I got he special charger. It was only 10 bucks. The only bad thing is that it takes 8 hours to recharge the battery.
Thats not the bad thing.. thats the good thing. Most NiMH Rechargables take 15 hours to charge from dead. Your battery will never be lower then 80% unless you leave your gun on over night so it will only take you 2-3 hours to top it off. If you shoot 2-3 cases a weekend, you could top it off once every other week. But to be safe, I would top it off every weekend before you play. With that charger, I wouldnt be surprised if you got 16k shots per full charge. The only thing you have to worry about is drastically over charging. That will shorten the life of the battery. Thats why I suggest a radioshack tester. Charge it good once and see what the charger says, then charge it to that point every other time. That battery will last you 1k charges if you do that.
