Energizer3-Volt Coin Lithium Batteries CR2450 6 PK

Fast delivery

These name brand batteries last much longer than the cheap Chinese knockoffs I'd been using. My wife's key fob kept going dead after a month or two. Upon replacing with these she gets at least a year. Worth the extra cost.

It works good for my Lincoln 3350 helmet.

The last time I bought these, they came in individual packs that were sealed via a plastic back and cover. This latest set is also individually packaged, but have cardboard backs, which are not as moisture-resistant. Thus, only 4 stars.

Very fast shipping great product

Well packaged. Assuming legit, except outside package did not list battery use by date. Has 6 individual retail packaged batteries inside box. A pain to get open, and I've never bought an individual pack before so I have no comparison, but doubt a knock off would go to such effort with packaging. The original battery for this application lasted about 10 months. I'll update based on that benchmark if it happens to be significantly less. Good price if it is comparable in performance. Good use by date of 3/30 if I remember correctly.

I use these for alarm devices. They typically last 12-18 months. Easy to repair and at this price, I keep a half dozen on hand at all times.

Good price, a bunch of things I have now take this size and they’re good for the next 10 years
