USB Charger for Compatible LIR Coin Cells

Recharge compatible lithium-ion coin cells from a suitable USB supply. This compact charger is for users matching LIR cell chemistry, voltage and size before charging.

• ✅ Reuse compatible rechargeable cells — The charger is stated for selected LIR formats.
• ✅ Power from USB — The stated input is DC 5 V.
• ✅ Keep charging items together — A USB cable is included.
• ✅ Check the output position — Two stated current levels apply to the port groups.

Match the Rechargeable Cell Before Charging

Confirm the exact cell chemistry and charging voltage before placing a battery in a slot. Similar coin-cell dimensions do not mean the batteries can share a charger.

Do not charge disposable cells. ML2032 compatibility is not established by the consistent LIR specification, and unverified protection functions are not a substitute for correct battery matching.
