General Characteristics of NiMH & NiCd Rechargeable Batteries
Charging:
Standard charging: 0.1C for 14-16 hours
Quick charging: 0.5C or total charging capacity reaches 120%(NI-MH) or 150% (NI-Cd) of the nominal capacity.(-¡÷V=10mV/cell or Tmax=45¡ãC cut-off)
Discharging:
The cut-off voltage is 1.0V at general use condition and no less than 0.75V at high rate discharging (I>3C).Do not overdischarged a battery, otherwise the performance will be damaged.
Cycle Life:
The cycle life of a battery depends on the charge/discharge condition. Generally 500 charge/discharge cycles can be expected.(0.5C-1C charged to -¡÷V=10mV, 0.5C-1C discharged to 1.00V)
Storage Characteristics:
During storage period, a battery will lose part of its capacity. But within 3 cycles, the capacity will be restored.

Battery Handling
*Do not incinerate or dismantle batteries,cell components are corrosive and may be harmful to skin and eyes.
*Do not pull on battery lead wries or connector.Excessive force on the leads or connectors can damage the welding point or other connections.
*Do not use different types of batteries in the same battery assembly.
*Do not solder directly onto battery. Please solder onto a contact pin for connection.
Charging and discharging
*Charge the battery before first application in a low current.
*We do not recommend parallel charging. Parallel charging will cause irregular charging current.
*Never short-circuit or reverse polarity in the application of battery.
*If the battery has been deep-discharged, a prolonged charging time is required to bring the battery back to full capacity.
Storage
*Please store batteries in a cool, dry place.
*After a long storage time(e.g. over six months), the battery is demanded to cycle(charge/discharge)in low current for 3 times to restore full capacity.
*Do not store large quantities of batteries in a densely packed condition when they are in a fully charged or partially charged state.
