LiFePO4 Replacement Batteries for SLA Batteries

The following LiFePO4 batteries can be used for direct replacments of SLA batteries.  These batteries are superior compared to lead acid batteries because of their (1) high specific energy capacity, (2) long cycle life [~2000 cycles], (3) compact size, (4) light weight, (5) superior thermal and chemical stability, (6) enhanced safety, (7) improved cost performance, and (8) enhanced charge and discharge rates.  (Please note that the batteries should be charged with a compatible LiFePO4 charger.  It is very important to use a LiFePO4 charger for charging LiFePO4 batteries, and not a lead acid charger.)  You can contact us if you have any questions.
