  • Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure red wire to red wire and black wire to black wire.

  • Do not mix and use old batteries and new batteries, or batteries with different brand names.

  • Please always use a smart charger (with automatic power cut-off function ) to charging NiMH battery, charging NiMH battery without an attention may cause battery explod.

  • When charging NiMH battery, please always put the battery in a wire-proof place to avoid any accident happen.

  • Please always following specification listedon our web page to charging and discharging NiMH battery.

  • For larger battery pack ( 10Ah or larger ) , please always use a smart charger with temperature sensor to avoid over heating which may cause the accident. NiMH batteries have higher energy than NiCd battery, but they have higher self discharging rate and shorter shelf life. Therefore, please always keep NiMH cells / battery pack in charged condition after using or before storing them.

  • Suggest you charging NiMH batteries and packs at least every six months, otherwise NiMH battery will reduce capacity or dead. For safety reason, we usually ship NiMH battery without fully charged. You must charging NiMH battery before use, and allow 3-5 cycles of charging and dischargingfor battery capacity to recovered.
