SLA replacement battery 12v 50Ah lithium ion pack for camping air conditioner
1. Standard charge of 12v 50Ah Battery
Charging shall consist of charging at a 0.2C5A constant current rate until the cell reaches 14.6V. The cell shall then be charged at constant voltage of 14.6 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.02 C. Charge time: Approx 5.5h, The cell shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
2. Standard discharge of 12V SLA replacement battery
Cells shall be discharged at a constant current of 0.2 C5A to 10.0 volts @ 23º ± 3C
3. Initial Performance Test of 12V 50Ah camping battery
| Item | Test Method and Condition | Requirements |
| (1) Open-Circuit Voltage | The open-circuit voltage shall be measured within 24 hours after standard charge. | ≥13.2V |
| (2) Internal impedance | Internal resistance measured at AC 1KHz after 50% charge. | ≤120mΩ |
| (3) Minimal Rated Capacity | The capacity on 0.2C5A discharge till the voltage tapered to 10.0V shall be measured after rested for 30min then finish standard charge. | Discharge Capacity |
| ≥49.4Ah |
