Will a Beta Kid charge Lead-Carbon (PbC) batteries?

[Free Energy Freak]

Just curious if Lead-Carbon (PbC) batteries would be included in "newer technologies"?

[ClassicCrazy]

 What does it take to charge a Lead-Carbon (PbC) battery that the Kid would not do ?

I looked up Lead-Carbon (PbC) battery charging setpoints but don't find any info - seems like Lead-Carbon (PbC) it is just a concept right now ?

I hope this helps


PbC batteries have unique properties that allow them to be fully charged in 5 hours when following the charge profile depicted in Figure 4-1. The minimum inrush current (initial current before the battery reaches its maximum charging voltage) should be 0.4C10, though higher currents are recommended if possible.  C10 is defined as the current required to fully discharge a PbC battery module in precisely ten hours. Once the voltage reaches the limit of 13.5 V for 12V models (18.0 for 16V models), the battery should be held at constant voltage for a duration of five hours to ensure full capacity return.

Upon receipt of new batteries, it is suggested that each battery be “conditioned” prior to formal measurement and testing.  Conditioning protocol is a simple discharge to 3.6 V for 12V models (4.8V for 16V models) at any discharge rate less than or equal to C/1. Then recharge by the standard method described above.

Charging a PbC Battery String

PbC battery series strings have a distinct advantage over leadâ€"acid battery series strings as they self-equalize to maintain low module-to-module variability. The recommended charge algorithm for PbC battery strings is a multiple-step constant current charge profile, which is outlined in Table 4-1 (ROW 1).   Each step lasts until one battery reaches 13.5 V for 12 volt modules (18V for 16 volt modules). As the steps are completed, the batteries at lower SoC will begin to catch up to the batteries at higher SoC in the string.  At this point, the batteries will be ready for use.  If the string is not to be used immediately, then the following periodic float charge algorithm shown in Table 4-1 (ROW 2) should be employed. This algorithm serves the same purpose as float charging in traditional VRLA string applications, and it is recommended when the string voltage drops below an average of the nominal voltage of the individual modules in the string (12V or 16V depending on module size).
