My small battery is not swollen but it is not being recognized by my SDS100 and will not charge while in unit either. The battery indicator does not show any voltage. The red charge light blinks for about 10 seconds when hooked to power and then turns off. Will contact Uniden to see about a replacement battery.
SDS100/SDS200: **SAFETY ALERT** SDS100 battery severely swelled

Same here. I maintain about fifty LiPos in various sizes for my quads. Out of season with a four port balanced charger, figure most of an afternoon every couple of months just for maintenance, with some LiPos requiring an individual cell charge to bring back the cell before putting them on the balanced charger. Even so with top quality batteries I have had a few "puffers". Other than my tiny whoop, all batteries with a decent power density are charged outside with a five gallon bucket of sand on standby for fire suppression. When not in use the batteries are stored in steel ammo cans to contain a possible fire.
LiPos are used in RC suff due to leight weight, power density and cost. I'll add that I've spent much o my professional life advising electronics manufacturers heat on dissipation. IMHO LiPos do not belong in an EDC radio.
Even though the puffers in this thread are most likely due to user ignorance why wasn't proper storage addressed in the documentation?
When I purchased the SDD100 it was not clear that it relied on LiPos for power. As far as I am concerned this is the last straw, after Uniden's response during my last tech support call "This is the first I have heard of this. The last software update was supposed to fix this. You can wait for the next software update. If that doesn't fix it you can send the radio in for repair". I've had the TURD for a week, Uniden expects the customer to wait for a possible fix in the next software update and if that doesn't work send the radio in for repair (four to five weeks)? The folks running Uniden must be smoking the same stuff as all the Mil/Spec aerospace manufacturers I used to advise, whom insisted on spending our taxes on poorly engineered poopoo.
I hear a sad tune Whistling...

Easier said than done I'd think. They would probably need to design in safety circuits so AA batts cannot charge for example.

A safety measure to prevent the batteries from being charged I would not think at this point is an issue as it has been done on the 436 I think the issue was that too much power is required to operate the radio overall and Double A's couldn't do the job.
It would take 8 AA's @ 2500 mil to equal the large battery pack 4 in series and 4 in parallel to equal 4.8 volts @ 5000 mil

Glad I only have one battery that is inside the radio ...
LOL! I see what you did there.In the event the swelling persists longer than 4 hours, seek immediate medical assistance.
Unication LiPo batteries had similar problems, forcing the company to switch back to Li-ion last year. Realistically, rechargeable batteries should be relatively user-proof. You should not have to follow a "preflight checklist" before use that would challenge an electrical engineer.

And it would have to be as big as a group 27 battery. OK, maybe not quite that big.

Was there a specific reason that LiPo and not Li-ion batteries were used ?
Don't know for sure. I'd suspect Unication believed they'd provide better service under the challenging conditions their pagers are sometimes used. Or, perhaps the Li-Po just consumed less space than an equivalent Li-Ion. My G5 shipped with the Li-Ion and the battery cover extends out 1/8 inch beyond the body of the pager.
1/8th inch is normal for both types. Mine shipped with the Li-Po but still sticks out an 1/8th inch or so.
Other user reports of Unication replacing their defective Li-Po cells with an Li-Ion cell have never indicated a different battery cover was needed. I'd say the physical size must be the same between the two chemistries.
edit: My Li-Po cell is still fine in my G5.

It's a thread for any radios beginning with the letter "U".
And it's called "Uniden Tech Support" because.......?It's a thread for any radios beginning with the letter "U".
Some of you guys need to relax, he was speaking of similarities in batteries between unification (dare I say that word in this thread). Stop being so sensitive.
Back to topic, from what I understand the batteries are only having issues if out of the scanners at this point, correct?

Yes and Yes.
Because Uniden begins with a "U".
Uniden begins with You 'n I (UNI).
