Can use distilled water?

[Paladin]

Hi , just wondering if it is possible to use bottled distilled water as battery water?

If I am not wrong those battery water selling in the petrol station are actually just distilled water right?

 

Anyone using distilled water as replacement?

[Toalson]

Yes they are the same..... I hv friends who use the distilled water from watson as alternative (cheaper). So far I did try bf on my previous ride but right now lazy n on maintenance free batt thus no need.

just take note....those found in petrol kiosk...label as battery water...ve very lite acid in the content(chk & found sumtimes ago)...

those sold in supermarket as distilled water....r drinkable(pure distill)

 

u can use distilled water for ur battery...DUN use tap water...

Depends how much you trusted the source of distilled water. They can be by-product of boiler plant but if their bottling pipe are not adequately anodised, the distilled water is only pure at its point of condensation.

Theory wise, can use. But better don't take any chances and use those battery water instead. After all, how much $$ can you save by using bottled distilled water as compared to battery water?

Highest quality of distilled water are sold mainly at pharmaceutical shops. You need only to add distilled water DO NOT try to add diluted suphric acid.

Actually a lot. If you got a resistance tester. Pure water is supposed to have resistance of 18-megaohms. Means no salts in it.

 

BTW, pure water is not very pure. It is acidic in nature which explains why you cannot use it purely in your coolant system. The acid is actually in the form of carbonic acid from dissolved CO2 from the air. pH of pure water ranges from 5-6. Don't let people fool you into thinking pH of water is 7.5

I only know battery water costs about $1 per bottle. How much does good distilled water costs? Also where can I buy it from?

Battery water is best left for battery. You can't take chances with that unless you got means to test if the cheaper distilled water from NTUC Fairprice, Guardian Pharmacy or First Choice meets 18-megaohm. Maybe I will do this for you guys. I got equipment.

I post the question because I remember having reading somewhere that battery water is actually distilled water.

 

Actually a 1.5L ice mountain is selling at 65cts in NTUC I think, while a 1L battery water is selling at $1.30 in Shell petrol station.

[Paladin]

Very interesting... so what equipment do u use to test the resistant?

Please post the result here.

Yes distilled water or de-ionised water is the way to go. Have been using rain water for donkey years until I give up my car 10 yrs ago.

Tap water is actually Ok, but because it is being piped by metal pipes and it also contain chlorine therefore it is not de-ionised and have too much other foreign particles.All these are in a way harmful to the electrolysis process inside the battery

U may wan to try....dip a few drops of battery water on a concrete flooring...u will see tiny bubble bubbling up....as I mentioned earlier...contains veri lite acidic..

i tot DI water is 18-megaohms? DI water and distilled water same meh?

The wordings on the battery water bottle gives me the impression that its more than just simple distilled water. (Maybe its just marketing) Can't remember the exact wordings, but I'd rather use battery water instead. Anyway, 1 bottle can last a long time, so the costs saving compare to buying distilled water at NTUC isn't much.

Not advisable to purchase from Shell store too Exp. Me brought from supermarket cost only $0.50 / Ltr

[Octopus]

Thanks for the tip. By the way, which supermarket?

 

I remember seeing something like $0.50 per bottle selling at Giants few months ago ...... guess I should wait for the clearance sale then buy.

If DI water and distilled water are pure enough, they are almost synonymous. Both should be 18megaohm water.
