Battery Water

[MFG197]

I opened the caps on my maintenance-friendly deep cycle battery and you can see the tops of the plates. It's a year old.<br /><br />To what level should I add distilled water?

Re: Battery Water

Just enough to cover the top of the plates.A little more id ok and a little less is no good.Charlie

Re: Battery Water

Fill the cells just until the plates are covered.<br />Cherge the battery. Check level. Adjust as needed. As battery discharges, electrolyte is absorbed by the plates. Charging will release electrolyte, adding to the level of fluid.

Re: Battery Water

Just covering the plates isn’t enough water. Add distilled water only. Fill to a level just below the fill tube. Think of it this way… as much water as you can get into the cell but leave a small air gap so any gases can move freely anywhere above the fluid level. If the fill tube has a slit on the side, add water just to the bottom of the fill tube. The slit is there to allow gasses to move freely.<br /><br />
