Some battery information

[Y-Blockhead]

I would think your battery guy would tell you to ensure you had a good water level, at least enough to cover the plates. When a battery is charged, whether it be on a charger or in your car, it releases Oxygen and Hydrogen. Water = H20.

I was taught to check to water level before charging but to only add after charging, unless the plates are exposed before charging. Then add only enough to cover the plates. This is to prevent over filling. Use only distilled water.

A little off topic but a member of Ford Barn that I have not seen on here for awhile, Willie Krash, who owned a Starter/alternator/electrical repair shop, mentioned "Battery Oil" in a thread about battery tenders.

After much research I decided to try some "Battery Oil" in my Model A Battery. I have not had to add water to my battery in ~2 years and as an added bonus it eliminated any corrosion on my battery box or cables on the battery.
