Re: Batteries
 

Gene,
Interesting results...It appears that the 2005 batteries do match the power curves in the documentation so it is surprising that the 2004 batteries produce better performance than the new batteries. It is pretty odd. One of our parents is working with SnapOn Tools on battery check instruments and brought in an impedance checker that they make. We ran impedance checks on all of our batteries (some more than 4 years old) and the recent batteries even back to 2001, maintained their specified impedance. The oldest battery we have still only measured about 20 mOhms after all this time.

We are also having unusual battery drops but it might be due to our motor setup. We will test out the batteries to verify the 2004 2005 differences.

Re: Batteries
 

i was just wondering becuase are old batteries 2003, 2002, are not up to pow. I was wondering would a deep cycle help the battery keep its power again.

Re: Batteries
 

It is unlikely that battery conditioning will help with these batteries. They have a very defined charge/discharge lifetime (about 400 cycles as I remember) Older batteries will certainly be close to that number if you practice and use your old batteries often. Lead acid batteries do exhibit other problems but I don't think you are having any of those issues.
