Battery topping up

Can anyone help me with this one....

Battery electrolyte topping up.

We have a reverse osmosis plant on site can we use that water to top up the batteries or do we need to get in
specific de-ionised water for this ?

I know the savings wouldnt be much it would just mean that we had a readily availiable source on site to tap into if required.

A couple of IEEE battery standards [450, 1375] seem mum on the subject. A call to the battery vendor may be in order.
 
Doesn't your RO system come with deionizing resin beds?

RO is specifically for relatively large (compared to ions) particles. The DI beds are what get rid of the ions. The ions are what would screw up your batteries, although it's unclear whether a battery that's old enough to need topping off is really sufficiently pristine to demand pure DI water.

Batteries are situated on diesels for starting them, from time to time they need to be topped up. Had a look and thought about this, used to use de-mineralised water for topping up, now we have RO treated water that should make things easier. But was wondering if I was missing something obvious. That was all.

Thanks for the information
 
I think the RO water is good enough.

I remember Battery vendor recommendation which says water that is good for drinking is good enough for battery topping-up too.
