Q. Why should I choose NEXcell NiMH rechargeable batteries over other types of batteries?
A. NEXcell NiMH batteries are rechargeable up to 500 to 1000 times which means you can save money comparing to rechargeable alkaline of 50 recharges and non-rechargeable batteries. Our NiMH batteries are also designed for power intensive applications such as digital camera, the batteries will maintain a high and consistent voltage during its discharge cycle, NEXcell batteries have lower impedance than the other brands in the market.

Q. What is the "no memory effect"?
A. The traditional NiCd batteries would develop memory effect problem if the batteries are discharged at a fixed depth of discharge and then recharged frequently before they have fully drained. "No memory effect" means that you can charge the batteries anytime you like without worrying their performance and battery life. NEXcell NiMH batteries have no memory effect.

Q. How long a rechargeable battery will last?
A. The charge holding time of an unused rechargeable battery at room temperature is about one to three months depends on the storage temperature. The best storage temperature range is 10 to 20 C. NEXcell batteries are rechargeable up to 500-1000 times depending on discharge and charge current and working condition.

Q. How many times can I recharge my NEXcell NiMH batteries?
A. The answer is between 500-1000 times. As a general rule the higher the discharge and charge rates as well as the deeper the discharge between recharges the fewer charge/discharge cycles will be obtained.

Q. How can I help my rechargeable batteries last longer?
A. 1) Use only "A" grade charger and follow the instructions come with the charger. Cheap "B" or "C" grade chargers will damage your batteries and shorten their life. 2) Overcharging will also damage your batteries and shorten their life. Use a high quality "smart charger" to solve this problem.. 3) Make sure not to drop your NiMH batteries which will cause unrecoverable damage.

Q. Why should I pay more for the "higher battery capacity"?
A. The capacity of NiMH batteries is rated in "mAh" (mili-ampere hours). If the discharge current is fixed, for example, 1000mA, the higher capacity means the battery will last longer.

Q. Do I need to charge the new batteries before using them?
A. Yes. You may need to cycle them several times before the NiMH batteries reaching their peak performance.

Q. What is conditioning?
A. The conditioning process is used first to drain the charge from the batteries and then recharging them. Conditioning can allow batteries to perform at their best standards and eliminate the memory effect of NiCd batteries. For NiMH batteries, conditioning is recommended for every ten to twenty charges.

Q. Is it normal that the batteries get warm when charging the rechargeable batteries?
A. Yes. This is because the increase of internal resistance and less energy conversion efficiency from electric energy to chemical energy. We recommend you leave the lid open during charging to reduce the heat build up inside the charger.

Q. How long will the rechargeable batteries hold their charge?
A. NiMH batteries will self-discharging even left unused. They will lose 1-2 % capacity per day. The self-discharging rate is depending on the storage temperature. Store your batteries in a cool dry place to minimize the self-discharging effect. You need to recondition and charge the batteries several times to restore their peak performance. NEXcell NiMH batteries do provide a much longer shelf life compare to almost all other NiMH batteries.
