Battery voltage question

50Twuncle

I have just bought myself an RC car kit with associated radio gear - this takes 8 * 1.5volt AA batteries - total 12 volts
The instructions state that either conventional batteries or NiCd or NiMh batteries can be used - but as far as I am aware, both of the latter are only 1.2volts which means a total of only 9.6volts - this is considerably short of the 12volts
So has anyone run one of these devices on NiCd or NiMh batteries successfully ?
The Tx is an ETRONIX PULSE EX2 SPORT.
As an alternative - what about recharging ALKALINE batteries ?
Is this safe ?

If depends on the kit in question really. Some kit works with a broad range, say 9v - 12v. So rechargeable batteries work ok
A lot of digital kit has a very narrow band, eg digital cameras, so rechargeable batteries don't work well.
Nickel-zinc rechargeable batteries have a higher voltage, but I've never tried them myself.

NiZn AA's are 1.6v - which "could" be too high !!

If the instructions say NiCad/NiMh are OK then why question that? Many things do perform badly if you use the lower voltage rechargeable batteries but with those the instructions normally say use alkaline.
