 41, the discharge efficiency?
Discharge efficiency, discharge to the terminal voltage of the release of the actual electricity consumption

and the ratio of the rated capacity under certain discharge conditions,excavator fork
mainly due to the discharge rate,

ambient temperature, the resistance to wait until the factors under normal circumstances, the higher the

discharge rate, discharge the lower the efficiency. The lower the temperature, the lower the discharge

efficiency.
42, how is the current discharge of the battery?
Means the discharge, the discharge current (A) and the rated capacity (A • h) magnification relation.
43 What is the hourly rate of discharge of the battery?
Is done by a certain output current rated capacity of the number of hours required number, called the

discharge rate.
44, how is the energy density of the battery?
Energy contained in unit volume refers to the battery.
45, lead-acid batteries using what criteria?
 
Battery Standard sub-national standards, industry standards, corporate standards at three levels. Car battery

to run the No. JB / T 10262 - 2001 industry standard.
 
46, the vehicles-3/">electric vehicle lead-acid batteries is named after?
 
The vehicle name called of lead-acid battery 6-DZM-X, where X is the suffix, X can be 8, 10, 12, on behalf of

the battery capacity. 6DZM on behalf of six single-cell battery into the voltage of a 12V electric cars

special VRLA maintenance-free battery, if it is a gel battery, the labeling method of 6-DJM-X.
 
47, lead-acid battery capacity labeling What is it?
Should prevail, that the the 0.5C2 current discharge, the product of the voltage reaches the discharge of the

battery voltage when the discharge time and current should be equal or close to the rated capacity value of

C2. For example: a 12V 12Ah battery 5A current discharge,skid steer bucket
the discharge termination voltage reaches 10.5V, the

time is not less than 140min; Similarly, a 12V, 10Ah battery voltage reaches the termination voltage 10.5V 5A

current discharge time not less than 120min. Error for 0.1Ah
 
In fact, the industry standard: 10Ah battery 5A current discharge to the termination of the voltage time shall

not be less than 120min. Enterprise product actually achieved 130 ~ 137min.
 
48, what is the ability to overcharge the battery?
 
Industry standard, lead-acid batteries to 1.2A continuous charge 48h, the actual capacity of not less than 95%

of the rated capacity.
 
49 What is the battery discharge capability?
 
Industry standards require that the lead-acid battery discharge current of 12A ± 1.2A, 2.0h continuous

discharge in a given impedance, the actual capacity of not less than 75%
 
50, what is the cold storage characteristics of the battery?
 
Industry standard, lead-acid batteries stored under the environmental conditions of -10 ℃ ± 0.1 ℃ for 10h,

the actual capacity of not less than 70%.
