Philip Morris iQos Charger Compatible Battery 3.7V 2600mAh

Philip Morris iQos 2.4 Plus Charger Box — 3.7V Li-ion Replacement Battery (BAT.000046.RD)

This 3.7V, 2600mAh Li-ion cell replaces the internal battery in the Philip Morris iQos Charger and iQos 2.4 Plus Charger Box. The charger box stores charge to power your heating sticks between uses — when this cell degrades, the dock stops delivering consistent power to the holder. Part numbers BAT.000046.RD and 1UR18650Z-C007A both reference this cell.

• iQos Charger and 2.4 Plus Charger Box fit: Both the original iQos Charger and the 2.4 Plus Charger Box use the same 18650-format Li-ion cell on a 3.7V rail with the same connector and BMS handshake, so one cell covers both units.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on the iQos 2.4 Plus Charger Box. The BMS accepted the cell without fault flags and held the output rail steady through repeated holder-charge cycles.
• Post-session charging on the iQos dock: Do not place the charger box on its USB cable immediately after a long back-to-back session. Allow 15 minutes for the internal cell to cool below 40°C — charging into a warm Li-ion cell accelerates electrolyte breakdown and shortens cell life faster than normal cycle wear.

Why the iQos Charger Box stops delivering a full charge to the holder

The charger box acts as a portable power bank for the iQos holder. As the internal cell ages, its usable capacity drops — the box may still show a full indicator light but delivers less energy per transfer cycle. The holder then exits a heat cycle early because it received less charge than a full stick requires. Replacing the internal cell at this point restores the full transfer capacity the holder depends on.

Charger box LED flashing but holder not charging

A flashing LED with no charge transfer to the holder usually means the internal cell voltage has dropped below the BMS minimum output threshold — typically under 3.0V — and the BMS has blocked discharge to protect the cell. At this point, plugging the box into USB may not recover it if the cell has sat in deep discharge too long. Install a fresh cell, then connect the box to USB to let the new cell initialise. Confirm the holder begins its charge sequence within 30 seconds of being seated.
