Changing battery type

[Tom-D]

But it isn't. An RG is not a dry cell (nor does it contain dry cells).

Where did you get that this was an RG?
thread drift is most often not true

follow the Link I gave know the truth.

Because that is what you enjoy.

Huh? Thread drift happens on most boards. Feel free to start and moderate your own board if you don't like thread drift.

IAW 21.93
is the change from a wet cell Gill 25 to a 12V dry cell a major or minor alteration.

3 pounds lighter at the datum line of the aircraft, changes the EMPTY weight of a 1250 pound aircraft by 3 pounds.

I do not see it as a major.
What say you ?

What aircraft?

A G25 is rated at 18 amp-hrs. The J16 is rated at 15. If the original system was certified at 15 or less, you aren't reducing the basic electrical system capacity. Having more amp-hrs in a smaller package would be better. Less, not so much.
