It works...
Charged a newer type calcium battery that my previous charger refused to recognise so happy with purchase! Build quality not greatest, but reasonably priced so not an issue.

Good value @ easy to use.
Charger is well made, easy to use @ efficient. Good value. Instructions could be better for people who are not used to using chargers.

technical support - Edward at leeds - wonderful
Nothing to dislike, great product, does what it says and above all I could ring the technical team and ask what might slighty ameuter questions and be given good solid advice with any condesending comments.Ive bought a lithium battery for my caravan and did a bit of research to get the correct charger but the battery company put some wierd get out clause on the top of battery saying it needs a copper ring to charge it....... if using crocodile clips, and they did provide it, however, Ring did so i spoke ot Edward and sent him photos and I realise this is going to be fine top marks to Ring and I wish Id bought the battery from them too :-) Next time I will. thanks

Died within three months and took battery with it
Worked fine for two months, noticed it had switched off so checked the battery and this was totally discharged (new battery). I then put it on to another battery, it worked for 10 seconds and died again.Do not trust this product without checking it regularly. Read other reviews

Safe to use with a range of battery types
Easy to use battery charger and optimiser, I tried it on my boat batteries and it brought them up to full charge and continued to monitor the battery without any damage. Also the unit is weatherproof which is ideal in a maritime setting or could be used in a garage just as easily

Good not great
Worked faultlessly for less than a month and one day just decided not to work at all, I was using it to keep my old car battery from draining (barely gets used) checked the fuse and it wasn’t that. Fortunately the customer support was fantastic and I got a replacement in the form of the 6a model which has been perfect highly recommend the 6a

Useful little car battery charger
Really pleased with this tidy little unit, which is self-managed, meaning you can leave it connected to the car battery without worrying about overcharging. I own several cars, and some go unused for weeks at time. Multiple connector options in the box allow you to hardwire a socket to the battery for quick connection inside the car, and I can just leave the charger to do it's thing without even opening the bonnet.
