How to care for your Powertool Batteries and ways to ensure good performance:
Keep batteries clean, it is a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the device. Fully charging and fully discharging the batteries at least once every two to three weeks. Do not leave batteries unused for a long period of time. Keep batteries in a clean, dry and cool place that is away from heat and metal objects, batteries will discharge by itself during storage, recharge before use.
Differences between NiCd and NiMH
The nickel-cadmium battery (commonly abbreviated NiCd or NiCad) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. When compared to other forms of rechargeable battery, NiCd battery has a number of distinct advantages. The batteries are more difficult to damage than other batteries, tolerating deep discharge for long periods. In fact, NiCd batteries in long-term storage are typically stored fully discharged. This is in contrast, for example, to lithium ion batteries, which are less stable and will be permanently damaged if discharged below a minimum voltage. NiCd batteries typically last longer, in terms of number of charge/discharge cycles, than other rechargeable batteries such as lead/acid batteries. If stored for 3 or more months, charge the battery for 12-16 hours after taking the battery out of storage, do not store the battery on the charger.
A nickel-metal hydride cell, abbreviated NiMH, is a type of rechargeable battery similar to the nickel-cadmium cell. The NiMH battery uses a hydrogen-absorbing alloy for the negative electrode instead of cadmium. As in NiCd cells, the positive electrode is nickel oxyhydroxide (NiOOH). A NiMH battery can have two to three times the capacity of an equivalent size nickel-cadmium battery. Compared to NiCd, NiMH batteries have a higher capacity and are less toxic. However, a NiCd battery has a lower self-discharge rate (for example, 20% per month for a NiCd, versus 30% per month for a traditional NiMH under identical conditions. If stored for 3 or more months, charge the battery for 12-16 hours after taking the battery out of storage, do not store the battery on the charger.
