Proper charging voltage is around 15V at that temp, and maintenance charging is about 13.75V.<br /><br />This is based on info at http://www.powerstream.com/SLA.htm. These people really seem to know what they are talking about (they build lots of kinds of chargers). That page is very informative!<br /><br />They point out that the voltage of a transformer rises as current tapers to zero, which is why your transformer reads so high - I'm guessing you're measuring these at zero current.<br /><br />They also point out that the shut-off circuitry needed is very inexpensive. E.g. something like this: http://www.national.com/mpf/LM/LM317.html might be suitable, configured properly (but I'm not an electrical engineer).<br /><br />BTW - I'm not affiliated w/Powerstream, or even an expert on battery charging - have been trying to learn more about this myself!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1132186614818416309.post-76283067589378791252008-04-06T14:45:00.000-07:002008-04-06T14:45:00.000-07:00I found an old 12v transformer in my box of old on...I found an old 12v transformer in my box of old ones and ones that I lost track of what they were supposed to charge. I went to Radio shack but they did not have female plugs at all. By the way, the plug was size 'M', if you want to try and get one. Anyway, I got two spring loaded clips at the 99 cent store and taped the cut ends of the plug wire to them using red and black tape. A voltmeter told me which was which, and the output was about 14-15v at 2 amps. I clamped them to my RV battery with the wires directly calmped to the terminals. Overnight the dead battery was charged to 12v, and now 2 days later, the charge is 12v with no sign of overload.<BR/> Overall cost, $1.

I have a couple of old transformer in the garage and that will work great for my situration. I leave a car in Florida for the summer and I want to keep a small charge on it without burning the battery and here is a way to do it free with what I have available to me. <BR/><BR/>Thanks - great ideal!Unknownhttps://www.blogger.com/profile/07885492174801119334noreply@blogger.com
