Rechargable Batteries ???

So I use alot of AA batteries. Mostly in my animation projects. I was curious about how standard Alkaline or Lithium based AA batteries compare with rechargable AAs. I have some Nickel Metal hydride rechargable AAs and a charger. I see that the Rechargeable are listed as 1.2 volts compared to the others which are 1.5 volts.

Is there an amperage difference ? Is one better than the other for powering small motors ? What about powering receivers ?

I think the biggest issue would be transmitters where 4 alkaline batteries are 1.5 times (1.7 when new) 4 giving at least 6 volts vs 1.2 rechargables giving 4.8 volts. Output power could be greatly reduced with the lower voltage.

LGB’s bubble car likes fresh alkalines for this reason, motor turns too slow with rechargables.

I have a lot of dead AA Nimh batteries. If you don’t charge them regularly they die. I carry mine home from Florida to charge every month.
