Fantastic
Absolutely fantastic, it arrived 5 days earlier than expected and it worked straight away, it even came with a cable connector for the Siren, which I did not expect but it was nice to put a fresh connector in. Saved me so much money, last year the alarm guy charged me £200 for fitting these batteries alone and they did not even last a year, so even if this one last 6 months I already saved loads.

Alarm bell batteries, work perfectly and easy to install
The guys at SD fire alarms are complete professionals and after an initial mix up beyond their control reposted another package off their own backs and out of their own pockets. Couldnt be happier with my purchase. These guys went above and beyond.

Cheaper than getting alarm firm
Batteries went it fine, no problems at all. Were going to get alarm company out to change them but they wanted £130 bit of a difference in price. 😲🙌👍

Poor quality

Buy the pair.
Perfect replacement for the original batteries that have been in the siren box for five years. Have to wait and see how these perform. Bit expensive I thought, but Amazon was the least cost. Buying the pair as opposed to singles helps to keep the costs down.
