| Item | Test Item | Specification | Test condition |
| 4.6.1 | Discharge performance | Capacity @ 0.5ItA discharge / Capacity @ 0.2ItA discharge ≥95%; Capacity @ 1.0ItA discharge / Capacity @ 0.2ItA discharge ≥90%; Capacity @10.0ItA discharge / Capacity @ 0.2ItA discharge ≥80% | Under the conditions:23±2℃,65±5%RH, stand charge first, then discharge with 0.2C to 2.75V/cell;and then standard charge, then discharge with 0.5C to 2.75V/cell;standard charge again, then discharge with 1.0C to 2.75V/cell;finally standard charge, and then discharge with 10.0C to 2.75V/cell,record the capacity @different discharge current. |
| 4.6.2 | Life cycle | Remained capacity/Initial capacity≥80% | Under the conditions:23±2℃,65±5%RH, standard charge first,then standard discharge, record the initial capacity. The battery repeat for 300 cycles as above, and calculate the remained capacity percentage. |
| 4.6.3 | High/Low temp. performance | In stand discharge, Capacity @ -10℃ discharge / Capacity @ 23℃ discharge ≥80%; Capacity @ 0℃ discharge / Capacity @ 23℃ discharge ≥90%; Capacity @ 60℃ discharge / Capacity @ 23℃ discharge ≥95%; In fast discharge, Capacity @ -10℃ discharge / Capacity @ 23℃ discharge ≥75%; Capacity @ 0℃ discharge / Capacity @ 23℃ discharge ≥85%; Capacity @ 60℃ discharge / Capacity @ 23℃ discharge ≥90%; | Store the battery for 3h under 23℃, standard charge under 23℃,then standard discharge under 23℃; repeat the first step; and then store for 3h under 23℃, standard charge under 23℃, and standard discharge under 0℃; and then store for 3h under 23℃, standard charge under 23℃, and standard discharge under 60℃; record the capacity @ different discharge temp.; Use another battery to be test as above,but fast discharge the battery in different temp. and record the capacity @ different discharge temp. |
| 4.6.4 | Storage | Remained capacity/ Initial capacity≥85% | Under the conditions:23±2℃,65±5%RH, standard charge first,then standard discharge, record the initial capacity, and then store the battery for 28 days under 25℃,after storage, standard discharge the battery and record as remained capacity, to calculate the remained capacity percentage. |

About HK Tac
We have been manufacturing rechargeable batteries, including lithium battery, lithium polymer battery, LiFePo4 battery since 2003s. At that time, Vcell Power started with only 100 workers, we only serve clients in China. During nearly 16 years development, now we have already been one of the leader battery manufacturers in China, with more than 3000 skilled workers and two factories located in Guangzhou Shenzhen Henan
