Battery Refill distilled vs. rain water

Now that the weather has cooled down our solar panels are giving us

far more energy than we need. This causes the batteries to remain at a

charge over 100% all the time. This also means the batteries are going

through more water due to the excess energy. I needed to refill the

batteries and didn't want to buy a bunch of distilled water in plastic

bottles. Instead I tested the difference between our rain water we

have caught and distilled store bought water I already had on hand. It

turns out our rain water has about 8 PPM while our store bought

distilled water as at 11 PPM. Our rain water actually has less

particulates than Shure Shine store bought distilled water. Needless

to say I filled my solar batteries up with rain water and have no

plans to purchase distilled water gain.
