Angry stuid radio

I just bought a new pack of batteries for my radio (JR xr2) on friday. When I first put them in it showed on the display screen it had 12.4 volts. After about an 45 minutes of use it 's dropped down to 11.3 volts. After i buy a new pack of batteries they only last in my radio for 3 hours if i'm luckly.Is it normall for the batteries to be drained so quickly?

Alkaline batteries will not give you much runtime on a high-drain device like a radio. Pick up some NiMH rechargables (available at pretty much any store like Wal Mart, Target, etc.) and you will save a lot of money on batteries.

Thats normal going from 12.4 to 11.3 volts after 45 minutes of running if they are alkaline batteries. If you worried about your AA batteries, get some new 2100 AA made from GP

GP's are good. I have the 2000mah Nimh batteries and they last pretty long. They also have 2100mah batteries and ou can get them overseas. Team Orion makes some 1800 mah batteries but they are hard to find. Just make sure that whatever rechargable batteries you choose, that you recharge them the night before a race.

My question is: What is the low voltage alarm set at for this radio?

On my Futaba Radios, the low voltage alarm is set at 8.7 volts. I like to change the batteries when they are in the low 9's. (A fresh Alkaline will be 1.58-1.61 volts per cell)

For radio's that have rechargables, just top them off the evening before each race day.

70mph...I see that you're in Edmonton...

Your best hookup for batteries is likely going mto be Walmart...

a 4-pack of Energizer 2100mah NiMH batteries will run you $15.64 Cdn if they hold the same pricing strategy as here in Ontario...

I'm running those in my R-1 and get LOTS of run-time between charges...and if they'll last in an R-1 they'll last FOREVER in an XR2
