Ansmann NiMH batteries have been developed especially to meet the demands of photography but will perform well in all of your high drain, energy-loving applications including toys, radios, flashlights and MP3 players. They will ensure longer operating times for your digital cameras and flashes and are fast charging, highly reliable, leak proof, and long-lasting. Environmentally safe - NiMH batteries may be disposed of with regular trash. No memory effect means batteries can be recharged at any time, even when only partially drained. Always charge regular NiMH batteries before first use.
