Nice battery that works well

works great as expected, charges quick good value for the money

Stands up to the cold if it starts warm. Holds charge well!

Es muy buena

UPDATE: My initial review was five star but, after only a little over a year, and less than 20 minutes of use, I'm now only able to get less than a minute of runtime using this battery before it stops working yet, it charges within a matter of seconds when placed back in the charger. Fully charged, this battery only shows 20 volts using a multimeter. I sent an email to Metabo support two weeks ago but, unfortunately, I haven't received a response. The battery that came with my SDS Plus rotary hammer drill is also exhibiting the same degradation.I have 30-year old 19 volt Craftsman batteries that are still going strong so, this has me questioning my decision to continue purchasing Metabo tools, especially cordless ones.I have a 36 volt SDS Plus rotary hammer drill and was using it to remove some cement but, after 30 minutes of some drilling and chipping the original, fully charged battery depleted. Since I have other Metabo cordless tools I thought I should buy a replacement to have on hand.(Old review) So far, I've been very impressed with all of the Hitachi and Metabo products I've purchased in the past and would certainly recommend them to anyone needing quality, affordable corded and cordless power tools.

These are genuine metabo 4/8ah batteries. When you use them In a 18v tool youd have a hard time using all the battery in a day even as a pro like me. I use them in power hungry metabo 4000 lumen work lights on medium brightness for 8 hours and they still have some battery left at the end of the day.

Works great and adds lots of power to tools that are heavy on power draw like sawzalls and multi tools

I have a number of Hitachi/Metabo OEM batteries. I only buy if Ships & Sold by Amazon. The brilliant Hitachi 3.0ah batteries were flat out the best because of the quality Samsung 30q cells that were used.I just bought this 8/4ah 36/18v Metabo battery and put it on my OEM 8amp charger. The several first attempts to charge the battery out of the package (having a one light charge) rendered a purple light (defective battery warning). After several attempts the battery began to charge and 30 min later, the charger light turned green (charging completed). However, the battery would only charge to 3 bars no matter how many times I tried. Defective. Not what I've come to expect from the green line of tools, that have been fantastic. QC needs to be stepped up, these batteries are not cheap.
