DSANKE 80V 3.5Ah for 𝐊𝐨𝐛𝐚𝐥𝐭 𝟖𝟎𝐕 𝐁𝐚𝐭𝐭𝐞𝐫𝐲 KB2580-06 KB280-06 KB680-06 KB3080-06,Real High Capacity Rechargeable Lithium Ion Battery for Kobalt 80V Cordless Power Tools Kobalt 80V Battery

Worked as expected and got me out of a Kobalt jam. Thank you.

Battery works great. The first one had issues but the seller resolved it and I have been using it for months. Same quality as OEM and I wouldn’t hesitate to purchase another one. The battery lasts just as long as OEM. Give it a try

I picked one up for around $50 on the Black Friday sale to experience a generic battery. Overall it's been a good battery so far after about a dozen cycles. Compared to my Branded batteries, it fits my equipment well, provides good power, and charges well. However, it gives within about one minute of the same run time as my Branded 2.5Ah batteries, so that's the realistic capacity. It also weighs 15g less than my Branded 2.5Ah batteries, which really says something about the reality of its labeling! Don't hesitate to grab one, but only if it goes on sale!

charged overnite after receipt. used it for a 12'x20' patch of grass, then batttery died. did not use it again for 2 months and even after full charge, it did not work. charged it again a full 24 hrs. , and did not work, even though the LED light show full charge. charged it a 3rd time , and still no good. took apart my electric lawnmower and tested everything else and determined its the battery that is defective. i have contacted vendor today and hope they will replace it with new one.

**Edit** I'm giving a 5star rating now, because the seller stands behind the warranty and IMMEDIATELY sent me a replacement. I was blown away it came the next day! Thank You!I bought two of these 80v 3.5Ah batteries together. One of them works great, but the other is totally dead.When they first came, I charged both of them, but due to weather I didn't use the kobalt tools for a month or so. When I went to use the chainsaw one worked great, but the other won't work, charge, or even light up. Now I missed the return date. Ugh.

Stopped charging after less than a year.

Good replacement for 80V Kobalt saw, weedeater and blower. Much less expensive and works great

workd great
