CT-ENERGY 4-Bay Lithium Coin Battery Charger for LIR Cells — USB-C, Dual-Speed Charging & Child-Safe Case

If you use button batteries in remotes, fitness trackers, key fobs, sensors or small electronics, this compact CT-ENERGY charger streamlines recharging. It holds four LIR coin batteries at once, supports several popular sizes, and connects by USB-C for modern convenience. The unit includes safety features and a child-proof storage case to keep spare cells secure.

What battery sizes does this charger support and how long does charging take?

The charger is compatible with multiple rechargeable LIR coin cell sizes commonly sold for consumer electronics. Charging duration depends on battery capacity and the selected port's current (20mA or 40mA).

• Supports LIR2450, LIR2430, LIR2032, LIR2025, LIR2016, LIR1632, LIR1620 (and similar LIR types).
• LIR1632/1620 typically finish in about 1 hour.
• LIR2032/2025/2016 generally complete within roughly 2 hours.
• LIR2450/2430 usually require around 3 hours with the appropriate port.

How do I know when batteries are charged and can it charge different sizes at once?

Dual-color LED indicators give an immediate visual status for each slot so you can tell charging progress at a glance. The charger accepts mixed sizes simultaneously, allowing you to recharge several different LIR cells without swapping devices.

• Red LED = actively charging; blue LED = finished or empty slot.
• Four independent bays: charge up to four coin cells at the same time.
• Two output modes—20mA for standard charging, 40mA for faster charging on compatible larger cells.

What safety features protect my batteries and devices?

CT-ENERGY built the charger with multiple safeguards to reduce risk while topping up small lithium cells. Protective circuitry helps prevent typical hazards associated with battery charging when used correctly.

• Overcharge protection to avoid stressing batteries after full charge.
• Short-circuit protection to stop current flow if a fault occurs.
• Designed specifically for rechargeable LIR coin batteries—not for disposable non-rechargeable cells.

What comes in the box and how do I store spare batteries safely?

Along with the charger, the package includes practical accessories for immediate use and secure storage of spare cells. A child-proof case helps minimize accidental access to loose button batteries.

• 1 × CT-ENERGY 4-bay coin battery charger and 1 × USB-C charging cable for power.
• 1 × user manual to guide correct operation and safety notes.
• 1 × child-proof battery case with screws and small screwdriver for secure storage.

Who is this for: This CT-ENERGY charger is ideal for hobbyists, families, and small-business owners who regularly use rechargeable coin cells in everyday gadgets. If you want faster turnaround for multiple button batteries, clear charging feedback, and added storage safety, this compact USB-C charger provides a practical, organized solution without complicated setup.
