What more can I say. It's a battery that I needed replacing for the car key. It works... How long for I do not know. If it lasts less than a year I'll be annoyed and if more than a few years great. Will keep you posted.

As described and arrived on due date

Good product and as described.

MANY THANKS

Item was as described and replaced one which had been in place for some 11+years. Two problems. This model required a larger hole in the top of the tank than the one it replaced. This caused some difficulties in enlarging the hole but after an hour I managed to file away enough to get it to fit. Secondly and more importantly, despite following the "pairing" instructions precisely I was still left with a flashing red light on the receiver. Despite repeating the pairing instruction several times I could not get rid of the red light. So on phoning the manufacturers I was told it was due to the oil level in the tank being so high it could not set itself until the level had reduced. I had just had a new load of oil delivered. So after about a month when my oil use had lowered the level I now have a fully functioning receiver. My point is that you should mention this in the instructions to save all the trouble I have had and probably other users as I surely cannot be alone. One final point. Could you not make it easier to change the batteries? I realise you need a secure and airtight joint but after the unit has been in place for several years it is very difficult to access the 2 screws to detach to two sections and access the batteries due to dirt and corrosion surrounding the unit. I trust this is helpful feedback. Brian Blake

With so many different makes of battery, I found energiser one of the longer lasting makes I've used these on blood testing equipment and my key fobs for our car . Genuinely last a year but like all batteries all depends on temperature and usage Never had a set leak either !
