Lot of great reviews here.. But..
Loved the unit when working, but I have three batteries and they will NOT charge. Attch to battery, plug it in outlet, after a second it goes green and then immediately starts flashing red. Batteries were cool, not warm or hot. All three, same issue.

Describe Yourself:
No More Power Cords For Me!
These batteries are not short on power or ability. The tools they are used on have also been designed to make the best use of these batteries. Having used power tools to make a living, the Black & Decker 20 Volt Max System has impressed the h--- out of me! Originally I bought the 20V MAX* Lithium 10 in. String Trimmer / Edger for lawn upkeep and excitedly charged the battery overnight, set out the next morning to trim and edge my lawn and when completed my neighbor came over to see it and as it still had a charge left I let him borrow it and he got his done. When he was done and brought it back there was still a charge on it! I then bought the MATRIX™ 20V MAX* Lithium Drill/Driver along with the MATRIX™ Oscillating Tool Attachment and MATRIX™ Router Attachment. Because of all the negative revues on these batteries I also bought the Black + Decker 12-20V MAX* Lithium Fast Charger and an extra battery. Used that drill and attachments all day long Saturday for a couple of projects around the house and never did have to swap out the battery for the extra one. By this experience I can safely say I did not need to buy either the fast charger or extra battery. I have determined that many of these reviewers do not know how to properly handle and use power tools and are most likely abusing them, expecting way too much out of light duty use tools and consequently draining the battery fast. I am sure that is why their batteries get hot which will quickly shorten the lifespan of that battery. Mine never even got warm that I could tell. No more power cords for me!

Decent battery
They last about 15-20 minutes depending on the tool used and how it's used. Which is adequate for average household chores and projects. Battery powered tools shouldn't be used as a replacement for their electric and gas powered cousins for large projects.

Priced right
The battery seems well in position when mounted on the tool, but there's a space between them at the back side about 1 mm.
It gives the illusion that the battery isnt well seated.

I just purchased the trimmer, leaf blower and hedge trimmer combo. First time charging the batteries: first kne was fine, came to full charge withjn a couple of hours. Second one show fast blinking red light. It's been kn the charger for 12 hours.
The owners manual does not mention red light function, only green. Is it true that fast blinking red lights mean this battery won't take a charge? If not, what's the error message?

What does blinking green light mean when chargin 20 v lithium battery?
Kate on May 23, 2016
BEST ANSWER: Blinking green is charging and it should continue until fully charged and then show solid green.
What amp-hour rating is on this Li-ion 20V battery?1.3Ah/mAh,1.5Ah/mAh,or 2.0Ah /mAh.
I noticed on your specifications drop-down box that the VOLTAGE is given BUT NOT the AMP-HOUR rating (i.e:the higher the Ah/mAh the LONGER-USEAGE the battery
offers before recharging is needed) & it gives buyers a reference for comparing a particular battery on the true cost-VS-runtime basis? (Y a 20V 4.0Ah costs so much than a 20V 1.3Ah battery)Thank you,
??????????G8R George??????????

What does flashing light mean?
A shopper on Jul 2, 2017
BEST ANSWER: I've had this issue for some time. Flashing red does not necessarily indicate low charge. Can also be error, and battery will not charge.
