Rechargeable Batteries

High-performance rechargeable batteries are the backbone of modern electronics. Whether you need 12V SLA batteries for a UPS system, high-drain 18650 Li-ion cells for DIY projects, or standard Ni-MH AA/AAA replacements, we have the right power solution. Backed by 20 years of retail experience in Sham Shui Po, our technical team provides on-site battery voltage testing and engineering-grade advice to ensure you get the safest, most reliable cells for your specific devices.

A Comprehensive Range of Battery Chemistries

We stock a diverse selection of battery types to suit specific voltage requirements and device compatibilities:

  • Lithium-ion (Li-ion) Batteries: Featuring popular sizes like 18650, 21700, and 26650. Important Note: Unprotected bare cells are designed for custom battery packs and devices with a built-in Battery Management System (BMS). They are not suitable for standard consumer flashlights without low-voltage protection.
  • Sealed Lead Acid (SLA) Batteries: Ranging from 12V 1.3AH to 18AH. These maintenance-free batteries are the industry standard for UPS (Uninterruptible Power Supply) systems, CCTV monitoring backups, and emergency lighting.
  • Nickel-Metal Hydride (Ni-MH): Available in standard AA, AAA, and 9V sizes. Ideal for replacing disposable alkaline batteries in game controllers, toys, and wireless mice to reduce environmental waste.

Frequently Asked Questions (FAQ)

Q: Can I use any 18650 battery for my high-power flashlight?

A: No. High-drain devices require batteries with a high continuous discharge current (e.g., 10A or higher). Additionally, you must check if your device requires a "button-top" or "flat-top" cell. Feel free to bring your flashlight to our physical store, and we will test and match the exact fit for you.

Q: How often should I replace the 12V SLA battery in my UPS?

A: Typically, SLA batteries in UPS systems last 3 to 5 years, depending on usage frequency and ambient temperature. If your UPS alarms frequently or fails to hold a charge during a power dip, it's time for a replacement. We stock fresh SLA batteries ready for immediate in-store pickup.
