Ques. How do I maintain my rechargeable battery pack?
Ans. When you receive your new NiMH rechargeable batteries or battery pack, you must charge them fully before the first use. They may show full voltage and power required to operate your device, but charging before you use them the first time is still very important. Please note that for new NiMH rechargeable batteries, it can take from three to five charge and discharge (use) cycles before they reach their peak performance. At normal room temperature, NiMH rechargeable batteries will generally lose about 1% of their charge per day. Higher temperatures will increase this loss, and lower temperatures (40-60F) will reduce this daily loss. This "shelf life" is less of a factor if you use them within the first five to ten days after they are charged. One of the best ways to ensure that your NiMH rechargeable batteries will last as long as possible is to use them often. The more they are charged and used, the longer NiMH rechargeable batteries will last. Whether discharged or not, NiMH rechargeable batteries should be charged at least every sixty days.
