Lithium Ion batteries are charged with an absorption voltage of 14.25 V for 12 V, and 28.5 V for 24 V systems. The float voltage is 13.5 V for 12 V and 27 V for 24 V systems. A rule of thumb for gel and AGM batteries states that the minimum charging current should be 15 to 25 % of the battery capacity.
Some batteries however need a higher absorption voltage to fully charge them (tubular or thick plate deep cycle batteries for ex.), and open, flooded, batteries in general can be charged faster by not only increasing the bulk charge rate, but also the absorption voltage.
For wet lead-acid batteries, the absorption voltage is 14.25 V for 12 V systems and 28.5 V for 24 V systems. The float voltage for this type of battery is 13.25 V for 12 V and 26.5 V for 24 V systems. All of these figures are for 25 °C. Lithium Ion batteries are charged with an absorption voltage of 14.25 V for 12 V, and 28.5 V for 24 V systems.
Often the absorption charge voltage of a battery does not exceed the gassing voltage limit (approximately 14,4 V for a fully charged 12 V battery).
No temperature compensation. Absorption time is approximately 20 minutes per battery, if possible. For a 12V system, we really want to emphasize reaching 14.2V – 14.6V for bulk and absorption and float to be 13.6V or lower. For a 24V system, we suggest a bulk and absorption rate of 28.4V– 29.2V and float to 27.2V or lower.
Some charging profiles offer a storage mode. This is not needed for a lithium battery, but if the charger has a storage mode then set this to the same value as the float voltage. Some chargers have a bulk voltage setting. If this is the case, set the bulk voltage to the same value as the absorption voltage.
As batteries are charged they go through 3 different states - bulk absorption and float. Here''s what is happening at each of these stages and a quick overview of the changing behaviour of the …
During absorption, the charger applies a constant voltage, called the "absorption voltage." As the battery''s open-circuit voltage approaches the absorption voltage, the current flow steadily decreases down to zero.
Bulk, charge at charger/ battery max current until voltage rises to the absorption Voltage. At this point the battery is somewhere around 80-90% charged. Absorption, keep …
