Datasheet

2) Lot release service output test is conducted by 10Ω continuous discharging to 0.9volts
- The batteries shall not leak during the service life test before the end voltage reached.
3) MAD：minimum average duration--our guarantee discharge value.
4)Normal：normal data, it's our normal daily value, battereis dicharge value are on this as base to be upper or
lower.
5. Leakage Resistance
5.1 Over discharge leakage test
Test conditions: 20±2℃ & RH 55±20%, 10Ω continuous discharge 48h.
Number of test samples: 9 batteries
Requirement: No visible leakage; No explosion.
5.2 High temperature leakage test
Test conditions: store 20 days under 60±2℃, then store 4~24h under standard environment.
Number of test samples: 24 batteries
Requirement: No visible leakage; No explosion.
6. Security Characteristics
6.1 User Drop Test
This test simulates the situation when a battery is accidentally dropped.
Test conditions: Undischarged test batteries shall be dropped from a height of 1 m onto a
concrete surface. Each test battery shall be dropped six times, twice in each of
the three axes. The test batteries shall be stored for 1 h afterwards.
Number of test sets: 5 batteries
Requirement: No fire, No explosion.
6.2 Short-circuit explosion-proof characteristics
This test simulates an external short circuit of a battery during daily handling of batteries.
Test conditions: Positive and negative terminals of an undischarged battery shall be connected
directly. The circuit shall be completed for 24 h or until the battery case
temperature has returned to ambient. The resistance of the inter-connecting
circuitry shall not exceed 0,1 Ω.
Number of test samples: 5 batteries
Requirement: No fire or explosion; Leakage is allowable.
6.3 Incorrect installation
This test simulates incorrect installation of a battery in a series application.
Test conditions: 4 undischarged batteries are used per test. 3 batteries are placed correctly
inseries; the 4
th
battery is reversed with respect to polarity. The circuit is
maintained until venting occurs or the reversed battery temperature has returned
to ambient.
Number of test sets: 5 (20 batteries)
Requirement: No fire or explosion; Leakage is allowable.
7. Expiry Date:
5 years
