As well as talking to Bailey, and lusting after Buccaneer & Bessacar ‘vans at last week's Show, I was also able to spend some time with a very helpful guy on one of the Battery/Accessory stands. Turned out he was something of a man & boy battery expert, and we had quite a long, and very useful chat. During the course of the chat, he brought out a (non identifiable) leisure battery technical comparison chart. Not unsurprisingly, as with all things, and with batteries in particular, you only get what you pay for, but unlike Ronseal, battery ratings do not necessarily mean what they say on the tin. Amongst the specification most of us look for when buying a leisure battery is the “amp/hr rating”, as a guide to how much charge they should have available. With a little judicious arm twisting, I was able to persuade our battery expert to identify one of my batteries on his chart. When it was sold to us for something over a hundred quid for a 115 amp/hr rating, “fully backed” by a two year warranty, it didn’t seem to be an unreasonable price, not top spec, but not too cheap and cheerful either. Trouble is, on the Show stand technical comparison chart, the 115 amp/hr rating for this particular battery, in reality tested out to be rather less than half that, at 52 amp/hr. No ******* wonder we have been having battery problems. Even if my other 115 amp/hr battery, which he couldn’t identify, is up to snuff, there is no way while they are connected in parallel in the 'van, that the solar charge system is going to cope with such a disparity. Problem is, if a battery states 115 amp/hr rating “on the tin”, but the tin is actually less than half full, then as I wrote in my previous post, how the average ‘vanner is going to find this out beats me.
