2. Deep cycle lithium battery 12V 15Ah reliability test
No. | Items | Standards | Testing Methods |
1 | Internal Impedance | Impedance ≤50mΩ | Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test . |
2 | Nominal Capacity | 15Ah | Rest for 0.5~1 hour after fully charge, Using electrical loader to connect with the battery output port, and discharge with constant current 0.2C till it can’t discharge. Do the cycle three times, if there is one time that the discharge time is equal or more than 285minute , you can stop. |
3 | Short circuit protection | No load ability after short-circuit .comeback capability of loading after remove the lead away, | Short the pack with the lead (<50mΩ). If remove the lead away, connect the electronic loader with P+, P- of protection board again, so load ability comes back. |
4 | Allowed Maximum continuous charge Current | 15A | charging with 15A for more than 0.5h and the added temperature of battery pack less than 10℃. |
5 | Allowed Maximum continuous discharge Curren | 15A | Discharging with 15A for more than 0.5h and the added temperature of battery pack less than 10℃. |
