To avoid problems caused by incorrect use, the use of nickel-metal hydride batteries and related equipment design should consider the following matters.

Charge

A. Charging temperature

* When charging temperature should be 10 to 40 degrees.

* Ambient temperature will affect the charging efficiency. Ambient temperature at 10 to 30 degrees, the charging efficiency of the best.

* Environmental temperature is below 0 degrees, the battery is not fully within the gas absorption reaction, causing the battery inner pressure, activate the safety valve, battery leakage, performance deteriorated.

* Ambient temperature higher than 40 degrees, the charging efficiency will decline. This will cause battery deterioration, leakage.

B. Parallel Charging

When charging the battery in parallel, should fully consider measures to protect the charger.

C. Anti-polar charge

Avoid anti-polar charge. Highly charged anti-inner pressure can cause the battery to activate the safety valve, battery leakage, performance deterioration, batteries will break even.

D. Overcharge

Avoid over charging. Repeatedly over charge the battery performance will deteriorate.

(Overcharge is already fully charged battery to charge)

E. Fast Charge

* Use a specific charger for fast charging. (Or use the Universal recommended charging method) and follow the correct steps.

F trickle charge (continuous charging)

* Ni-MH batteries are not suitable for trickle charge. But in the fast-charged, free T 0.033 CmA to 0.05 CmA to trickle charge. To avoid a trickle charge the battery overcharge Ershi battery deterioration, recommended a total time timer.

Discharge

A. Discharge temperature

* Discharge temperature should be -10 to 45 degrees.

* Discharge current impact discharge efficiency. Discharge efficiency in the discharge current for the f 0.1 CmA to between 2 CmA best.

* Discharge temperature of -10 C below and above 45 C, the discharge capacity will decline.

B. Guo discharge (deep discharge)

* As will damage the battery over discharge characteristics, discharge should pay attention to cut off the current. At the same time the battery installed in the equipment transport.

C. high-current discharge

* High-current discharge will have lower heat and discharge efficiency, when for more than 2CmA discharge, you should consult Universal company.

Store

A. Short-term storage temperature and humidity

* The battery is stored in dry, non-corrosive gases, the temperature at -20 degrees and 45 degrees in places.

* The battery is stored in special high relative humidity or temperature is below -20 degrees or above 45 degrees where the battery metal parts will rust, battery leakage or organic material part of the contract. Laptop battery
