Aircraft Batteries - Page 2

Airplane batteries are SEALED lead acid and are not servicable. Im also pretty sure there is a age limit on them

I don't recall an age limit but it makes sense. However, almost all lead acid batteries are serviceable. Even maintenance free deep cycle automotive styles are. You need to test the electrolyte then add water and or acid as required.

I worked at a battery store for 4 years a sealed lead acid battery is non servicable because you would have to cut it open to access the electrolyte.They are used in offroad and airborne applications so that acid does not leak out of them due to excessive movement.

As I said ALMOST all lead acid batteries are serviceable. This includes ALMOST all aircraft batteries. The ones you are thinking of are for aerobatic aircraft and some experimental aircraft.

A standard Gill will have 6 or 12 vent caps on the top of it. These are unscrewed to visually inspect the electrolyte level. Then distilled water is added to the bottom of the roof of the cell. This should be done annually or at 100 hr intervals depending on the use of the plane. Been there, done that.

Batteries are currently bringing .16 a pound in south Georgia. Down from .25 a pound a month ago!

Where at, in Florida? It might worth taking the trip, from Georgia, for a good load. ;-)
Thanks

That was .36 a pound back in 2012.

LOL Crap. Totally missed the date. ;-) Thanks

It's an old thread but.. I know I do not want to be on an airplane flying with batteries bought off the street. Scrap em.
