The ultra long service life design of lithium storage battery eliminates the need for maintenance in use, greatly reduces the management cost and improves the management efficiency.
The lithium storage battery can work compatible with existing equipment (including lead-acid battery) and also supports battery floating charge mode. It is the best solution to replace the lead-acid battery without additional change or replacement of other equipment, so as to reduce the trouble of equipment upgrading for customers.
The design life is at least 10 years, and the actual total cost of ownership (TCO) is much lower than that of traditional lead-acid batteries.
