It need at least one charge & discharge cycle every six months Product Performance NO.ItemsCriteriaTesting method 4.1Rated Capacity12AhRest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity. 4.2Minimum Capacity11.4Ah 4.3Internal resistance鈮?0m惟50% battery SOC state frequency of 1 KHZ ac resistance tester 4.4Short circuit protectionYesConnect the positive and negative of this battery pack through a lead with the resistance less than 5m惟. 4.5Cycle life (DOD100%)鈮?000cycleDischarge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value.

Recovery capacity鈮?0% Dimension Advantage 1. Output with high efficiency: Standard discharge current is 0.3C-1C, pulse discharge current is 3.5C for 3 seconds. 2. Good performance under wide temperature -20-60鈩? The battery structure is safe and good. 3. Good safety performance: When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion. 4. Long cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell(100%DOD). 5. It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h. 6. Low self-discharge. Less than 3% per month. 7. No pollution during manufacture and usage.
