DTK Replacement for Greenworks 80V Battery Ion Cordless Power Tools 80 Volt Batteries 2500mAh

I have a very old Lenovo Edge 15 whose last replacement battery decided, for no apparent reason, that it was time to die. I order a replacement by DTK. It arrived almost instantly, well packaged, in perfect condition, and with excellent instructions on how to train a new Li-Ion battery. My new battery snapped in perfectly, and fit like a glove. I allowed it to fully charge before booting up for the first time. Upon logging in, my battery indicated more than 4 hours of life on this first charge. That has NEVER been the case with this computer. I don't think I've ever seen 3 full hours on the meter. As instructed, I let it run until the battery drained to 7%, then fully charged. Again, flawless performance. Considering that this battery cost less than half the price of the first replacement battery, which had a lower capacity, I cannot find any room for improvement.

I was skeptical, but this battery seems to perform better than the original batteries did when they were new. I've only had it for a few weeks, so I don't know about longevity. Because the price is so much less, I was going be happy even if it was only a little bit behind the brand name battery.

This is a good product for the money. It works as advertised and is simple to install. My one critique is that the battery life is shorter than my former. The new battery lasts at best 4 hours whereas the original would last 5 to 6.

Works well. Easily edges the whole house multiple times on one charge.

About half the life of the standard battery. Usually lasts about 15 minutes for me.

This battery is a 1 for 1 swap with the original Greenworks battery. The only difference is the battery inserts upside down to the Greenworks battery. (That's probably how they got around design infringement.) We have just used it a few weeks but it has been working great. And it works with the Greenworks charger with no issues (just the upside down orientation - I think you can live with that!

charge wont last long

This was purchased as a backup battery for the Greenworks cultivator. It does work, but my husband found that if he hit a rough patch and the cultivator jerked around the battery would pop out. It does not stay in place as securely as the Greenworks battery, but it is cheaper. So you have to decide if you want to save money or spend time putting the battery back in place. It probably pops out of place because it is a little bit different shape than the official Greenworks battery.

My battery lasted just barely over 1 year. I started noticing less charge at about 14 month, just after warranty. It didn't make it to 2 years, it says 0% and gives red battery error. Need a new battery since a few months. I think I did reach out to them after warranty. I will try my luck with an other brand.
