About this replacement
Hytera PD980 / PD985 Series — 7.4V Li-ion Replacement Battery (BL2016 / BL3004)
This is a 7.4V, 3350mAh lithium-ion replacement battery for the Hytera PD980, PD985, and PD985B portable two-way radios. It matches the OEM voltage rail and connector pinout for these professional land mobile radios. Capacity figures come from the product data — 3350mAh / 24.79Wh.
- PD980 / PD985 platform fit: Both the PD980 and PD985 series run the same 7.4V battery architecture, share the same multi-pin connector, and use the same BMS handshake sequence with Hytera chargers. That is why a single battery covers both radio lines — the pack, the contact layout, and the charge acceptance protocol are identical across the group.
- Bench tested on actual hardware: We cycled this pack through full charge and discharge on a PD980 body, monitoring BMS cutoff voltage and transmit-load response. The cell stack held voltage under sustained PTT draw without triggering overcurrent protection, and the charger accepted the BMS handshake correctly on first insertion.
- First-insertion contact check: If the charger dock shows a fault LED on first seating, remove the battery and wipe the gold contact strip with a dry cloth before reinserting. The Hytera charging platform requires a clean contact cycle to complete the BMS handshake — contamination on the contacts is the most common reason a new pack is rejected at the dock before charging begins.
Why the PD980 drops to reduced TX power mid-shift on a new battery
The PD980 monitors battery voltage continuously during transmission. When voltage sags below the radio's internal threshold under sustained RF output, the firmware steps down transmit power to protect the final amplifier stage. A new cell at storage voltage — typically around 3.7V per cell — has less headroom than a fully charged pack at 4.2V per cell, so this behaviour can appear on the first shift before the battery has completed a full charge cycle. Run the pack through one complete charge before putting it into a heavy-use rotation. After a full charge, the 7.4V nominal pack should hold well above the sag threshold under normal PTT duty cycles.
Bar indicator showing fewer bars than expected after installing a new BL2016
Hytera portables use a voltage-threshold system to drive the bar indicator — each bar corresponds to a voltage band, not a calculated capacity percentage. A new pack shipped at storage voltage reads lower on that scale, so the display may show one or two bars fewer than a fully charged original. This is not a fault with the cell. Charge the battery fully in the Hytera dock until the charger shows a solid green, then insert it into the radio — the bar indicator will reflect the correct charge level once the pack reaches its top-of-charge voltage of approximately 8.4V.
