   I've got the Lidl one which I bought well over a year ago and is in constant use. Does what it says on the box. Certainly it has rejuvenated my two leisure batteries, on of which was getting "tired".

 Spec says four variable charging rates max 3.8 amp charge, for 6v or 12v batteries, 1.2-120Ah capacity, 3 year warranty, made in Germany according to the paperwork. As others have said it doesn't re-set after a power cut, but that seems a minor inconvenience to me. Just picked up one for a friend last week still £12-99.

Dorset Paul:

I have just bought a trickle charger recently and started using it today. This is the one I have. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330504570406&ssPageName=STRK:MEWNX:IT#ht_2745wt_905

My question is, how long should i charge the battery for? Some say a day once a month, others say keep it charging for longer.

What is your advice please.

                        ______________________________________________

This is exactly the same charger as I have if you read my earlier post. I have today spoken to a technical electrical engineer with numerous qualifications in the trade. He confirms that this charger is absolutely fine and the ones to avoid are car battery chargers as the input feed is too high causing the Lead plates to get hot quicker which will shorten the natural life of the leisure battery. His advice is to charge the battery for approx. 16 hours without interuption and not to recharge for at least 4 months. If the battery is in good condition it should hold a full charge adequately for this period. If you charge it every month like have done for the past six years then you will shorten the life of the battery once again . I'm on my third battery now and this is the reason why I am only obtaining about 2 years life out of each one. A good lesson learned from an expert so I'm expecting my current battery to give up the ghost sometime this year. So my conclusion now is to keep my charger and invest in a secondary leisure battery as it's sod's law that it will pack up for good when we are out in the caravan.

Although our caravan is in storage, we try to go away over the winter in order to keep our battery "charged" by plugging in to the site mains.  Is this sufficint to fully charge the battery or should we remove it still, take it home and charge it there? 

Thanks

Alison

i have a 7000 ctek for general charging and i have installed a 25000 ctek in my abbey i use it in supply mode when we are away and then when we get home and everything that is 12 volt is off i then let it charge properly ie 14.4-14.6,i have two 85amp gels wired in parallel as we rally all the time,these work 100%.i know of 5 people who bought aldi-lidl chargers and they have all failed.i leave mine on all the time when the van is at home and we have no problems at all

note. i have turned the onboard charger off and have not used it in years
