quality, expire date in 5 years. These SR44 (silver oxide alkaline) can be used as an upgrade to LR44 (alkaline), as the silver ones usually have about 50% more capacity, a flatter discharge curve, allowing to use more of its capacity before the voltage drops, and longer shelf life due to lower self-discharge. I am not sure if this is relevant, but the silver oxide cells tolerate winter temperatures much better. These are cheap, so a good deal.

I've found most of these to last an exceptional amount of time. There was one maybe two that didn't last quite as long. I imagine you'll get that with mass production. So all in all great battery life and I'm very pleased with them.

Long use by date

Not a lot you can say about these, a standard SR44 button cell that does whats asked of it. The SR (silver oxide) usually last longer than the LR44, which is only an alkaline cell. Only time will tell when I start using them.

Edit to my previous review: Some are working so I'll settle for 3 stars. Packaging, listing and product do not match. Speedy delivery. Will update later on should these prove good quality after all. Will be gutted if it's my camera not the batteries.Original Review:Bought for Olympus OM2N, they don't work. They could be flat, or it could be that the Amazon listing says SR44, the packaging says SR44W, and the batteries say SR44SW. Either way, these are crap and don't work like SR44's should. Probably isn't even Silver. Want money back. Want my wife back.

Good priced silver oxide batteries.

Only just used a few so far but they seem OK
