AA Akaline vs rechargeable

Just bought a Futaba 10J which came with 4 AA alkaline batteries. This is my first radio with such batteries. I have used the radio for about 5-6 hours. The voltage still reads 5.2. The manual says to set the warning voltage at 4.2

I will never go that low which leads me to my question:

Why would I ever use rechargeables when AA alkalines are so cheap and readily available? I was and am still puzzled. The capability of just plugging in 4 AA when I need to is very convenient.

Environmental, rechargeable just makes sense and in the long run saves money along with environment.

When I had a radio that used AA cell I would keep Alkaline set as emergency back in my tx case. Now I use nothing but LiPo/LiIon packs when ever I can..

1) Dead AA's go to landfills.
2) Dead rechargeables get charged.
3) When rechargeables are no longer chargeable, they get recycled.
4) If I forget AA's at home, I have to buy more on the road.
5) I won't forget rechargeables at home unless I forget my transmitter.
6) If I forget to charge them, I can do it at the field.

Short term the AA's cost less money out of my pocket, but long term rechargeables are all-around better.

Our county recycles alkaline batteries. I agree that over the long haul the price is cheaper. The battery that Futaba is recommending costs like $40.

If you are currently using alkaline AA cell I would look into getting Eneloop 2,000mAh cells...
