Stop buying throwaway batteries! This 9V Double Charge battery is rechargeable — use it again and again instead of tossing single-use cells. It ships with a snap-on clip connector (red wire = positive, black wire = negative), so it connects to your circuit in seconds. Ideal 9V power for multimeters, smoke alarms, microphones, remote controls, toys and DIY projects — and for powering your Arduino boards on the go.

Key Features

• 9V rechargeable battery — recharge and reuse many times
• Double Charge design: longer life, more charge cycles
• Clip connector included — snap on, easy to connect and use
• 9V output, suitable for many electronic projects and devices
• Saves money versus single-use 9V batteries
• Compact, standard 9V form factor

How to Use (Usage)

1. Snap the clip connector onto the battery terminals (red = positive, black = negative).
2. Connect the red wire to your circuit’s positive input and the black wire to ground.
3. To power an Arduino: connect red to VIN and black to GND — 9V sits safely in Arduino’s 7–12V input range.
4. When the battery runs flat, recharge it with a standard 9V battery charger.

See more power options in the Power Supply & Adapters category under Shop, and pair it with Modules for portable builds.

Applications

• Multimeters and test equipment
• Smoke alarms and safety devices
• Microphones and audio gear
• Remote controls
• Toys and RC models
• Portable Arduino and DIY electronics projects

Frequently Asked Questions

Q: Is this battery really rechargeable?
A: Yes — the Double Charge 9V is a rechargeable battery. Recharge it with a standard 9V battery charger and use it many times over.

Q: Does the clip connector come with it?
A: Yes — the snap-on clip connector is included, so you can wire it into your project immediately.

Q: Can I power my Arduino with a 9V battery?
A: Yes — connect the clip’s red wire to Arduino’s VIN pin and black to GND. 9V is within the safe 7–12V range for the onboard regulator.

Q: How long does one charge last?
A: It depends on what you power — a smoke alarm sips power for months, while a motor drains it in hours. The rechargeable design means you get hundreds of uses from one battery instead of buying new ones.

Q: What devices use 9V batteries?
A: Multimeters, smoke alarms, microphones, remote controls, guitar pedals, toys, RC models and DIY electronics projects.

Q: Where can I buy a 9V rechargeable battery in Pakistan?
A: Right here — QKZee Technologies stocks it at our Hall Road, Lahore shop with Cash on Delivery across Pakistan.
