User should read and follow the specifications and cautions indicated on the battery before use. Improper use may cause overheating, fire, rupture, damage or capacity deterioration of the battery. Enerthium powered by EVB360 Inc. will not be held responsible for any accidents caused from abnormal use or without following the battery limits, specifications and warnings.
Charge and discharge
Overcharging the battery for a brief time will not adversely affect the use of the battery. Do not charge for extended periods of time or over discharge as this can affect the function of the battery and cause premature failure or create serious safety hazards, If extended floating time is anticipated, use the recommended floating model specification. If the battery is not in use for an extended period of time, its own self-discharge characteristics shall cause it to discharge. To prevent this occurrence, the battery should be maintained at capacity using a voltage at 50% state of SOC.
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. 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. If the discharge time is much shorter than normal after being fully charged per instructions and specifications, it may indicate it is time to change the battery.
