### ⭐⭐⭐⭐⭐ Satisfied

### ⭐⭐⭐⭐⭐ Great for price
*by J***L on January 17, 2026*

Greatly appreciated, for fast delivery and good quality of product and service.

### ⭐ Mislabeled batteries!!!
*by G***R on December 29, 2024*

I purchased quantity 4 of the alleged 2800 mAh 16340 lithium-Ion batteries. They actually have a tested capacity of about 300 mAh. I had to give them the minimum rating of one star, but I feel that they aren’t even worth that. I was suspicious of them, as reputable battery stores don’t offer 16340 Li-Ion batteries over about 900 mAh capacity. So, I ran a battery test on them to determine the real capacity. The battery test consisted of three steps: 1. Charge the battery to full charge. 2. Fully discharge the battery. 3. Charge the battery to full charge while measuring the charge current. As can be seen in the photo, the battery tester indicated that each battery had a measured capacity of about 300 mAh. I repeated the test 3 times, and received similar results each time. To verify my battery tester, I tested a brand new 680 mAh RCR123A Li-Ion battery purchased from a reputable battery store. As can be seen in the photo, the test indicated a capacity of about 750 mAh, which is better than what the battery manufacturer claims. I will be contacting the seller to obtain a refund for the mislabeled batteries.
