LiFePO4 batteries don''t need to be float charged because they don''t leak charge the way lead acid batteries do. If you can, disable float charging on your charge controller or battery charger. If you can''t, prevent the battery from entering float charge by setting the float voltage to that recommended in the battery manual — usually 13.6 volts ± 0.2 volts.

6 FAQs about [Lead-acid battery characteristic curve]
What is the coulombic efficiency of a lead acid battery?
Lead acid batteries typically have coulombic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
What is the difference between a deep cycle battery and a lead acid battery?
Wide differences in cycle performance may be experienced with two types of deep cycle batteries and therefore the cycle life and DOD of various deep-cycle batteries should be compared. A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid.
What is a good coloumbic efficiency for a lead acid battery?
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
What is a lead acid battery?
The correction involves the efficiency value of each process: = efficiency for charge state and = for discharge state. A lead acid battery is defined as empty if battery terminal voltage reaches below 10.5V. At this condition, the battery can no longer be used and it is recommended to be recharged as soon as possible.
What are the advantages of lead acid batteries?
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
What are the problems encountered in lead acid batteries?
Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.
