[RE-wrenches] Followup to Surrette Battery Question

[James Surrette]

Hi Matt et al, 

Sorry for missing my que to respond. 

As mentioned, the big concerns is mineral content in the water which will adhere to the plate and "take the place" of a possible reaction site - thus reducing capacity. 

As you can imagine, water quality is a concern from both the input and output standpoint and we have an outside Environmental Consultant group review water (and air) quality 1/4ly.  We are very fortunate that even untreated/ filtered, has negligible mineral content.  I have never been in a battery plant that uses distilled water but (almost) all, I have seen, use a form of filtration / dionizing before use. 

Hard water is a definite no no!

Matt; 



I've used the watering systems for years as well, but never the tap connect. 

We have hard water here too, good to know that our distilled water mania is not in vain.

Ray, 



We sell plenty of watering systems, but none are fed from an actual pressurized tap. The "best" one uses a manual water release on top of each cap; this prevents over-filling when (not if) something sticks. 



I have never used non-distilled water in a battery, but I have replaced a couple of banks that were wrecked by using well water with a high mineral content.

I never used it, but Battery Watering Systems has used them for 
  

years. The rep I talked to thought we in the solar biz were quite 
  

cautious on this. 

I still use distilled H2O, myself BTW. 

Have you actually experienced ruined batteries from ionized or 
  

filtered H2O? 

Also, if you reread Jamie's previous response, it sounds like they 
  

aren't even using distilled H2O to build them either.

This is a majorly bad idea! Tap water usually contains dissolved 
  

minerals that will screw up battery plates, reduce or increase 
  

conductivity and generally void battery warrantees. 



Am I correct about this Jamie?

Some of the single point battery watering systems have a pressure 

regulator that plumbs right to the water tap with a small filter. 

Apparently we in the solar business are more anal about using 

distilled water than many other battery users.

Hi Bruce, 



FYI, Deionized water is commonly used in battery manufacturing and 

large motive power applications;
