Hey all, with the Battery hub that holds fill for radios what batteries do what in it? It holds I think a set of AA and a BA5372. Do you need both sets to make it work or just the BA5372 to hold fill? I've been tiring to find info in the TMs I have but coming up short. Also if only the BA5372 is needed what are the AA for?

Thanks for everyone's help just trying to get ready for BA in the next few months. Be sure to see my other posts; no, I don't have an S6 shop in my unit to ask. Unfortunately am it, and USAR.

Per https://www.prc68.com/I/BA5590.shtml , "...holds qty 4 AA batteries and 1 CR-123A lithium battery. This is meant to be a hold-up battery for when the radio is used in a vehicle setting."

SPC(P) Matthew H. The Hub battery holds the fill (BA537X last number denotes generation of battery).
The battery pack powers the radio when disconnected from vehicle power.
You should need both to hold the fill if the radio is removed, but we always wanted the pack installed in case we had to pull the radio for dismount.
My recommendation is get your hands on the rechargeable batteries and a charger bank. There are different versions, but the best BB-2590/U is rated at 7.5 Ah instead of 6.8 Ah for the old version. The new nomenclature is is BT-70791C I think, but its been a while since I had to mess with batteries.

SGT (Join to see) is correct that you can get the one that holds a mess of AA. They are convent, but run through the batteries like crazy and carrying extra really isn't an option for some units. I am sure supply hates having to order bulk AAs that sit and gather dust and you have to drag a tri-con around just to have enough extra AAs for NVDs.

Thanks CSM for the Info. Your talking about the lithium-ion rechargeable battery's to
field a manpack right? I was always told not to use those in the vehicle mounts due to potential of fire or catastrophic failure, and only to use Hubs to holding fill is that true? The unit just order me the hubs, I just tiring to get what sets of batteries I need to hold on hand. I am going to have supply order some BB-2590/U, the ones we have are from 2008 and I only have 3 that work. I figured I have a few of these on hand for redundancy and if we need to set up a manpack.

Thanks for all your input it helps me out a lot to get the unit rolling forward.

SPC(P) Matthew H. - We used them all the time. We had a shortage of the disposable and a ton of the rechargeable (mine detectors with GPR take the rechargeable). Never had a fire. Not that should contradict any PM bulletins, but I would do some research on that claim.

As far as the maniac, it depends on what series of radio you are using. If you have the "ASIPS" (the one that does not need a separate battery compartment), we just left the battery in it.

I have had a few commo NCOs, and typically they have some sort of shorthand for figuring out how many "good" batteries they needed. I think it was something like 4 per radio on the property book. 2 for the hand receipt holder and 2 for stores. They also had bank chargers one for each platoon and one for the commo shop. But they also had three chargers because we also had MBITERs and Harris radios.

Typically, the BA5372 serves as the primary power source for radio fill operations. It's designed to provide reliable power to ensure smooth communication. As for the AA batteries, they might function as backup power or supplementary energy sources, offering an additional layer of reliability in case of emergencies or extended operations.
By the way, if you're looking for reliable battery options, you might find this link helpful: https://www.pkcellpower.com/limno2-battery/ . They offer quality batteries that could be useful for your equipment needs.
