ECH-2590 Dual Bay Smart Charger for BB-2590/U Li-ion Battery

The ECH-2590 dual bay smart charger is equipped with independent LED indicators for each charging bay, providing real-time charging status at a glance:

Note: Each of the two charging bays has an independent LED indicator. Both bays can charge simultaneously with independent status monitoring.

The ECH-2590 integrates a comprehensive multi-layer intelligent protection system to ensure safe and reliable charging for BB-2590/U Li-ion batteries:

• ⚠ Temperature Protection — Real-time temperature monitoring with auto-shutdown when abnormal heat is detected, preventing thermal runaway

• ⚠ Defective Battery Identification — Automatically detects and rejects damaged or non-rechargeable batteries to avoid safety hazards

• ⚠ Low Voltage Detection — Pre-charge mode activates for deeply discharged batteries with low current to safely recover cell voltage

• ⚠ Overvoltage Detection — Constant voltage (CV) phase monitors cell voltage precisely and terminates charging at the optimal cutoff point

• ⚠ Full Charge Detection — Smart current taper detection automatically stops charging when the battery reaches full capacity

• ⚠ Max Charging Time Limit — Safety timer automatically cuts off charging after the maximum duration to prevent overcharge

• ⚠ 0V Battery Reminder — Alerts the user when a completely depleted (0V) battery is inserted, indicating the battery may need replacement

✅ Dual Independent Charging Slots
Two-bay design supports simultaneous charging of two BB-2590/U lithium batteries, greatly improving charging efficiency for field equipment deployment.

✅ Full Set Intelligent Safety Protection
Integrated multi-layer monitoring and protection circuit to avoid abnormal charging risks and extend battery service life effectively.

✅ Rigorous Factory Quality Control
Every charger passes complete aging testing before assembly to guarantee stable long-term continuous operation.

• ⭐ Multiple Built-in Protection Functions: Temperature Protection, Defective Battery Identification, Low Voltage Detection, Overvoltage Detection, Full Charge Detection, Max Charging Time Limit, 0V Battery Reminder, etc.

• ⭐ Premium Internal Configuration — Adopts high-grade electronic components and rigid hard PCB board for stable circuit output

• ⭐ Global Wide Voltage Compatibility — 110-240V wide AC input with replaceable UK, US and European plugs for worldwide application

• ⭐ Smart Charging Logic — Automatically judges battery status, adjusts charging current and stops charging once fully charged to prevent overcharging damage

• ⚠ Do not disassemble or modify the charger housing — internal high voltage components may cause electric shock.

• ⚠ Only charge compatible BB-2590/U Li-ion batteries — do not charge Ni-MH, Ni-CD or other chemistry batteries with this charger.

• ⚠ Keep the charger away from water, moisture and direct sunlight — do not expose to high temperature above 60°C.

• ⚠ Do not use the charger in hazardous, flammable or explosive environments.

• ⚠ Always disconnect the power supply when the charger is not in use.

• ⚠ Stop charging immediately and contact support if abnormal heat, odor, swelling or leakage is detected.
