The ENL-BL2503 replacement battery is fully compatible with the following Hytera PD7 series DMR digital two-way radio models:

✅ Faithful OEM Replacement for Hytera PD700 / PD780 / PD70X / PD78X Series DMR Digital Radios
Direct replacement for Hytera OEM part BL2503, supporting PD700, PD780, PD70X, PD70XG, PD78X and PD78XG series professional DMR digital handheld transceivers. Plug-and-play fit, no modification required.

✅ 2500mAh High-Capacity Li-ion Cell Pack with 5-Protection BMS
Premium long-cycle Li-ion cells deliver stable 7.4V output and rated 2500mAh capacity — 25% more runtime than the standard 2000mAh BL2006 pack — for typical 12-14 hour extended shift operation. Built-in smart BMS module provides over current protection (OCP), over charge protection (OVP), over discharge protection (UVP), temperature sensor and reverse polarity protection — comprehensive safeguard against field failures.

✅ Compact High-Density Housing & Ultrasonic Welding Sealing
Robust ABS/PC composite housing with ultrasonic integrated welding sealing, golden plated brass low-resistance contacts — anti-drop, dustproof and moisture resistant. The 10.64*5.63*2.43cm high-density form factor packs maximum energy into minimal footprint while keeping the PD7 series radio balanced during extended carry.

• ⭐ OEM BL2503 Replacement — Faithfully matches original dimensions (10.64*5.63*2.43cm), drop-in fit for all PD700/780/70X/70XG/78X/78XG series DMR digital radios without chassis modification
• ⭐ 2500mAh High Capacity, 7.4V Stable Output — 25% more runtime than the standard BL2006, extended-shift DMR digital communication on a single charge, low self-discharge, no memory effect
• ⭐ 5-in-1 Smart BMS Protection — Over-charge, over-discharge, over-current, temperature and reverse-polarity protections are mandatory for Li-ion safety, keeping the pack safe during daily field abuse
• ⭐ Wide Temperature Tolerance — Performs reliably across -20 degrees C to 60 degrees C working range, ideal for outdoor and industrial environments
• ⭐ Industrial Craftsmanship & Warranty — Manufactured under strict aging test procedure, OEM private label and bulk customization available, 12-month full quality warranty

• ⚠ Do not disassemble, puncture, crush or modify the battery housing — internal cell damage may cause electrolyte leakage, overheating or fire. Stop using the battery immediately if you notice swelling, unusual heat, odor or deformation, and move it to a safe non-flammable area away from combustibles.

• ⚠ Keep battery terminals away from metal objects such as coins, keys and jewelry to prevent accidental short-circuit. Do not expose the battery to high temperature above 60 degrees C, direct sunlight or open flame for extended periods.

• ⚠ Only charge with a Li-ion compatible CC/CV (constant current / constant voltage) charger rated for 8.4V charging voltage. Do NOT use a Ni-CD / Ni-MH charger on this Li-ion battery — the cutoff logic is completely different and may cause overcharge, overheating or permanent damage.

• ⚠ Do not store the battery fully discharged for long periods. For long-term storage, keep the pack at approximately 40-60% charge in a cool dry place and recharge every 3 months. This Li-ion battery contains regulated lithium cells — do not dispose of it with household waste; return the spent battery to an authorized battery recycling collection point in compliance with local regulations.
