Hi Everyone,
I was talking with JB about AGM batteries and the particular problems they pose with the SG circuit, the ferris wheel, and how they do not like Radiant in general. He gave me a bit of insight into how he turns AGM batts into a hybrid AGM/LAB device. if your AGM is dead you can try the following:
DO THIS AT YOUR OWN RISK, BE CAREFUL USE THE PROPER SAFETY PRECAUTIONS
1- pop the caps to expose the cells
2- go down to the local auto parts store and get some battery acid, they sell it in bulk sometimes.
3- take a small syringe and add 10 CC of acid to each cell.
4- wait a day for it to absorb the acid, then do it again.
5- do this each day until the mat does not absorb any more acid
6- drill a very small hole in the top of each cap to allow it to vent and replace the caps. make sure the battery is at zero volts.
7- REVERSE CHARGE THE BATTERY !!! yes that is what he said REVERSE CHARGE. this changes the lead plates. 10 minutes is a good estimate.
8- now drain it to zero with a load such as a resistor or dc bulb.
9- charge it with a regular charger that has a variable supply for current in the correct direction.
John said the fully charged resting voltage will be between 12.2 and 12.6 and it will behave like a standard LAB. water will have to be added peiodically as it will begin to offgass like a normal battery. this is all I was given, perhaps Chuck can chime in on this, and correct anything that is wrong with these steps.
have fun and be safe
