Visual Check |
-
- Specific gravity 1,280 Kg/dm3
|
|
- 1. Does the battery leak ?
|
- Yes - Continue with A2
- No - Continue with B
|
- 2. Is external damage visible in vicinity of leak ?
|
- Yes - Reject claim ascertain cause of ge
- No - Claim justified
|
- 3, Are the cells evenly covered with acid ?
-
-
|
- Yes - Continue with B
- No - Reject claim not manufacturing
- detect
posible causes over charging
|
- B
Specific gravity test
- Funtioning batteries should have the same spesific gravity
in all cells. Maximum permitted tolerance in all 6 cells ± 0.05
kg/dm3
|
- Please Ensure That :
if the speciifx gravity of the acid is less than 1,240 at 27º
C, the battery is charged before further testing !

|
- Procedure
|
|
- 1.260 - 1,280
|
- Fully charged
|
- Proceed with test
|
- 1,200 - 1,240
|
- Half charged
|
- Charge recommended
|
- Lessthan 1,180
|
- Minimal charge
|
- Charge immediately
|
- Lessthan 1,120
|
- Discharged
|
- Charge immediately
|
- 1. One cell with low specific gravity
- Example : 1,260 - 1,260 - 1,150 - 1,260
- 1,260 - 1,260
|
- Yes - Claim justified
- No - Continue with B2
|
- 2. Two adjacent cells with low specific gravity
- Example : 1,260 - 1,170 - 1,170 - 1,260
- 1,260 - 1,260
|
- Yes - Claim justified
- No - Contiune with B3
|
- 3. Is the electroyte discoloured (drak brown) and / or is
- there evidence of excessive water
consumption
-
|
- Yes - Reject calim - damage caused by overcharging - test
voltage regulator on
vehicle
- No - Contiune with B4,B5, or B6
|
| 4. If the
specific gravity is less than 1,120 kg/dm3 in all
cells anclor a milky discolouration of the electrclyle is
present, charge the battery in the charge acceptance at
least 1/20 th of the nominal capacity |
- Yes - Charge battery - if the specific gravity is less than
1,240 when the battery
- is
fully charged there is no fault, the battery has ercded due to
ageing,
-
reject claim
- No - Reject claim - damage caused by deep cycling
|
| 5. If
the specific gravity is uniformly less than
1,200 in all cells, charge the battery is the
charge acceptance at least 1/20 th of the
normal capacity ?
|
- Yes - Charge battery - if the specific gravity is less than
1,240 when the battery
- is fully
charged, there is no fault, the battery has eroded due to ageing
->
-
reject claim
- No - Reject claim damage caused by insufficient
charging. check vehicle
- electrics
i.e. voltage regulator, alternator of fan belt.
|
| 6.
Specific gravity equal in all cells, but above 1,240 kg/dm3 |
Proceed
to test C |
- C
High rate discharge test
- This test should be carried out if the specific gravity is
abouve 1,240 kg/dm3 otherwise charge the battery first
|
 |
- Failure to reach required voltage under load of colapse ?
- For discharge testers with variable
- resistances the following test applies :
|
- 10 V at specific gravity of 1,280 kg/dm3
- 9 V at specific gravity of 1,240 kg/dm3
-
-
|
| Subject
the battery to a load equipment to 3 x .... capacity for 10 seconds
(i.e. 12V/45 Ah at 123 A) During the test load and the resulting voltage
must both remain at the given values above. |
- Yes - Claim justified
- No - Battery in good condition
