Yes, and cycling the batteries is actually good for them with the new charging system!
They get STRONGER with repeated discharge/charge cycles! I had some new Radio Shack
NiMH batteries, they gained like 20 to 25% more run time as I used them. It is a John Bedini
charging system, works fabulously :D

This works on up to 100AH batteries, it will be to rejuvenate them. They make bigger units, for
larger banks and higher voltages also. I have spoken to Rick Friedrich on the phone a few times,
he is a good and honest man and great to deal with. He has even encouraged me in my STG Venture,
he knows the technology WORKS and is very supportive.
