ER14250 3.6V 1/2AA Lithium Standard Battery Button Top

I am satisfied with the product and the service. It is such a small battery and it is doing what it should.

This is a hard to find battery. I was glad to be able to purchase it thru Amazon. It works well in my fingertip blood oxygen monitor.

At first I wasn’t sure what was shipped to me since the seller put these batteries in a box for a different product. My door detector only uses this type of battery and no one will ship batteries to Hawaii. It’s working well so far.

Expired date code on new battery: Batt received in good shape, and works in my application. BUT, the date code on the NEW batt is the SAME as the old batt being replaced. It works okay. (The date code is "JUN 22" on both the old and the new. Today is "NOV 24"...)

My husband needed it for his pulse oximeter, glad he’s able to use it again now.

works as it should

Found this battery on Amazon of course..i use it in my BPM and blood oxy finger clip many times a day. I've had this battery a long time and has never failed...an excellent strength long lasting battery.

It is a perfect fit where other brands are smaller , shorter ,different diameter so if size matters then this is exact fit.
