Low self discharge AA NiMH battery. Great for transmitters, fuel pumps, glow starters or other low discharge electronics that you want to use over several months or years without having to recharge.
Low-Self-Discharge NiMH batteries are a new technology that prevent the battery from slowly losing it's charge over time. In fact these LSD batteries can stay charged for over a year without losing more than 30% of their charge. Normal NiMH batteries would lose nearly 100% of their charge over 12 months.
