12.6V 2A Lithium Battery Charger for Power Tools – DC 5.5mm
12.6V 2A Lithium Battery Charger for Power Tools
Keep your power tools running at peak performance with this professional-grade 12.6V 2A Lithium Battery Charger. Designed for 3-cell lithium battery packs, this compact and reliable charger features smart two-stage charging technology — constant current followed by constant voltage — to efficiently and safely top up your batteries every time.
Smart Charging Indicator Lights
Never guess your charge status again. The built-in LED indicator system keeps you informed at a glance:
- Green Light (No Load): Charger is ready and connected to power, no battery detected.
- Red Light: Charging in progress — initial constant-current stage underway.
- Green Light (Full): Battery is fully charged and ready to go.
Key Features
- Output: 12.6V DC / 2A (2000mA)
- Connector: DC 5.5 x 2.1mm barrel plug — widely compatible with most power tool battery packs
- Two-Stage Charging: Constant current charging → switches to constant voltage as battery nears full capacity, reducing current gradually for a safe, complete charge
- Short Circuit Protection: Built-in safety circuit prevents damage to your battery and charger
- Plug-and-Charge: Ready to use straight out of the box — no setup required
- Available in 4 color options to suit your workspace or personal style
- Compatible with voltage range: 40–1000V (40VA type)
Why Choose This Charger?
This charger uses an intelligent two-stage process that first charges at a steady 2A current, then seamlessly transitions to constant-voltage mode as the battery reaches capacity. The current gently tapers off, ensuring a full charge without overcharging — extending the life of your lithium battery pack. The result: a professional charging experience in a compact, affordable package.
Ideal For
- 3-cell (3S) lithium-ion and lithium polymer battery packs rated at 11.1V nominal / 12.6V full charge
- Cordless drills, screwdrivers, and handheld power tools
- DIY enthusiasts and professional tradespeople alike
- Workshop and jobsite use

Frequently Asked Questions
Q: What battery types is the 12.6V 2A Lithium Battery Charger compatible with?
A: This charger is designed for 3-cell (3S) lithium-ion battery packs with a nominal voltage of 11.1V and a full-charge voltage of 12.6V. It uses a standard DC 5.5 x 2.1mm barrel connector, making it widely compatible with many cordless power tool battery packs that use this connector type. Always verify your battery pack's voltage and connector type before use.
Q: How does the two-stage charging process work?
A: The charger begins with a constant-current stage, delivering a steady 2A (2000mA) to the battery. Once the battery voltage reaches 12.6V, it automatically switches to constant-voltage mode, during which the current gradually decreases until the battery is fully charged. The LED indicator turns green when charging is complete — protecting your battery and maximising its lifespan.
Q: Is this charger safe to leave unattended while charging?
A: This charger includes built-in short-circuit protection and an automatic cutoff when the battery reaches full charge. While these safety features provide solid protection, it is always best practice to charge batteries in a safe, ventilated area and avoid leaving any battery charger completely unattended for extended periods, as recommended by safety authorities.
Q: What does each LED indicator colour mean?
A: Green (no load) = charger is powered on but no battery is connected. Red = actively charging (constant-current stage). Green (with battery connected) = battery is fully charged. This intuitive light system lets you monitor charging progress at a glance.
