Yes, that is the cord. What is the widest part of this cord called, near the micro USB end? This cord looks identical to the one that came with my 436HP. There is an inward curve on the micro USB plug too.
SDS100/SDS200: Swollen Battery?

Yes, same cable.
Bingo! I figured out what happened. Last Friday, I was carrying four bags. I got tangled in some way and my derrière hit the concrete very hard. After I rewound my memory of this, I remember what happened. I had this battery in my back pocket. I asked a witness if I landed on the side where I had the battery and they confirmed this. I have never had these batteries overheat in my hand or charger. Yes, the radio gets warm, but not nut-toasting.
Knowing about the potential overheating problem, I am going to be careful. I am considering not running this radio in my hard leather case. I am also considering moving blankets away from this radio when I monitor at night. Generally speaking, I will listen until I drop off. When my BT headphones come, I can leave the radio on the side of the bed instead of the middle.
Thanks for the help.

I got brave and dropped the bent battery into the radio. No issues whatsoever. I believe there is enough clearance to accommodate the small bend in the metal. There is no evidence of overheating from what I can observe.
As a guess, verify the voltage going into the battery. Then the amperage. The choke thingy has nothing to do with voltage or amperage in amount of, while charging. Swelling of the battery may suggest overcharging. Charging too long? Could be there is a governed duration of actual charging by way of a limiting circuit that may use a voltage or amperage limit to stop charging or even the temperature of the battery itself that is not working. Make sure the connection is clean etc. for resistance. Swelling of a LiPO suggests overcharging and a overheat condition. It may stay in charging mode and fail to stop until damage has occurred and then swelling is found. With the cost of the Radio, I wouldn’t let it change long on its own.
A majority of the complaints seem to be those that use the external chargers. I've been charging in the scanner for over 3 years and none of those issues are present.
I was not aware of how the charging was performed on this model, whether exterior or in case.
if exterior, it maybe the charging circuit tops it off too much.
(40 years!. My first was a Heathkit)
It does allow for internal charging, but many are reluctant to do so for various reasons.
Thank you. There is no evidence of a distorted battery, black material. But, the metal on the back came from my arse hitting the ground with the battery inside. But, I will take heed of your advice. Thank you.
I shy away from internal charging from my GRE PSR 500 days. I hate jacking around with the ports as well. I have had loosened USB connections on both of my 436HP units. If I want to do GPS, I will go internal. I never use that blasted GPS connection. It is just the way I roll.
I never every charged my 436HP. I bought Eneloops with a Lacrosse charger (great one). It is now gathering dust. LOL.
I also have an SDS100 and yesterday discovered a swollen battery. I have been charging it in the radio (no external charger). I decided to stop after hearing it was unwise to charge in the radio. Since I prefer AC or DC power I decided to sideline the battery until I could get an external charger. Yesterday I went to check the power level in it and discovered the battery door would not close. Upon further inspection I noticed the entire top of the battery has swollen (metal side expanded outward). By top I mean the top as it sits in the radio. I have not dropped it or exposed it to the weather.
So now along with a broken battery door clip I have no battery. I picked up the radio a couple of months ago from a stand and the battery clip was laying under the radio. No one else has access to the radio.

Damn, that is a rough patch you hit. I would be absolutely livid. There is a fellow on RR who does internal GPS. He sells a more formidable battery door. However, he has been absent as of late. I believe he is a bit behind.
Since I knew I could not go to Walmart to buy batteries for this radio, I bought 4 batteries. One of them is the original battery. I use this one, with the smaller battery door, for my MAXX mount on longer trips.
Reportedly, the innards of this radio require a lot of power. This is the down side of this radio. Best of luck to you. I hope things work out for you. God bless.
FYI see my thread in Uniden Prospective Owners for the current best pricing on the Uniden EBC100 External Battery Charger for the SDS100: SDS100: - Current Pricing Options for Uniden EBC100 External Battery Charger for SDS100
Following are the Uniden EBC100 External Battery Charger Specifications which were obtained from the Walcott Radio website (https://www.walcottradio.com/uniden-ebc100-external-battery-and-charger-p-3269.html). It also states on that same website "Battery clicks in place in the charger and a red LED light lets you know it's charging. When it's fully charged the light turns green to let you know it's ready to go. Charge time is approx 6.5 hours for a fully depleted extended battery."
Uniden EBC100 Specifications
Precharge (<3.07V) | 145 mA |
Quick Charge (3.07V - 4.2V) | 1010 mA |
Top-off Charge | 4.2V until charge current drops to 100 mA |
High Temp Cutoff | 113 degrees F |
Low Temp Cutoff | 32 degrees F |
On Uniden SDS100/SDS200 Facebook group, another member who is using the external charger has reported the same issue. Could the charger (or a certain lot of them) continue to charge beyond the 4.2 volt maximum and overheat the battery?
I have "possessed" three external chargers and only one of them has worked right.
The first one would latch, but the pilot light would go out.
The second one was returned to Scanner Master last week. If you put the battery in the charger, it would not latch, at all.
I asked Scanner Master to inspect the charger.
If I possessed the means and knowledge, I would take the electronic guts out of this and remake it with a 3D printer.
God, I miss Regency.

Regency had it's problems too.
I had an HX1200 that I fried the battery when I used the wrong charger. Regency had no charge protection in the radio only on the charger.
The other thing was the plastic tray the battery sat on in the radio had a metallic coating that could cause a short.
Back to the original problem, I will use the charger that comes with the radio if I am listening and need to power it. If I am only charging and not listening I use a charger with a lower amp output. This will take longer but the battery stays cooler.
I believe my HX-1500 used AA batteries and I never ever charged them in the radio. I also owned a MX-7000, but the keypad stopped working.
So, you are talking about a charger that goes into the port, not an external?
Correct, I used the port on the bottom of the radio. I later bought the drop in charger for it.
I used a 12v charger that had a 1 amp rating and the battery didn't explode per-say but it did leak acid all over the inside of the radio.
Regency used a 9v charger with like a 500ma rating. Cost me some serious $$$'s to repair.
I should also mention that the polarity was reversed, negative tip and positive barrel.
Now, I am getting confused.
I am back on the SDS 100 external battery charger. So, you use a lower level charger for the charging port on the SDS 100 right?
Or, are you talking about a lower-powered charging cord that will fit into the SDS 100 battery charger, with the same polarity?
