The item is as described. Working very well and charging my second leisure battery. I would recommend this product if your vehicle has a "Smart" alternator and you do not want the hassle of taking out the battery to recharge regularly. The split relay charging method does not work with smart alternators as this is what I replaced with this CTEK DC to DC charger.
Ordered the CTEK D250SA from Tayna and initially they were out of stock but managed to fulfil the order by the following week. Spoke to a very pleasant guy who explained what was happening and said it would be delivered and it was delivered on the day he promised. Great product, well packaged and at a good price. Well done Tayna. Will be back to buy 12v deep cycle batteries soon.
