These rechargeable Lithium INR 18650 batteries are an excellent replacement for more expensive ICR 18650 ones. The difference is in composition (ICR ones contain Cobalt and INR ones contain Nickel inside.)

You can use these batteries to replace dead ones from your indoor and outdoor solar lights, even if the original ones were ICR. You can also use them for solar science fair projects involving solar cells and panels, for building an off-grid solar power system for camping, RVs, household appliances, doorbell cameras, and more.

You can connect multiple batteries in series to get higher voltage or in parallel to achieve higher capacity.

Use it in any device that requires a standard 18650 Lithium battery cell.
