Other Thoughts:I bought 4 Lithium Ion 17670 batteries. The batteries are very good on quality. Because this is Lithium Ion type battery which is widely used on cell phone and laptop, we have to beware on charging and discharging. Usually, this type Lithium Ion battery can be charged around 1000 times. I will buy this battery again.
Other Thoughts:I bought these batteries thinking it will make a big difference in comparison to the regular batteries 17670 I usually buy from China at much better price.......
<br/>it is the same thing. I think these batteries were a little stiff in price.
<br/>They work the same as the ones I have.
Other Thoughts:very very happy over these bateries, came with full charge and very impressed with run time. BUY them they have a high 2800mAh. Beware of others at a larger mAh and will be too large they will not fit in some lights.
Other Thoughts:I got these to use with a flashlight and they work great. Have seen complaints about using multiples and them not fitting properly but I have not had any problems at all. They are snug, but that is a good thing. Great batteries.
