Hi. Is there a battery pack for this radio that would allow me to insert regular AA batteries?

SDS100/SDS200: SDS-100E battery pack?

Nope, you can use a 5-volt power pack with a USB cable for power though.

No. To be able to run the scanner if the batteries go low you can use an external battery bank connected to the micro USB port. One that equals the original batteries 5AH are very small and allows 6-7 hours of run time and costs much less than a Uniden battery.

No there is not. Uniden has a history of making many of their scanners requiring a proprietary overpriced battery packs. Remember the BC100XLT and BC200XLT, etc? What's worse if the battery pack goes dead you have to wait for it to charge or carry around spare packs.
The current draw on the the SDS100 is substantial and it wouldn't run very long on 'AA's so it wouldn't be practical. If they had designed their battery pack to be the full length of the radio like some two-ways it would be thinner and easier to keep a spare in a pocket.

Oh, good. That will do just fine. What battery pack would you recommend?
Do you mean a powerbank?
Any USB Battery Powerbank/powerpack should do, pick something that has a good capacity and weight according to your needs.
I use one that is rated 30,000 mil or 30 amps over 5 times the original battery

About to try doing this to power the Uniden GPS accessory with a phone charger battery as soon as the USB-DC plug cable arrives from Amazon.

That's probably the proper name for it. Choose the smallest one that can run the scanner for the number of hours you need. Scanner takes something like 850mAH and if you can run 6 hour on its own battery you probably don't need another 6 hours, making it 12 hours. So a 5AH are probably more than enough. If you transport yourself by car then you can always charge while listening.

You need to be careful.
There's many cheap USB powerbanks on Amazon that claim to be 30,000 mAh and above.
If you check the reviews, occasionally someone has gone to the trouble of checking the capacity of these cheap powerbanks, and they're nowhere near 30,000 mAh, i.e. closer to 10,000 mAh = the cost of an accurately rated 10,000 mAh USB powerbank.
Mine is an anker if I remember correctly

I believe Anker is one of the reputable brands.
It's the unknown brand names that seem to appear out of nowhere where caveat emptor applies.
Like the cheap Chinese NiMH AA rechargeables that claim to be 2,800 mAh (EBL) and higher.
I can guarantee they're not 2,800 maH.
The highest rating the technology is capable of is 2,700 mAh, i.e. the Japanese-manufactured Powerex AAs, they're accurately rated and expensive.
I once bought a set of four AAs by an obscure brand name that claimed to be 3,000 mAh for $6.00 just to check their rating.
Checked their capacity in my Maha charger using the discharge function and in reality they were 2,000 mAh.

Yes Anker for certain!
A rough and ready check to determine whether a 30,000 mAh power bank calls under the category of "too good to be true at this price" is to check its weight in the specifications listing.
Unless it's very substantially higher than the weight of the average 10,000 mAh powerbank = "too good to be true".
Most of the newer high capacity powerbanks are using a size 21700 5000mahr (3.7v nominal 4.2v peak LIION) battery's...
They are usually connected in parallel to obtain the ampacity rating of the powerbank... A boost converter is then used to get your 5v USB power...
So depending on the percent efficiancy of the boost converter... No matter what it is... You will never see the total capacity of the powerbank's
rating available for you to use... Due to loss in the boost converter...
Even though the Samsung shown below says 5000... It could have a 5000mahr capacity, but more than likely it is a bit lower than that...

Regarding mAh delivered, it's always going to be substantially lower than the stated value for the reasons you give, possibly only 70% of the rated value given in the spec. details.
Even so, you see these cheap powerbanks on Amazon rated at 30,000 mAh and a whole bunch of 5-star reviews exclaiming what a great deal this is, great value etc.
And interspersed with the above, some tech-savvy reviewers who know the technology, how it all works etc. giving a 1-star review because they've determined the actual capacity and it's nowhere near the quoted capacity even taking into consideration the inevitable lower mAh delivered due to efficiency losses.
I learned this early on.
A while back I bought one of these solar-capable powerbanks rated at 20,000 mAh, you can still see them on Amazon all over the place
This thing was at maximum 5,000 mAh and you can forget ever charging it via the sun. I had this thing in direct sunlight for days and the most it ever achieved was "one green" light out of 4 on the charging state indicator.
Lots of folks gave it a 5-star review too!
Live and learn...

I agree with you on the cheap powerbanks... Most of those use gargage batterys...
Making claims that are not true...
I bought this one a couple of years ago from Amazon... But they got smart and don't sell on Amazon anymore...
Notice the price... And the coupon code... I paid $15 for it... And it uses 3 of those Samsung batts... Still going strong too...
