No problems with Hydrimax batteries ever. I've used them for decades. They do not need to be recycled; it's a waste of time because they don't have a memory like nicads. Good duration, and good capacity too. All types are OK with me. Just follow the rules! I've used Life in my transmitters but am going back to NiMH. I've let a Life deplete by mistake, and it wasn't pretty. I've overcharged a Life by mistake, equally ugly. Hard to teach an old dog new tricks. The Lifes did come back to almost perfect size in a month (in the ammo can). I HAVE gone to five cell NiMH with the advent of 2.4 brownout issues. Never experienced them, but I have read about others having problems. I did crash once flying an eight year old battery on a one hour charge. Stupid I am, I know. I did get three flights on the plane before the crash, and the crash came on the downwind leg of flight #4. It was really nice, it went to fail safe, the wings leveled, low motor, hit high grass, only the firewall was messed up. 12 year old airframe. I'm still stupid. I miss that plane.
