Well went and had a look at those old 600AH sonnenshein AGM batteries today and put 2 litres of rainwater in each cell so the glass mats in each cell can become moist again.
Now on measuring open voltage I did find each cell on around 2.7-8 volts each and the total pack voltage was 32 volts. So these may be a lost cause but nothing ventured nothing gained is the old saying.
So for ease I pulled out the original 24 volt mod sinewave inverter that came with the farm connected that up and found my sander did work at first then not after that. Tried my vacuum and no go so used an old 100 watt light globe which did work and I'll leave going all night then check the voltage in the morning.
I do think a few deep discharge/recharge cycle will prove good for them and my old Kipoint inverter will come down from the shed to be used.
The main goal of these old batteries is to supply lighting for the shed so if it does workout it will be less load on the house inverter a Selectronic SA32 that has been going since '04.
