    just had two weeks in France, every was working fine till the final morning when we notice a red light on the control panel indicating the leisure battery was dead! Once we got home we discovered the battery(banner) was more or less dry, so we topped it up. The following weekend we discovered that as soon as we started to use anything electrical the leisure battery started to lose charge quickly. To solve the problem we hooked up. We replaced the battery, again banner but we still seemed to have the same problem. We have a 100w solar panel, which seems to charge the battery but as soon as night falls power seems to drop. Could it be the regulator? How do we test this? Any ideas or help would be gladly received.

    How low is the battery voltage dropping too?

    12.2 after a couple of hours use! Turn everything off and went out. The following day was sunny and by late afternoon we were back up to 13. We can't understand why a new battery won't hold a charge. We're not heavy users.

    Well 12.2 is flat and 13 when the sun is on the solar panel is not telling you anything really as you are only measuring the voltage from the solar controller when connected to the battery so the battery could be anything between 12.2 and 13 in theory. you need to let the battery rest with no sun on the panel (i.e. dark) and then see what it reads, 12.7 would be full.

    Its very possible that you are not getting enough charge in during the day and the battery is permanently flat. Might be a good idea to give it 24 or 48 hours on hook up and see how it performs.
