20V 6.5Ah Replacement Wor 20V Battery and Charger Starter Kit, for WA3525 WA3520 WA3575 WA3578 20V PowerShare Battery, for 40V (2X20V) Tool + WA3742 Wor 20V Charger

Purchased this larger battery for my weed eater.

I bought this for my husband, he was really impressed.

The battery arrived partially charged and I finished charging it with the enclosed charger. The charger worked well and everything worked as it should during the charging process. The light on the charger flashed green when plugged in and turned red once the battery was connected and then, the light turned solid green once the battery was fully charged. I checked the batteries LED charge indicator and it showed the battery was now fully charged.I tried the battery out on my WORX Switchdriver and everything worked as it should with no problems. After a few hours, I came back and tried the battery again. The battery still showed a full charge and the drill worked as it should. I came back the next day, battery still showed full charge. I drilled some more holes and drove in some more screws and then removed the screws and after some time of use, I checked the battery again and it still showed a full charge. The battery worked well and held a full charge even after using the drill multiple times. I am satisfied with the battery and chargers performance and think this kit is pretty good quality.

We have had Worx tools for several years. We finally replaced our weed trimmer this year and only purchased the tool since we had several batteries. Some of the batteries are getting older so when I saw this I thought I would give it a try. The battery came with a partial charge but I charged it fully before using. This is the same voltage but has more amps than our older batteries. My son was able to trim the entire yard (house on an acre) and still have charge left. He usually comes in at least once to change out the battery. So it saved time and worked great.
