What can i say about batteries, well, there are shops in our area that sell things that use this type, but non of them sell the battery, so when a new one is needed the problem is where to find one. Saw these and decided to give them a try, Now we have a door bell that works again, and my multi-meter is back in action. Good price and quick delivery, now I know where to go when I need any more.
I bought these batteries to use for my remote control for plugs for the sockets. I use these to turn the TV off at the wall without having to get up off the sofa - and also to turn my uplighter on from distance.
It told me the specification for the battery on the remote control itself. But when i need to replace something I usually find the easiest thing to take it out and order exactly what it says on the battery - there seem to be so many different kinds these days.
The price is very reasonable and I have a spare battery if it needs replacing.
