Good batteries so far
It's difficult to review something that has a 10 year shelf life, so all I can say is we replaced the batteries in our alarm system at home and the batteries worked fine.I tested a few as per the instructions, and they were fully charged.Time will tell if they continue to hold charge, but I can't fault them at the moment.

Not long lasting.
These don't last very long. Bought them for an alarm system. Should last two to three years before changing, but these only lasted months in one unit. Have had to change twice in a short space of time.

A batch of 10 - all under voltage!
I bought a 4 pack of these same batteries in March 2023 and the same 4 pack in August 2025. They power a number of WiFi connected sensors on my security system. 3.6v is an absolute requirement otherwise the sensor can't connect to the controller.On previous occasions there's never been a problem, I didn't use all of the batteries immediately, it was usually a few months after they were delivered before the last one was used.So, on this occasion I thought it a good idea to order a 10 pack. The day after it arrived I took one of the newly arrived batteries to replace the battery in one of the sensors, which failed to connect to the controller. I checked the voltage on the new battery, it was 3.35v. I checked the other 9 and found them all to be below specification - one was as low as 3.14v. I listed the voltage on the inside of the 'lid' of the box (see photo) then returned it for refund.

Goed geholpen door fabrikant/leverancier
Dit is mijn tweede review. Ik ben benaderd door de leverancier. Kreeg gratis nieuwe. Die zijn een stuk beter (zie laatste afbeelding). Wanneer ik een SAFT erin doe, dan is het 100%. Laten we het erop houden dat ik een slechte batch had. Je kan ze met een gerust hart kopen. De leverancier help erg goed bij problemen. En de prijs is natuurlijk laag. (Hierna mij oude review) Waar andere merken 100% aangeven doet deze maar 30% na korte piek van 70. En twee dagen later nog maar 20%. Andere uit het doosje geprobeerd, 45%Niet best dus voor die prijs.

Battery for old macintoshes
Works as expected in old macintosh computers (IIsi, IIcx, SE etc). Note, needs to be removed before long-time storage (years).

9 of 10 bad. Don’t buy.
I used one immediately in a water sensor, worked fine. 2nd one a couple of weeks later, same. 2 weeks later needed to replace another one, wouldn’t power up my sensor. Very low voltage under load. Noticed the second was working but reporting only 58%. Tested the other 8 batteries, all very low. Company won’t return emails. Recommend Saft brand.
