7.7V Li-Polymer Smart Battery for Hytera PDC680 / PTC680 / PDC690 PoC Radios
The BP2402 (2400mAh) and BP4005 (4000mAh) are 7.7V lithium-polymer smart replacement batteries engineered for Hytera PDC680, PTC680, PDC690, and PDC690S Push-to-Talk over Cellular (PoC) radios. Hytera — the world's second-largest professional mobile radio manufacturer — equips its PDC/PTC smart radio series with intelligent battery technology that communicates charge cycles, remaining capacity, and authentication data directly to the handset. These replacement cells maintain full smart-battery functionality at a fraction of OEM cost.
Available in two capacity tiers: the BP2402 (2400mAh) for standard daily shifts, and the BP4005 (4000mAh) for extended operations — security patrols, event management, and field service teams that demand all-day runtime without swapping batteries.
Key Features
- Smart Battery Technology: Retains full communication with the host radio — displays real-time charge percentage, cycle count, and battery health status on the PDC/PTC screen, exactly like the OEM cell.
- Two Capacity Options: BP2402 (2400mAh, ~18.5Wh) for standard shifts; BP4005 (4000mAh, ~30.8Wh) delivers 67% more runtime for demand-critical deployments.
- Li-Polymer Chemistry: Higher energy density than standard Li-ion — thinner, lighter, and less prone to swelling under repeated charge cycles.
- Fast Charge Support: Compatible with Hytera rapid charger systems — charges from 0 to 80% significantly faster than nickel-based alternatives.
- Multi-Layer Protection: Integrated PCB safeguards against overcharge, over-discharge, short circuit, and thermal runaway.
- CE / RoHS / FCC Certified: Meets international safety and EMC standards for professional radio equipment.
- 1-Year Warranty: Full replacement coverage against manufacturing defects.

About the Hytera PDC / PTC Smart Radio Series
Hytera Communications (Hytera, SZSE: 002583) is the world's second-largest professional mobile radio (PMR) manufacturer after Motorola Solutions, headquartered in Shenzhen, China. The PDC680, PTC680, and PDC690 are PoC (Push-to-Talk over Cellular) smart radios — combining the instant group communication of traditional two-way radios with 4G/LTE cellular connectivity, Android OS, and a touchscreen interface.
These radios are deployed globally across public safety (police, fire), security teams, event management, logistics, and industrial facilities. Unlike a basic walkie-talkie accessory, the Hytera smart battery actively communicates with the handset's operating system — a third-party battery that fails to authenticate or report capacity correctly will trigger persistent warnings and may limit functionality. Our BP2402 and BP4005 are engineered to maintain full smart communication, ensuring seamless integration with existing radio fleets.
BP2402 vs BP4005 — Which One Do You Need?
- BP2402 (2400mAh): Ideal for standard 8-hour shifts with moderate talk time. Lighter weight, lower cost — best for teams with access to charging between shifts.
- BP4005 (4000mAh): Designed for extended operations — 12+ hour shifts, multi-day events, security patrols, or field teams without reliable charging access. 67% more capacity translates to significantly fewer battery swaps.
Frequently Asked Questions
- Q: Will my radio recognize this as a genuine battery?
A: Yes. Our replacement maintains full smart-battery communication — the radio displays remaining capacity, charge cycles, and battery health exactly as it would with the OEM cell. No warning messages, no limited functionality. - Q: What's the difference between BP2402 and BP4005?
A: Both are 7.7V Li-Polymer. BP2402 = 2400mAh (~18.5Wh) for standard shifts. BP4005 = 4000mAh (~30.8Wh) for 67% more runtime. The physical size is identical — both fit the same radio models. - Q: Does this battery work with the Hytera rapid charger?
A: Yes. It is fully compatible with Hytera desktop chargers and rapid charging systems. No special charger required. - Q: How many charge cycles can I expect?
A: Rated for 500+ full charge/discharge cycles under normal use, translating to 2-3 years of daily service. - Q: Is there a warranty?
A: 12-month replacement warranty. If the battery fails under normal use, we replace it promptly.
Installation & Maintenance
- Installation: Power off the radio. Slide the old battery downward to release. Align the new battery with the radio body and slide upward until the latch clicks securely.
- First Use: Charge to 100% before first deployment. The radio's screen will display charging progress in real time via smart battery communication.
- Storage: When not in use for extended periods, store at 40-60% charge in a cool (15-25°C) environment. Avoid storing at 0% or 100% charge for weeks at a time — this extends Li-Polymer lifespan.
- Routine Test: Check battery health via the radio's built-in battery status screen every 3 months. Replace if cycle count exceeds 500 or runtime drops noticeably.
- Cleaning: Wipe exterior with a dry or slightly damp cloth. Do not use solvents or submerge.
- Disposal: Li-Polymer batteries require specialized recycling. Return to an approved e-waste facility.
