4.Testing:

 

A   4.1 Temperature  and  humidity: Unless  otherwise  specified  elsewhere,  tests  shall be

conducted at ordinary temperature (20±2℃) and ordinary humidity (65±5%RH).

 

A   4.2 Storage of test specimen batteries:  Specimen  batteries to be tested shall be kept at

the ambient  temperature of 25℃ or  below and at the relative  humidity of 75% or

below.

 

A  4.3 Measuring instruments and devices:

Outer micrometers  specified inJJG26-95, dial gauges specified in JIS B 7503,

and   vernier  callipers  specified  in  JJG30-92  or those  having  equal  or  better

accuracy shall be used.

 

.   DC voltmeters: The tolerance shall be ±0.01V and the input resistance rating shall

be 10MW or more.

.   Load  resistance: Load   resistance  shall  include  resistance  throughout  external

circuits, and its tolerance shall be ±0.5%.

 

A  4.4 Test methods:

.   Dimensions:  Dimension   shall   be  measured   with   instruments   specified    in

Subparagraph  4.3(1)  above,  provided   that  either  one  or  both  sides of   such

instruments  shall  be  insulated  in  measuring the overall  height   of  the  batteries.

 

.   Appearance:   Appearance of  batteries  shall  be  inspected  by  visual  means.

 

.   Open-circuit  voltage: Test specimen batteries shall be kept  for 8 hours  or longer at

the ambient  temperature specified  in Table 1, and  then  the voltage  between  both

terminals  shall be  measured at  the same ambient  temperature with  a voltmeter as

specified in Subparagraph 4.3(2).

 

.   Closed-circuit voltage: Test specimen batteries shall  be kept for 8 hours or longer at

the  ambient  temperature  specified  in  Table 1. and then the voltage between  both

terminals  shall  be  measured  with  a  voltmeter as specified in Subparagraph 4.3(2)

while  the  specified  load  is connected  between both terminals at the same ambient

temperature  as  specified above; provided that the measured value shall be based on

meter reading taken 8 seconds after the circuit is closed.

 

.   Service  life: Test  specimen  batteries  shall  be kept  for 8  hours  or  longer  at  the

ambient temperature specified in Table 2. and shall then be continuously discharged

at  the  same  ambient temperature  and  through  the  specified load resistance. The

discharge  shall  be  continued  until the  terminal voltage of the test specimens falls

below  the discharge  end-point  voltage  of  2.0V,  and  the  time  during which the

terminal  voltage has  been maintained  equal to and above  the discharge  end-point

voltage shall be taken as the service life.

 

.   Service  life after  high-temperature  storage: Test  specimen  batteries, after having

been  stored at  the temperature and period specified in Table 3, shall be kept for 12

hours  or  longer  at  ordinary   temperature  (20±15℃)  and  at   ordinary  humidity

voltage  falls  below  the  discharge  end-point  voltage of 2.0V,  and the time during

which  the  voltage  has  been maintained equal to and above the discharge end-point

voltage shall be taken as the service life.

having been stored at  the temperature, humidity and  period specified in Table 4.

.  Self-discharge:  Test specimen  batteries which have been stored for 12 month at

the ambient temperature of 20±2℃  and at the relative  humidity of 65±20% shall

be   tested  for  service   life   in   accordance  with   the    method   specified   in

Subparagraph 4.4(5).

Self-discharge shall be determined in the following manner:

 

 

X1 –  X2

Self-discharge rate (%) = ————-  x  100%

X1

X1: Average initial discharge life of batteries of the same lot

X2: Average discharge life after storage
