I have a 7 Ah unit and have been using it for years. Not bad for what it is after all, deep down it's just a 12V lead-acid battery. But one fine day it just oetppsd charging. At first I thought the battery was dead and so I went to Radio Shack and bought a new one for $15. It isn't hard to replace and all the lights lit up and everything, but still no charging. Then I did what I should have done in the first place measured the output voltage of the 15V power adapter. No voltage to speak of. Then I tried to repair the adapter itself but it turned out that one needs a screwdriver with a triangular tip to open the protective cover of this thing!! No hardware store in my area (and I checked quite a few) had such an outlandish screwdriver. For that matter, I couldn't find a replacement either. It is hard to find a 15V adapter; most power supplies out there are 6, 9, or 12 volts. In summary, I'm left with a functional main unit and no easy way to charge it up. So, buyer beware: if something stops working you may well have to buy a brand new one.
