These are NOT Vape Batteries!

Do not attempt to put these in a vape, they will get stuck and leave your vape unusable, don’t be dumb like me! The batteries may leak or corrode over time, potentially damaging other devices or surfaces.

Pros
  • The USB rechargeable feature is convenient and saves money on purchasing disposable batteries
Cons
  • The batteries may leak or corrode over time, potentially damaging other devices or surfaces

Fatter and Longer for my opinion

Not too long ago, I started to switch my flashlights from CR123 powered lights (batteries are too expensive and hard to find) to AA powered lights (plenty bright nowadays, and inexpensive and easy to find batteries). Then, with 18650 powered lights becoming abundant, I started to switch some of my lights to that.These batteries with a micro USB charging ports are great for while traveling. I have an 18650 battery charger, but it doesn't go with me places, so being able to charge the battery…

Pros
  • Support 1500+ cycle recharge, 12 months warranty, Please Note: Size 18.5mm*70mm(± 0.3mm)
Cons
  • The batteries may not be easy to find replacements for if needed

These would not light flashlight

They simply would not light my Trustfire T70.No good sent them back for refund, have not received it yet. The battery charger may not be compatible with other devices, making it a single-use product.

Pros
  • Good for a battery replacement
Cons
  • The battery charger may not be compatible with other devices, making it a single-use product

Solid battery. Works as advertised! Easy recharge.

I really liked the color led from red to green indicating fully charged. A simple matter, but helpful and useful. Nice quality and comes with a lil holder. Micro usb wire not included.

Pros
  • Excellent
Cons
  • The batteries might not actually fit in the Klarus flashlight

Amazing little battery!

It’s been three months since I’ve had to use my edc flashlight. I used it the other day for over two hours continuously and I only used up a fifth of the battery life! I haven’t had to recharge yet! Great battery for the money!

Pros
  • Creo que bueno, apenas lo estoy usando
Cons
  • The batteries may not provide enough power or lumens for the Klarus flashlight, rendering them useless

Not Good at Holding a Charge

I only use my flashlight 5 to 10 min a night while walking the dogs and the battery only holds a charge for 24 to 48 hours which doesn’t seem right to me. Also I’m not on the highest power. Very disappointed.

Pros
  • Quality battery
Cons
  • The batteries may not fit other devices, limiting their versatility

Works great. on my review.

Much better than the rechargeable batteries that came with the flash lights. They hold the charge longer and charge quicker.

Pros
  • The USB charging feature eliminates the need for a separate charger, saving space and reducing clutter
Cons
  • The batteries may not be well-suited for outdoor use or rough conditions, limiting where and how they can be used

Replacement for Klarus XT12

These batteries work great for the discontinued Klarus XT12. A little longer than a regular 18650. The micro usb charging port is a nice addition.

Pros
  • Needed battery for my flashlight. It fit and worked as expected
Cons
  • The battery charger may be bulky or difficult to transport, making it inconvenient for travel

Great replacement battery.

I received these and one wasn’t working. Contacted the seller and they shipped me a new set within a day. Great seller. Highly recommend them

Pros
  • The 3.7V voltage is ideal for powering high-performance flashlights
Cons
  • The batteries may be incompatible with other devices due to their unique specifications or design

Terrible. Took forever to charge and then refuse to hold one.

Useless. Love the idea of a built-in USB port (and LED to indicate charge status), but it didn't go green until a VERY VERY long time on the charger, and then wouldn't actually light the flashlight. Terrible product, very sad.

Pros
  • Both work well so far. Time will tell how they last
Cons
  • The battery chargers may be difficult to use or set up, making the user experience frustrating

18650-type 3.7V Button Top Batteries USB Rechargeable Battery 3600mAh

Excellent product. Great capacity and durability!Updated: Requested a replacement since the original order contained defective batteries. They replaced the order quickly and the new batteries are working correctly.

Pros
  • These batteries are a great value with a pack of two included
Cons
  • The batteries may not be easy to replace if they malfunction due to being sold in a two-pack rather than individually

Cons

Cons
  • The charger may require additional adapters or cables to function properly with different outlets or devices
