Settings for Exide Forklift battery

[BioPower]

I am working on improving my setup with the AC so high temperatures will not be an issue when there is sufficient sun. The price of a small AC that draws 500 or 600W max is not much these days, then it should be no problem to keep the batteries in an environment of around 22 degrees. That should keep the batteries near 25 while charging, at present, I have all my solar equipment in a shipping container which is much harder to keep comfortable. One option I could do for now is put the batteries in an insulated box and let the vent fan draw air out of the box and have a inlet pipe directly from the outlet of the AC. Last summer I had one day that the Midnite CC recorded 45 degrees.

Seems like golden rule is never ever ever put anything but distilled water in a battery . That battery dealer either doesn't know much or has some very pure water !

Or wants to sell more batteries. That IS his business.

Definitely return those cells to their retaining steel tub!
As resthome stated you will get battery damage otherwise.
There is a exide dealer in brisbane mate.
Have you tried them?
I have some old 1330 amp exide cell tubs with the charging parameters on them.
Not perfect but better than nothing.
I am in qld and have my cells under cover with no a/c on them.
Temp rarely goes over 30deg.
Pm me if you want those charge levels.
It would give you a starting point.
Your batteries would be heavier and most likely take more and a tad higher charging.

It would be good to get those charge settings, should be no reason not to post them for everyone to see.

The battery arrived Friday afternoon and I managed to unload it in one piece and get it connected then. So it is still in its steel box, it was sitting on 50.7 volts when I got it. It has not been below 50V yet according to the Midnite monitoring, state of charge has only been down to 87%. The people I bought them from are waiting for the factory in India to send them the settings, I will give them a call today to see if there has been any progress.

That metal ruler on top of the batteries- yikes !

All the terminals are insulated so it is not as bad as it first appears, it is resting on the case so it is not in contact with the batteries. But you are right it is not a good place for it.

Was a Nice Ruler !! Let me tell yar the close call !!

There was no close call all the terminals and bolt heads are fully insulated, you could throw the ruler into the battery all day long and it would not short.

There is hole in the top of the insulator on the bolt head just large enough for a meter probe to fit in, there is no way you could get the ruler to make contact.

I get it but scares me all the same - when I am using metal tools like rachets or wrenches to work on my batteries I try to be extra careful just in case !  The thought of all that current running through a metal tool and it getting red hot - well keeps me conscious ! I was messing around with some small agm  batteries ( like 30 ah or less ) once and was using some bare copper wire to buss all the terminals together to put a trickle charge in  and accidentally  touched the wire to other terminal and got a nice burn mark along my hand instantly  !

I have had a similar experience with 18650 Lithium batteries, put one in backwards and got a nasty burn.

The manufacturer of the batteries this topic is about has done a very nice job with o-rings on the interconnector lugs to keep them safe from corrosion and the insulation on them and the bolts. They really have improved the safety in a big way, if it makes you feel any better I did hesitate and think is something better to use for scale in the photo, but there was nothing at hand other than the ruler. If this was a battery with lead links or similar I would never have put the ruler there.

Anyhow if anyone else wants to have a shot at me about the ruler go ahead I know it was safe and as far as I am concerned the subject is closed.

I didn't know all those terminals were insulated like that . That is a great . never seen that before .

I like the work they did to make it as safe as possible....

HOWEVER ....  the cables that connect to the ? buss bar(s) do not appear to be or have a shrink fitted covering right to the final connection ie look at the blue Cable covering near the 150 mark on the ruler..

still a potential  'short-able connection'... just needs one of those cheap plastic/rubber covers used on cars etc these days..

I was NOT having a shot @ you Sir.
I was making a Joke !!
We have all been there & it's why we know how to treat POWER
I use Hot gloves on 600Vdc trolleys at one time in my life & hot sticks up service poles / buckets .

It was typed & posted for a funny only .



Im now opening up EV battery packs of 200 to 540 VDC ni mh  or Li ion  or Li Po  cells .
MAN you need to be alert & with it ..

Sorry if I pd Ya

[BioPower]

Sorry VT I took your comments the wrong way, it is difficult to see the smile on your face when you type those kinds of comments.
