Battery acid level and topping off?

[rcharrette]

Hi all, we've had our camper (Kodiak 240BHSL) for about 10 months. How often should I be checking the battery acid level? I popped the cover today on one of the batteries and the fluid (acid) was about 1/2" from the top. Should I top them all the way off? Do I use distilled water?

Use distilled water for long battery life. Fill each cell until the cat's eye appears. You'll noticed a distinct shape of the water when it fills to the eye.

I use one of these Lumax LX-1618 Black 64 oz./2 Quart Plastic Battery Filler : Amazon.com : Automotive. It rides along side of my batteries and is full of distilled water. It makes filling easier. I do have four six volt batteries so I need all the help I can get.

The device stops adding water when the battery is full.

These battery fillers are also available at most auto parts stores.

Thanks for the replies. I'll run out and grab some distilled water then grab the turkey baster to put it in. Shhh, don't tell the wife
