battery overvoltage

[ot1999]

If you have a 24v system,battery,  what is the maximum voltage you could introduce to

the batts. I know the battery wil dictate one voltage, the battery voltage, but what

is the flatout over voltage and what would really happen if you introduced it./??

Are you asking "At what voltage should I charge a battery?"  Well it depends on a lead acid battery it is usually 10 to 20 percent over the battery rating.  Also quick charging of other types of batteries can be accomplished by monitoring cell temperature.....there is alot of info available.

no thats not what im asking. I want to know what happens if you put an overvoltage in it and if 27 is the recom.  what happens if you put 35?

You would  boil the battery once it was fully charged if you applied 35v to it. Boiling, as you may or may not know, would eventually destroy the battery and evaporate the electrolyte.

In reality your question is too broad, what type of batteries are you refering too? The best generic answer is follow the manufacturers recomendation.

Now as an example, I run a 24 volt system using flouded lead acid batteries some 5600A/h. Now frequently my system is floating at 32V for several hours, I have no problem with this, others will. It is fair to say that my charge rate in amps verses the total battery amp hour rating is small, shall we say a trickle charge, so I do not suffer overheating problems.

But then I live off my system, am by the most part present so I control what happen's.

Lead acid batteries respond well to an ocasional deep discharge (like 50%), gee there are so many permutations. You realy need to tell us what you have or are proposing to have for any meaningfull information  for your situation to be forthcomming.

i was just wondering. its part of an overall understanding of voltage control and

what happens when things get out of bounds.
