  • Battery is performing well.
Style: 2 PCS
Batteries arrived packaged in a small custom plastic box with a latch. Batteries had 3.4 volts when they arrived. I installed one battery in a small Bluetooth speaker that also has many LED lights and a lazer light. Installation required soldering to the battery. Battery had no trouble being soldered. Keep in mind that I do have professional soldering equipment as well as top of the line flux and solder. After installation I charged the device to full capacity. So far the battery has performed very well. We haven't used the device for an extended period of time yet so I'm hoping that the battery continues to do well. I've been disappointed by other batteries right out of the box. Dead on arrivals. This battery hasn't disappointed me in any way so far. I have no complaints at this time and I would recommend it to others. ... show more

  • Excellent for laser and flash lights
Style: 2 PCS
Bought these to use with a tactical laser light and in place of cell batteries. I already had a charger for them and it seems to work pretty good. At first it was hard to tell if these were button or flat, but they are indeed button. Granted they stand the test of time, I'll be buying again.

  • Batteries are important
Style: 2 PCS
The media could not be loaded. I lost my mini fan battery at Disneyland on 10/16. The new batteries arrived on 10/19. We are at Disneyland today (10/20) and these batteries are saving us! It’s hot!!!! I’m grateful for this purchase.

  • Batteries DOA - Possibly Used
Style: 2 PCS
Used an Industry-standard charger with full readouts: voltage, power, mAh... you get the point. I charged these batteries for 12 hours. First problem: They read out as "fully charged" at 1735mAh, not 3500. Likely a mislabeling, I thought. Annoying, but pretty common, right? Second problem: I switch from "charge" to "test" mode--IMMEDIATELY back to 0mAh. I tested them again in a backup 18650 charger, same result. Zero charge. This isn't even a case of "barely holds a charge for X-minutes;" they literally cannot be charged nor hold a charge. They're totally spent. Literally repackaged e-waste. Buyer beware. ... show more

I was able to use this product to replace batteries in my headlamp. The rechargeable batteries also come in a convenient plastic carrying case that can be used to store other little knickknacks.
