### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    These are unprotected batteries
  

*by J***T on Reviewed in the United States on July 24, 2023*

If you want protected batteries (71 mm length), buy the 
  
KBT 2600mAh with PCB







  
  
     batteries in the blue sleeve.  These here are 65 mm length and are unprotected (they don't have the additional protection circuit in the bottom of the battery).  The product description is not clear on this, unless you convert the length shown in one of the graphics from 2.58 inches to 65 mm.  I did not pick up on this before ordering.  Otherwise they seem fine.  Ordered a four-pack.  All measured the same voltage out of the box, 3.907±0.003 volts, which is close to full charge.  Now to see how they behave over time, if the house doesn't burn down...

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    So far, so good.
  

*by G***M on Reviewed in the United States on January 9, 2023*

It is difficult to rate anything as far as durability and bang-for-the-buck when you have only had it for a short time. These are no exception. As stated above, everything is good for now. Check back in December 2023.

    Best battery to purchase !
  

*by A***S on Reviewed in the United States on July 25, 2023*

These batteries have been way better than previous batteries I purchased, they hold their charge longer and recharge with no problems. Will get 4 more . I work nights and use a flashlight to see out in our bus yard , they last for hours , on & off use . Very pleased .
