These batteries are direct replacements for those included in our key fob and hand-held remote transmitters. If the usable range of your transmitter is dropping, and/or the LED is dimming or not illuminating at all then you should replace your battery for a new one.
Our hand-held transmitters take a larger 'A23' 12V battery, older plastic fob remotes take an 'A27' 12V battery while chrome-edged fob remotes take a pair of 'CR2016' batteries each.
The batteries are supplied individually, select the size you require from the options below.
Batteries are brand new.
