For budget friendly, I will 2nd the Rayovac batteries.
My experience is, I fly RC airplanes. I have some very small airplanes that have a small Lipo battery and it charges through the transmitter which uses 6 AA batteries. This is VERY heavy use of AA NiMH rechargeable batteries. I would some days need to recharge the AA's up to 3 times in a single day because of hours of flying the little airplanes with my kids. The Rayovacs lasted about a year and a half of the extreme use I put them through. For $5 for 4 batteries once you already have the cheap charger, you can't even beat that for alkaline batteries that you are going to throw away after they are dead.
