Battery Problem?

It would be best to solder the splice.  Are you using the same guage wire as the original cable?  If not, you could be creating a safety hazard.  Make sure the new cable is not getting warm.  If it is, use a thicker wire.

Exact same wire, no heat.

I charged up the new battery and it got up to 29.0V, which is slightly higher than the other two batteries.(28.8V) I will run with it over the next few days and see what kind of charge and run times i get out of it.
The only thing that i have different at the moment is the filter has been removed. Once i get these results i will plug the filter back inline and compare results again.
Will let you know the results when i get em.

Hey Radjack,  At one time I had the same problem.  Was told that the batteries were bad after spending for new batteries, I still had the same problem.  KA sent me a new bump switch and that cured the problem..  I now have some extra good batteries if any one need them...

[Radjack]

So the results are in, and now i am more confused...
With filter out of the system:
The New battery ran for 2+ hours right out of the box. It charged up to just over 29V and ran for 2+ hours for a few days.
I then put the filter back into the system. This returns me to the original setup, but with the 3rd battery installed.
To my surprise he stills charges to over 29V and runs for 2+ hours.
I guess with those results it must have been something up with the 1st 2 batteries...
I will continue to keep on eye on Bubba, but i guess he is all back to normal. (or so it seems!)

my professional charges to 2800, then starts discharging while still in the house. the light stays green on charger. robot mows for 1/2 hour, returns to charge. is battery dead or is charger shot?

Something else to check for short run time.  I recently got Billie Back from Reform School(KA) and at least for a short time was pleased that he had been reformed.  AND THEN he started to be rebellious. Short runs got down to an hour. I did the usual checks and found nothing. Then by chance I noticed him wanting to pull off of the wire.  After cleaning the castor's found them still not free..  One of the bearings was seizing up.  Bottom line, all of the info from the high tech engineers never once mentioned to check this.  Tip... Check castor's every once in awhile.  A sticky castor makes for hard work for the little guy..

Shep - never would have thought about a sticky caster causing a short run time.  That's a new one and I think I will write it down

Whitey - it sounds like one of the cells in your battery went bad and is now low.  It is pulling the voltage down on the other cells once they get charged up.  It sounds like you need a new battery.  We have them in stock and they are not too expensive, or you can upgrade to Li by sending us your battery charger.  Li has waaayy longer life than Lead Acid and also lighter (less wear and tear on your motors) and better for the environment.

Cheers,
