Batteries won't charge
After purchasing the combo pack from Lowe's and charging each of the 2 included batteries for 12-hours plus each, I used both batteries to trim the weeds in my small yard. After finishing the job, both batteries now flash RED when I put either on the charger. From previous reviews, this sounds pretty typical. Guess I will wait to see if they will charge once they cool. If not... back to Lowe's they'll go. Fortunately, I live across the street from my neighborhood Lowe's. :-)

Good Battery
I bought this to have as a back up for my B&D blower which only came with one battery. Fortunately, I was able to find this at CPO at a great price! The second battery is a must when you have a larger deck and a long drive way with trees nearby. These batteries hold a charge well when not used and last a good amount of time when working with better power than my old 18V NiCad unit.

20V power tools are better than 18,12 or 6 volt products. Lithium batteries are better than other batteries. Easy to charge, "no" memory, Can recharge anytime. Great product

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 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,

what does a blinking red light mean when charging
chyaz on Sep 10, 2014
BEST ANSWER: Long and short blinking red light indicates a 12+ hours charging time is recommended. A quick blinking red light indicates the battery will not take a charge. However, Li-ion batteries should be charged as soon as they power out, but if they are warm you may see the blinking red light. Let the battery cool before charging and try it again. If it continues to blink red it's time for the recycle bin.
For long life Remember this with Li-ion batteries; They like to be charged and don't like being run too low. So when your tool quits DO NOT try to use it until it gets a good full charge.

I charge my battery fully every time but charge only last about 30 mins. and this is a new unit, just got for Christmas and just started to use. Very disappointed!!!

None on Apr 9, 2016
BEST ANSWER: Run times for the battery are going to vary depending on the tool it is being used with.
We have two of these. Using them on leaf blower and hedge. Neither lasts more than a few minutes. Recharge time is six times longer. What could be wrong? Our view is they are unsatisfactory.
Bob on Feb 14, 2016
BEST ANSWER: The LBXR20 is a low amp hour compact battery. Both applications you are using the battery for require a large draw so you are sapping the battery very quickly. The model LB2X4020-OPE battery would increase the run time between charges
