with proper care the 6 volt inverter batteries can last 5 to 7 years they just have to be desulfinated about once a year. any questions you can call me at 829 729 5402, my name is mcihael

Is this difficult or to complicated to put on line, could use this info.

And what are you using to do this de sulfination process?

If you have a Trace model DR invertor there is an "equalise" setting which does the job. Alternatively there are, I believe several addatives which can do the job too.

sulfation occures because of the frequency of charging and dicharging this causes lead sulfates to get hard and start to cover the plates, the worse it gets the shorter time you batteries will work they are losing their capacity to take a full charge. please do not waste tour time on additives they cause more harm than good the only way to improve performance is to turn the hard crystals back into liquid again. for more info give me a call, i use high frequency electronics to do the job and it usually takes 15 to 30 days depending on how heavily sulfated the plates are. mike

i also have relly good equipment to tell the condition of you batteries and also if there are any shorts. one bad battery will make you inverter charge to long and damage the good batteries
