1、Energy density: Lithium battery has 5-7 times higher energy density than lead-acid battery, meaning it stores more energy for the same weight.
2、Size: Due to its high energy density, lithium battery has a smaller size compared to lead-acid battery, making it easier to carry and install.
3、Lifespan: Lithium battery has a longer lifespan of 8-10 years, compared to 2-3 years for lead-acid battery.
4、Weight: For the same capacity, lithium battery is 3-5 times lighter than lead-acid battery.
5、Self-discharge rate: Lithium battery has a lower self-discharge rate of 5%-10% monthly, compared to lead-acid battery which has a higher rate.
6、Operating temperature range: Lithium battery has a wider operating temperature range of -20℃~60℃, compared to lead-acid battery which has a narrower range.
7、Charging speed: Lithium battery has faster charging speed, taking about half the time to fully charge, usually within 4-6 hours.
8、Environmentally friendly: Lithium battery contains no harmful substances such as lead, mercury, and cadmium, making it environmentally friendly during use.
In conclusion, lithium battery has higher energy density, smaller size, longer lifespan, lighter weight, lower self-discharge rate, wider operating temperature range, and faster charging speed compared to lead-acid battery.
