Battery operation instruction
Discharging current
The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the over sized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.
Electric discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specification book stipulated.
Storing the Batteries
The battery should store in the product specification book stipulation temperature range. If has surpasses above for six months the long time storage, the discharge capacity will decrease sharply.
Period of Warranty
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as discharge, ambient temperature, are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. Please change the battery in time.

New Porformance for Ready to Use nimh battery
Charging once, standby for two years: After the battery is charged for half a year, the power is retained for more than 90%. After a year of holding, the power reserve can be more than 85%. After two years of suspension, it will remain above 80%, eliminating the need for ordinary nickel-hydrogen charging. The battery has no trouble for a long time, really charge once, spare for two years!
