2. Lithium iron phosphate battery. Its advantages are: electric capacity, power, life than the "lithium-ion battery" is slightly smaller; in addition, compared to lithium-ion batteries will be cheaper, mostly used in hybrid cars.
3. Maintenance-free lead-acid batteries. Performance will be worse; price will be cheaper, this type of battery is very common in the retail market.
4. Lead-acid batteries that require maintenance. The performance of the four types of batteries is the worst, and the price is also the cheapest, which is basically on the verge of being obsoleted.
