Am testing out a load of solar gear in my back garden, have a old 17AH lead acid battery from a UPS, trying to find out if it will hold a charge. You have to keep batteries topped up with power otherwise they deteriorate over time.

UPDATE: it did not hold a charge I had to go out and buy a new battery from maplins, which works fine.

UPDATE2: I damaged the new battery so have to replace that, by charging it with out a charge controller, was using a volt meter to keep an eye on its level manually, but it only took one time forgetting and leaving it out in the sun to damage the battery – get a charge controller as human beings are prone to fail (:
