18650 & 18700
Lithium batteries are a great option for today’s high end electronics as these cells typically have higher capacities than their alkaline counterparts. Although rechargeable batteries tend to cost a little more than standard alkaline batteries up front, over the long haul, these costs are reigned in because you won’t need to replace rechargeable batteries nearly as much as alkaline cells. Of course these upfront costs are lower when you purchase your rechargeable batteries at Battery Junction. Our selection of 18650 and 18700-sized rechargeable batteries from the Ultrafire, Titanium Innovations, TerraLUX and Tenergy brands are typically priced well below retail and in many cases, you can buy these batteries in bulk which lowers the prices further. We have just about every size of rechargeable battery that you need, with products including protected and non-protected cells. The protected cells feature a patented Internal PCB protection against under voltage and over voltage. These protected cells are best used in single cell applications because the protection is based on the correct voltage of a single cell.
If you attempt to bundle protected cells as a battery pack, this defeats the purpose of the protection. Battery Junction also has rechargeable batteries in stock that do not have PCB protection and these batteries are perfect for pack building. The bottom line is that if you are a remote control car or airplane enthusiast in need of batteries to build battery packs for these devices, or if you have a high-quality Nitecore or Fenix flashlight that you need to power, Battery Junction is your best source for very high-quality rechargeable batteries available at very reasonable prices with fast shipping on most items.
