1).Warranty period of two years: the date of the battery from the factory within 24 months, where the Company or the
authority of the professional testing organization determine the quality of failure are battery manufacturers, at designated
locations to give a free replacement battery with the specifications of the new; replace the battery when I While failure
to recover the battery.
2).The identification of large current discharge: new arrival in the battery, 25 ± 1 ºC temperature, fully charged battery
to the model of large current 3 times the rated discharge capacity 7 min, the battery voltage drops below 1.6V / cell,
determined to be unqualified.
3).Determine the capacity of the exception: the new battery installed in the 25 ± 2 ºC after fully charged capacity test,
in three cycles, the 20hour rate capacity can not reach the rated capacity of 90%, After five cycles, 20 hours rate
capacity can not meet 100% of the rated capacity, determined to be ineligible
4).Standard: The Company entered into force in a clear customer contract requirements, contract requirements should be
the standard;if the customer no special requirements, refer to China national machinery Industrial Standard

Are your Batteries Bad?
Batteries may still read the proper voltage with a volt meter when under charge or off charge even when they are bad. To properly test a battery it should be done with either a load on it or by using battery-testing equipment.
Batteries used in most standby equipment such as UPS systems, emergency lighting, alarm systems, etc. Will have a low voltage disconnect (LVD) that will disconnect the battery from being discharged below 87.5% of nominal voltage.
Example; 12 Volt Battery X 87.5% = 10.5 volts therefore a 12V battery will stop discharging at 10.5 volts. This also applies to strings in series.
Example; 4-12V batteries in series will produce 48 Volts. 48 X 87.5% =42V This string will be disconnected from the circuit from the LVD at 42V.
Never replace a partial string of batteries! This is not an old wives tale, it's true! When you put new batteries in a string with old batteries they will take on the characteristics of the older batteries and will require replacement much sooner and cost more in the long run. The charger will see the string as a single battery and older batteries may cause over or under charging of the new batteries causing premature failure. It will also cause the equipment to be less reliable.
