    I have to agree with you on this...i have had a lot of problems with these units "frying" the batteries...people are "dumping" them. The little scare we had recently with load shedding has surfaced a lots of these old units, which are now dead.

    I plan to strip one and see if i cant salvage parts from them and make a DIY power bank, using lithium batteries and a better charge unit. I do realize it is going to cost a little more however in the long run it might be a way better option. Add in a solar panel and we will be onto something.

    I have been following a DIY fella who converts cars into battery powered ones. My son is building and modify old V8's. I am gona chat to him about doing a DIY conversion to an old cheap body. Your computer will share more info than you need, if you ask the right questions. Sometime its shares more than i would like to see

    Hi Andy. My Apologies. My son interfered with my setup and plugged my lounge(load) into another source so I thought it was still running on battery. Redid the test and by charging the batteries on an intelligent charger separately, it only added an additional 20min. I have 1 x 110a/h and 1 x 60a/h lead acid battery in parallel.

    My system is working without problems but the batteries are now only delivering about 60% of their original capacity. Because I originally oversized the battery bank it means they still run all my, PC's, servers printers, router, phones and back-up lights for around 3 hours but unfortunately the coffee machine and a few other luxuries we had plugged in are a no go. We also have to disciplined about which lights are on otherwise back-up time would be under 3 hours.

    When the time comes I'll be looking at maybe upgrading to Lithium Ion batteries rather than like for like lead acid replacements but I'm not sure if the inverter built-in charger is compatible.

    A couple of the 12VDC LED tape lights I used for emergency lights in some places have a few failed LED modules along their length but they seem to be hanging in there for now.

    Lithium is the way to go ...but man the price is still a little off the mark.
