How to Use NiMH batteries hp laptop battery ibm laptop battery?
Although Ni-MH battery can discharge up to 500 times life, but only to have a good product and the correct charge to use. There are many chargers on the market, the most simple step-down mains charger just after the rectifier for the DC, and then direct the output to the rechargeable battery, this charger is cheap, but will charge the battery life to a certain extent effects. On the Ni-MH battery, the charging time, charge current and voltage, and battery charging when the temperature is the three elements of a good charger to charge the battery process should have improved clinical monitoring and control. First, the rechargeable battery with a constant current mode requirement, and the size of the charge current has certain restrictions; Second, the charger must be able to monitor battery temperature and control; Finally, the rechargeable battery is fully charged voltage is increased to the normal voltage state, charger should be able to monitor and terminate the charge.

1, note the temperature of charge, this is very critical. Normally, we should be 0 C to 40 C of ambient temperature batteries. Because of lower than 0 C under an internal rechargeable battery will not charge properly, resulting in irreversible decline of performance. Higher than 40 C in recharge, there will be caused to leak possible (which is why a few friends in the over-charging the battery after the hot method, the outflow of pale yellow liquid of reasons).
2, beginning as far as possible not to use nickel-metal hydride battery trickle charge. However, after the fast charging of the battery can 0.033CmA complement to 0.05CmA trickle charge (fully activated electronic). Charging the same time to avoid excessive use of trickle charge mode, this will damage the battery's characteristics, use timers to control the charging time. (Note: "CmA" in the charge and discharge process, CmA a specified size and that the battery current value of rated capacity, "C" refers to the rated capacity of the battery.)
3, is not recommended for fear of memory effect and the depth of the battery discharge, due to excessive discharge may damage the battery's characteristics, so during the discharge process should pay special attention to the power switch at the same time to avoid the battery long-term placement in a digital camera. Otherwise, the battery life will greatly reduced. When not in use within a week, from digital cameras which take out the best opening. Rechargeable battery storage on the quality of time, we can be assured Dell NF343 battery Dell D5318 battery Dell G5260 battery Dell Inspiron 9200 battery .
4, although with a rechargeable battery, the use of old and new batteries you should especially pay attention, because even with the same brand of old and new batteries can cause damage to their own digital camera-related parts of the circuit will be in danger.
5, when the long-term storage of NiMH batteries, typically NiMH battery power each month will reduce the storage of about 20%, so make sure at least every 3 months on one battery charge and discharge, this would effectively prevent the batteries from leaking, and because battery self-discharge caused by the battery performance.
