Obscure item, but worked great
A super old machine I have uses these for some weird reason. They are the exact same model number so it’s easy to find replacements. Worked great! Make sure the model number matches, don’t trust how they look they can be different voltage but look similar

Saved my computer!
We had a very old computer that had data on it we needed. Would not boot up. Changed the battery and it starts up great!

Perfect fit for my SCUBA diving computer.
My dive computer uses these batteries as its power source. The ones I ordered from Amazon are exactly what I needed and were the perfect fit. This is my second time ordering the batteries from here.

They are batteries
I am using them in vintage computers. They do what they are supposed to do.

DEAD ON ARRIVAL!!!
These 1100Ma batteries from this maker at least suffer from poor quality control. I had to peel the plastic labeling off two of them to reduce the diameter sufficiently to fit them in my device. Those two were dead. The second two from the same brand slipped right in to my device without peeling, but were also dead. I DO NOT RECOMMEND THIS BRAND whoever sells them and DEFINATELY WILL NOT BUY THIS BRAND AGAIN FROM ANYBODY.
