Duracell 4.5 Volt -

It works. However, if like me, you’re using it for a disc alarm lock, you may find that the “nib” on the battery is shorter than some other batteries, and you may need to use a pointy knife and bring the contact points closer to the battery in your device

Works as intended for our alarm system (beams in garden).

well price perfectly functional and delivered earlier than anticipated.

It is Value for money and it reached me in a good condition

Very good product, I am completely satisfied so far and will buy them again.
