Panasonic NCR18650B (Protected, Button-top)

21-DAY FULL REFUND POLICY
AUTHENTIC GRADE-A BATTERIES GUARANTEE

In addition to adding a button-top to the positive terminal of the Panasonic B, we have applied protection circuitry (a PCB also known as a printed or protective circuit board) for additional safety. Because of inherent limits on the amount of current electronics can regulate, PCBs are only applied to low-drain cells (cells under 10 amps).

This circuitry will protect you from several things, like short-circuiting, over-charge, and over-discharge. When your device does not have its own regulatory circuitry (like in the case of many flashlights), it is highly recommended you add a PCB.

Do you want a PCB, but not the Panasonic B? We can add protective circuitry and button-tops to any of our cells. Just send us a message. 

Button-tops and protective circuitry are ideal for flashlight users.

Battery Bro has your back

Never worry about quality when buying from Battery Bro. We make sure you have the latest, greatest cutting-edge battery, every time. 

Price

18650 batteries are commodity cells, and as a wholesaler, we understand how important price is to your bottom-line. As such, we offer international shipping directly from Asia to save money in higher quantities.

Shipping

We ship worldwide normally via UPS, FedEx (DAP), and Special Line (DDP) under Incoterms 2010.

21-day full refund

All battery cell orders fall under our 21-day full refund policy to allow ample time to test for authenticity and performance.

Quality guarantee

Battery Bro has been in business since 2014 and has never sold counterfeit cells. We value long-term relationships with clients and encourage our clients to performance test cells against official manufacturer specification sheets.

In Asia, 18650 batteries are binned by quality into A, B, and lower bins. C-bin batteries are often recycled from battery packs. Lower bin batteries will underperform and may be dangerous.

We will only provide A Grade cells, unless specifically required to otherwise, for example, some clients may prefer Grade B Chinese cells for low-cost ESS projects. We can also confirm batch-date code, run testing (like impedance/voltage/capacity), and handle other IQC requirements.

Some general tips

• Do not exceed max. continuous discharge ratings.
• Keep temperature under 60 degrees Celsius.
• Do not carry loose batteries in your pocket.

Free Safety Booklets

For retailers selling 18650 batteries: 

Increase battery sales and protect yourself from liability with 18650 safety booklets.

Customers ignorant to battery safety are not likely to purchase 18650 batteries or upgrade to MODs which require them.

You, the store owner can show your customers your shop cares about their safety

Simply bundle our safety booklets with the batteries you sell.

• Did you know? In 2015, an e-cig shop was sued for one million dollars when a battery short-circuited in a customer's pocket. A safety booklet could have prevented that and protected the retailer from a lawsuit.
