I find it inexcusable that a lithium battery would swell this much in just over a years’ time.

I bought the scanner brand new, sealed from Bearcat Warehouse last year (8/23). The scanner has never, ever been exposed to extreme heat or extreme cold. It stays with me at home 95% of the time.

I noticed Thanksgiving 2024 that the battery was taking a long time to charge, I pulled it out and suspected it was starting to swell when I looked at the top part (silver color with the “Made in China”) sticker and could see slight rounding when looking edge on (it wasn’t flat like it used to be).

I ordered a new battery and the day it arrived, I installed it into my SDS100 and the charging time returned to normal. Incidentally, why does the scanner need to charge the battery after it’s been used on external USB power via the supplied power adapter and cable?

I left the battery out to sit in the same place to see what would happen, and within three weeks, the attached photo is the end result. Not good.

Normally, I run the scanner off USB external power using the power adapter and cable it came with from the factory, so I really don’t understand how the battery went bad in such a relatively short period of time.

I have the scanner set to charge only when the scanner is powered off/not charged while powered on via USB external power.

I know this issue has been brought up countless times before via other threads, but seriously, this much swelling in just over a year?

I’ve had lithium battery powered devices in various sorts and never saw a battery swell like this in such a relatively short period of time.

Could this be a serious quality control issue, or is it going to be dismissed as just yet another “fluke?”
