This is my second battery from this Mfg. The Ryobi batteries are horrible and if you run them completely out of power they sometimes will not charge again! I do not have that problem with the Kunlun batteries and they last substantially longer than the OEM Ryobi batteries.
can't say enough good things about these batteries.

These batteries are great! I have purchased 2 and they both have had no issues. Hold a longer charge than the original ryobi brand. They also charge up great, very fast and work well with my original ryobi charger and have great power. Also much cheaper than buying name brand they are also not super heavy and easy to use. Would recommend!

Thunk About ItThunk About It:
3-22 UPDATE: Amazon Replaced The Bad Kunlun 40V 6Ah Battery, Bad News: It Tested Just As BAD!
Capacity Test Concluded Identical Results ~~VERY BAD~~ With The Same 63% Of Rated Capacity???

Luna, From Kunlun, Responded To My Message When I Suggested That They Give All Of Their Customers A 50% Refund Due To The Low Capacity Issues, "By Asking Me To Return The Battery To Amazon For A Refund And Then They Would Have It Examined"? I Wonder Why They Just Do Not Pull One From Their Stock Since They All Seem To Test The Same???
TESTED 40V 6.0AH BATTERY PACK WITH ELECTRONIC LOAD TO LEARN WHAT THE TRUE OUTPUT CAPACITY OF THIS BATTERY PACK IS AND IF IT IS A GOOD OR A BAD QUALITY PACK.
FULLY CHARGED THE BATTERY PACK ON A RYOBI CHARGER, LET THE BATTERY REST FOR 1 HOUR THEN BEGAN THE DISCHARGE CAPACITY TEST WITH AN ELECTRONIC LOAD AT A GENTLE LOAD RATE OF 2.00 AMPS PER HOUR. THIS TEST SHOULD HAVE TAKEN ABOUT 3 HOURS WITH A 2 AMP LOAD IF IT HAD A 6.0 AH CAPACITY, BUT IT FINISHED IN...

EDIT: Seller reached out and provided a replacement (thanks!). The new battery is holding up well so far and they provided some additional tips to help ensure this one lasts longer.
It's nice to have a second battery which is considerably larger capacity than the one my Ryobi multi-tool originally came with. Will update again in fall with how the new battery is holding up.
