The comparison of Lead-acid battery and LiFePO4 battery
| Lead acid battery | LiFePO4 battery |
| It has Sulfuric acid liquid inside, easy to pour out and corrode the battery | ABS case , safe and reliable |
| It has heavy metal-lead, pollute the environment and hazardous to health | Pollution-free |
| Lower discharge current, easy to damage battery if over-discharge. | Large discharge current |
| Short cycle life, only with 300 time and service life is about 2-3 years | Long cycle life with 10 years |
| Performance is not good under low temperature condition, it is difficult to start under -10ºC | Excellent performance under lower temperature condition |
| Easy to damage if store for long time | Can store for long time, at least 2 years. |
| Heavy weight and large size | Light weight and small size. |
About Car Battery suggestion
1. Do not connect and avoid accidentally connection between positive and negative pole with metallic conductor to avoid short circuit.
2. Do not use in deep cycle (capacity lower than 50%, electrolyte gravity below 1.200g/ml).
3. Keep safe vent-valve work properly to avoid explosion caused by valve failure.
4. Do not invert or incline more than 45 during transfer or storing.
5. Keep ventilation on during charging, no smoking.
6. Wear goggle when remove or check the battery.
7. Avoid convert connection or unstable connection.
8. Do not fill in unqualified electrolyte or water.
9. Do not operate under insufficient electrolyte condition. Semi maintenance free battery should be filled in pure water regularly.

Precautions
* Do not use other types of chargers to charge the lithium battery, you need to use a special charger for lithium batteries.
* The output voltage and current of the lithium battery charger must meet the charging voltage and current specified in the "Lithium Battery Pack Parameters".
* Do not store the battery in a humid, high temperature place;
* Do not put the battery in the fire to avoid explosion;
* Do not short-circuit the battery terminals or reverse charge the battery;
* Do not disassemble the battery shell;
* Do not touch the battery with wet hands;
* Do not squeeze or hit the battery;
* Prohibit overcharging, overdischarging, short circuit of positive and negative poles
* Avoid charging in direct sunlight;
* Do not soak in water, and the wading depth shall not be higher than 1/3 of the cabinet;
* Do not disassemble or modify the battery at will;
* When the battery is not in use, it should be fully charged and stored in a dry and cool place, well insulated to prevent heavy pressure and child contact, and fully charged every 3 months
* If damage is found after unpacking, please contact the distributor or manufacturer in time after finding out.
