Smartoools Type-C AAA Lithium Rechargeable Battery (4Pcs Pack)

The Smartoools Type-C AAA Lithium Rechargeable Battery (4Pcs Pack) brings modern USB-C convenience to everyday AAA-powered devices. Instead of throwing away old alkaline batteries or hunting for a dedicated battery charger, simply plug a standard Type-C cable directly into the battery itself and recharge it like a phone. Each cell maintains a steady 1.5V output throughout its discharge curve, ensuring consistent performance in remotes, wireless keyboards and mice, clocks, toys, flashlights, and other low-to-medium drain electronics. Built-in protection circuitry guards against overcharging, over-discharging, and short circuits, while the pack is rated for up to 1200 recharge cycles, making it a genuinely eco-friendly and cost-effective alternative to single-use batteries.

Frequently Asked Questions

Q1: How do I charge these AAA batteries?
A: Each battery has a small USB Type-C port built into the top. Plug in any standard Type-C cable (one is included) connected to a USB power source to charge.

Q2: How long does a full charge take?
A: A full charge from empty takes approximately 2 hours, though this can vary slightly depending on the charger/power source used.

Q3: Can I use these in any device that takes AAA batteries?
A: Yes. They output a regulated 1.5V, the same as standard alkaline AAA batteries, so they work in remotes, clocks, toys, flashlights, wireless mice/keyboards, and similar low-to-medium drain devices.

Q4: Are they safe to leave charging overnight?
A: Yes. Built-in protection circuitry prevents overcharging, over-discharging, and short circuits, so they can be safely charged unattended.

Q5: How many times can I recharge each battery?
A: Each cell is rated for up to approximately 1200 recharge cycles before capacity noticeably declines, which is far more than typical NiMH rechargeables.

Q6: Does the pack include a charging cable?
A: Yes, a USB Type-C charging cable is included in the box along with the 4 batteries.

Q7: How do I know when a battery is fully charged?
A: Each battery has a built-in LED indicator that shows charging status and changes or turns off once fully charged.

Q8: Are these batteries suitable for high-drain devices like cameras or flash units?
A: These are best suited for low-to-medium drain devices such as remotes, clocks, and wireless peripherals. For high-drain devices, performance may vary compared to dedicated high-discharge rechargeables.

Q9: What is the warranty on this product?
A: This product comes with a 7-day replacement warranty when purchased from T-TECH, along with cash on delivery across Bangladesh.

Q10: Can I mix these with regular alkaline AAA batteries in the same device?
A: It is not recommended to mix battery types or charge states in the same device, as this can lead to uneven power delivery. Use a full set of these batteries together for best results.
