This is the one that I use for charging the car battery and leisure battery as well. It works for both gel and standard batteries and as some sort of computer conditions the batteries and charges. I bought it from Halfords I can't remember how much it was around the £60 I believe. I have used the small trickle charges but this one is the best I have ever used. it works a treat and can really along the life of your batteries. Excellent Product February 22, 2011 By Strat from Sheffield, UK Due to the recent cold weather and numerous short journeys my battery finally wouldn't turn the engine over or even unlock the doors. I picked this product largely on reviews here and wasn't disappointed. The battery was down to 9.4 volts but the Halfords Smart charger had it fully charged in 2 hours. Great product. Bit on the expensive side but it does it's job well. Very Good Product January 30, 2011 By Pickles1942 from Northampton After reading the instructions it was very easy to link up with my Battery and read the dials etc, checked every hour and after 3 hours the battery was fully charged bearing in mind that it was a Heavy Duty Battery on a Jaguar 2.7 S-Type Diesel Auto. Would recommend to anyone, one of my better buys. Battery Charger January 9, 2011 By KMal from Welwyn, England Robust looking unit, gives more information than most regarding the condition of your battery. Recommended. SUPERCHARGED SUPER CHARGER January 4, 2011 By EIGER from South Bucks This worked brilliantly and was an excellent buy, It was simple to use, safe and instructions were clear, though a bigger print size would have helped The leads are a little on the short side but it really is not difficult to work round this. Once connected which was a quick, straightforward operation, it took little more than an hour to do its job. In short I'm delighted with it. WOT IT SAYS IS WOT YOU GET!
