How hi in volts should the pack go during charging

[jjance]

Well think about this. When the voltage goes that high you will notice a odor and the tops of the batteries become wet with acid. That's because the acid inside is vigorously bubbling(electrolysis) and blowing acid out the vents in the caps. With a mild reaction at 59v this doesn't happen. Once that acid comes out it doesn't go back in. Over time the acid becomes so dilute the battery doesn't function well anymore.

They make the battery - I gotta believe they know.

I had Trojan T1275s that were charging at 16 volts, when I asked Trojan about this they said it was normal, and not to worry.
This was with a fleet of 2004 Precedents I was working on.....well we all know what happened.
16 volts went against what I knew as being correct.
So yes they may make the battery, but that doesn't mean they know.

Perhaps they say to charge them high as they want to sell more batteries.

crazycat15, keep in mind the OBC behaves differently the first few charges after you reset it (disconnecting pack).

Until the OBC has enough data saved to start using the coulomb/energy count method, it defaults to the old dV/dt algorithm.

Sounds like a mighty big conspiracy involving all battery manf as well as the manf of the chargers as well...

Teecro You might be right. See this link.

That is old news now jjance...

That entire case has mostly been about legal maneuvers by both sides, until the motion you linked to above, it looked like Club Car lawyers were doing a good job.

That all changed around April/May of this year when Crown outmaneuvered Club Car on a "spoliation of evidence" claim that although had no technical merit or possible benefit, it was a legal victory.

Most likely Club Car will again appeal the ruling, but in the end it looks like this 8+ year old case will not be decided on technical merits.

The mitigating factors that would lead to some, not all, of the batteries used by some, not all, of the golf courses to improperly charge the batteries were never discussed or apparently relevant to the contract in dispute.

One does get the wrong idea about the OBC by reading the "contractual terms" being argued in the claims, but unless 100% of all batteries used on those carts everywhere failed, which was not the case, means the OBC does work the way the engineers at Lester designed to work.

Perhaps the guy that knows more than the engineers that design batteries can explain better or talk about what "we all know what happened" since nothing on the Club Car lawsuite has to do with overcharging batteries (the topic in this thread).

Your right Sergio but the comment was made in reference to Tecro comment

Sergio, i have read that this might be the case. So im going to run the cart for a while and recharge it a few times to see how it reacts. Thanks much i appreciate the input

Love it. Trickery and deceit will get you anything
