1. It has a strong navigation ability. Although the weight of medical lithium battery is only 30% of that of lead-acid battery, it has a stronger continuation ability under the same voltage and capacitance.

2. Low temperature discharge performance is good, medical lithium battery can work normally at - 25 ℃, but lead-acid battery can work normally at - 10 ℃.

3. Long charging duration: the capacity of fully charged medical lithium battery is still more than 80% in idle months, and the capacity of lead-acid battery is only about 40%.

4. Long cycle life: the charge and discharge times of medical lithium battery are more than 500, the discharge is 1C, the discharge of lead-acid battery is only 0.5c, and the service life is 300.

5. High specific energy: due to the small volume of lithium battery, but the storage capacity is more;

6. The normal working temperature range is wide: the working temperature of lithium battery is in the range of - 25 to 55 degrees, and that of lead-acid battery is in the range of 10 to 40 degrees.
