PoPRC Wrote:I was given 12 AA rechargable batteries. The thing is these batteries are NIMH 2400mah 1.25V. I charged them up and put 8 of them in my JR XR3. The voltage reading on the radio was 11.0V. So if I put 4 in the car I get 5.0V. Are these ok to use or do they have to be 1.5V batteries? Will they weaken my signal from Trans to receiver? I would like to use them cause the charger I have is ultrafast and charges the batteries in about an hour. Any advice would be greatly appreciated.
Thanks,

Likewise, the XS3 radio works great down to +/- 9.0 volts (about) then starts beeping at you.
In the RX pack, they are at least as good as 4 AA dry cells just on capacity alone. AA alkalines drop to 1.2 volts almost immediately when you run the car, and get lower with every minute. The rechargeables drop to the lower voltage and stay flat on voltage until they discharge to "dead" levels.
The best answer for the car, is the 5 cell hump pack at 6.0 volts. It's worth the money. But rechargeable aa's are still better than Duracells.
