Product Description:
Is your electric shaver or toothbrush not holding a charge anymore? Bring it back to life with our premium 14500 3.7V 680mAh Rechargeable Li-ion Battery featuring Center Solder Tabs (2-Pack).
This is a specialized DIY replacement cell designed for devices that require centered welding pads. The battery comes pre-welded with sturdy nickel tabs conveniently located in the center of both the positive and negative terminals, fitting perfectly into compatible electric shaver and toothbrush mainboards.
With a genuine 680mAh capacity and reliable 3.7V output, this high-quality Li-ion cell ensures your grooming tools run at peak performance again.

This is a Flat Top battery with Center Solder Tabs. It is NOT for flashlights or standard battery compartments. A soldering iron is required for installation. Please check your original battery carefully: If your original battery has "7-shaped" (offset) or "U-shaped" solder tabs, this battery will NOT fit. It is strictly for center-welded applications. Please also check the polarity before welding.

FAQ:
Q: What is the difference between "Center Tabs" and "Standard Offset Tabs"?
A: Center tabs mean the solder pads are located strictly in the middle of the battery's length. Offset tabs (7-shape) are located near the edge. These two types are NOT interchangeable. You must buy the exact tab position your device requires.
Q: Do I need special tools to install this?
A: Yes. You need a soldering iron and basic soldering skills. The battery comes ready with tabs, so you just need to tin the PCB pads and solder the tabs directly.
Q: Is this battery protected?
A: No, this is an unprotected cell. It relies on the charging and safety circuit built into your electric toothbrush or shaver.
Q: My original battery is blue/purple, but this is green. Is it compatible?
A: Yes, the color is just the outer PVC wrap which varies by factory batches. As long as the size (14500), voltage (3.7V), and tab position (center) match, it is the correct battery.
