Yo, BB....you need to study-up. The amp/hr rating for a battery gives the
dischage rate, or "power" of the battery. For example, a 7 a/h battery will deliver
1 amp for 7 hours....that is the batteries rating. A good guideline for charging the
battery with out overheating it (and damage) is to use the a/h rating for charging.

BTW, I learned this technique for battery charging at the Yamaha factory training
school in 1970, and it has worked perfectly for my lifetime.

If you have a better idea on rating or charging batteries, won't you spring it on
the World post haste ?

The "flight box battery" in question is most likely a "sealed lead acid type", not a
more expensive gel cell....although it could be a gel cell, but I doubt it.

See this:

....this is probably what he has.

Here's a battery factoid you might want to store in memory. Lead and wet/acid
batteries....as well as gel cell batteries contain acid. The only difference is the acid
is in a gelled form, so it is safer and wont spill. Sealed lead and wet acid batteries
look like some gel cells.

However , the a/h hour ratings for them are the same, as well as the discharge and
charging rates.
