3. Deep cycle lithium battery pack 12V 25Ah Safety Test

No.	Items	Standards	Testing Methods
1	Vibration Testing	The appearance of battery should not leakage, break or explosion	Fix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.
2	High Temperature Discharge Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than 255mins	Place a full charged battery under the environments of 55℃ for 2 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
3	Low Temperature Discharge Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minute	Place a full charged battery under the environments of -20℃ for 15-24 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
4	Constant Humidity & Temperature Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than180mins	Place a full charged battery under the environments of 40℃ and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 0.2C to the cut-off voltage.
5	High & Low Temperature Storage	The battery should be no remarkable breakage, distortion. And charge/discharge normally	Place a full charged battery in a oven with 55±2℃ for2 hours, then keep it under 20±5℃ for 4hrs, then place it in a oven with -20±2℃ for 2 hours, then keep for 4 hours under 20±5℃, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times

4. Storage & Transportation

Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
The battery should be stored in 50% SOC during transportation.
The battery need to be charged every 6 months if out of use.
Keep the battery against dropping, turning over and serious stacking during loading.

5. Warning & Tips
Please read and follow the specification and caution remarks on battery surface before use the battery. Improper use may cause heat, fire, rupture, damage or capacity deterioration of the battery. Shenzhen Topband Battery Co., Ltd. Describes is not responsible for any accidents caused by the usage without following our specification.
