    but I know my Makita Charger did not like this battery
  

*by S***E on Reviewed in the United States on June 8, 2018*

I bought this product 6 months ago as a battery pack for my Makita Saw. It also doubled as a battery for my drill.  The first time I went to charge it gave me a weird flashing error on the charger, but it did eventually charge. Over time and attempts to charge it appeared the voltage was dropping while on the charger, it eventually dropped to 0v and now it won't take a charge at all.  Not sure how to prevent this, but I know my Makita Charger did not like this battery. I would not recommend this batter if you hope for it to last longer than 4-5 months.

    Too early to really tell, but so far it seems to work real well/
  

*by C***E on Reviewed in the United States on February 3, 2017*

So far so good. I love the voltage indicator, it tells much more than a couple lights, I have not run through several charge cycles yet so will know more later. The only thing I do not like is the micro usb connector with a cable adapter that you need when using the USB charge function. Why not just put a USB-A connector on it instead so you can plug a USB cable directly. If it had that I would give it a 5+

### ⭐⭐⭐⭐⭐ 







  
  
    Great product! Out performs all my other batteries!
  

*by J***Y on Reviewed in the United States on July 22, 2017*

This is a great battery! I've purchased other 5.0Ah batteries and they lost their charge quickly. This batterries charge last a long time and the voltage display is great the batterry actually charges to 20V. I have not used the USB port but it seem like a quality connection and adapter cord. I highly recommend this battery, I will be purchasing more in the future when I need replacements. Thank you Aoyan, great battery, great price.
