Uniden SDS100 Replacement Battery (BPS100)
About the SDS100 Battery
The Uniden SDS100 runs on a rechargeable Lithium-Ion battery pack that sits inside the back compartment of the scanner. The battery charges via USB while the scanner is in use or powered off, and the scanner can also be operated on AC power with the battery installed.
There are three reasons you'd want a spare BPS100:
- Extended field use: A second battery lets you swap in the field without needing to find a USB power source mid-session.
- Battery replacement over time: Lithium-Ion batteries degrade over charge cycles. After a few years of regular use, the original battery may not hold a full charge anymore.
- Emergency backup: For public safety monitoring during prolonged events or emergencies, having a charged spare on hand is practical insurance.

- Don't run fully dead regularly: Li-Ion batteries last longer when you don't completely drain them before charging. Try to charge before you hit 10–15% remaining.
- Avoid heat during charging: Don't leave the scanner charging in direct sunlight or a hot car. Heat degrades Li-Ion faster than anything else.
- Use the right charger: Always charge via the SDS100's USB port with a quality USB charger. Avoid no-name chargers that may not regulate voltage properly.
- Store at partial charge: If storing the scanner long-term, leave the battery at around 50–60% charge rather than fully charged or fully depleted.
- Replacement timeline: Li-Ion batteries typically deliver 80%+ of original capacity after 300–500 charge cycles. If you scan daily, plan for a replacement battery every 2–3 years.
Frequently Asked Questions
What battery does the Uniden SDS100 use?
The SDS100 uses a proprietary 3.7V Lithium-Ion battery pack. The official spare/replacement part number is the BPS100. Standard AA or AAA batteries are not compatible — the SDS100 only works with its proprietary Li-Ion pack.
Can I use third-party batteries in the SDS100?
Uniden only officially supports the BPS100 battery. Third-party batteries not designed specifically for the SDS100 may not fit correctly, may not charge properly, or may pose a safety risk. Stick with genuine Uniden batteries to protect your scanner and yourself.
How long does the SDS100 battery last on a charge?
Real-world battery life depends on backlight usage, signal activity, and whether the display is active. Typical usage runs 4–8 hours per charge. Reducing backlight brightness and using the scanner in lower-power situations extends runtime significantly.
Can the SDS100 run without a battery installed?
Yes. The SDS100 can be powered via USB without a battery installed, which is useful for home base use where you're always near power. The battery just gives you portable operation.
Is the SDS100 battery the same as the SDS150 battery?
No. The SDS150 uses its own proprietary battery. Batteries are not interchangeable between the SDS100 and SDS150. Always verify the part number matches your specific scanner model.
