hi all,
I currently have a zxr250c and I would like to top up the battery, because I have noticed the levels are low.
Are the principles the same as a car battery, just add deminiralised water or do you top up with bottled sulphic acid??

Distilled/de-ionised water only.
It's the H2O that's reduced/vaporised when the levels are low.

Unless you have a hydrometer to check the SG (Specific Gravity) of the battery acid and it reads low after you top up. Hydrometers are only around $10 from most auto shops.

you shouldn't add acid to a battery after the initial charge. once the battery don't hold a charge it's time to replace it.
