Dry batteries

[Gallachera89]

so this weekend i decided to check on a few things since my new motor will be here tomorrow and i wanted to make sure everything was good.
Had to make a few new cables, found out my rear outer wheel bearing is bad and i had to put 2 gallons of distilled water in my 8 batteries

Now i presume they have been like this for a while since i have lacked to maintain them

How much harm is done by this?
its probably been 6 months since i have checked them and i ride this thing alot.

Im really hoping i didnt hurt the batteries

Were the top of the plates exposed? If so, they are damaged. How much, only time will tell.

yah i could see fins on about 16 of the cells.. the pack still holds the voltage it should have but this makes me sad .. fml

[Gallachera89]

so what is the damage that is done? sulfate build up? i guess im confused..

The result is an unrecoverable loss of some percentage or portion of the battery's capacity. Expect shorter run time

fantastic. the plates didnt look like they were disturbed or corroded.. guess i learned the hard way

Were the tops of the plates dry? If the water level was even or just below the tops but they were still wet then probably not a huge deal. If the water level was far below the tops and the edges were totally dry then you might have ruined them.

Chances are you probably wont notice a difference.

Either way, consider it a lesson. Check the water levels frequently.

I couldnt tell how far down the water was but i know it took just over 2 gallons to fill up 8 6 volt batteries. and if my math is right thats about 11oz of water per cell . so i dont think thats much

2 of the cells in each battery had visible plate and the last cell had water over it..
so it may have been just below them but i did not pay that much attention unfortunately
