Question: What is the differance between Black & Decker LBXR2020-OPE 2.0 Ah Lithium Battery Pack, 20-volt?
Document: I bought 2 of these for my Black and Decker 20V Max Lithium Ion Pole Pruning Saw. They last 33% longer than the basic LBXR20 1.5 Ah battery that comes with the saw. This LBXR2020-OPE battery is 2.0 Ah. Makes it easier to get the job done. These sell for only a few dollars more than the basic battery, making them a good deal, relatively speaking.
Not impressed! I have to use 4 of these 20 volt lithium batteries to trim and edge an average sized yard. Then it takes 8 hours per battery to recharge.
I would have to say for the money it is best to just go with the 4.0 Ah battery that B&D offer. This one lasts longer then the normal one, but in my opinion it is not worth the $50.00
The entire Black and Decker cordless series is good for LIGHT duty work. It's reliable and easy to use. You will need multiple batteries so an extra one or two or three or more does the trick.
The best thing about Lithiums is they hold a charge on the shelf. They also don't have the memory issues that NiMH batteries have. Lithum is the way to go.I purchased some charge markers, a big help keep your discharged batteries marked for charging later!battery charge tracker and reminder for Dewalt / Black & Decker / Bosch / Makita type batteriesHappy Shopping!
Bought a 2nd battery for the B&D drill I purchased. It has higher capacity and wanted to have 2 batteries so I could have one charging. It holds a charge for a long time much longer than the Ni-cd battery drill I replaced.
Great having a spare battery. Jobs are completed much more quickly.
Very good battery life .. so far , if the charger and batteries last this product can be considered an actual tool
Extra oem battery. Delivered when they said. Works great. Happy with purchase. Would purchase again in the future when I need more batteries.
Last much longer that the battery it replaces.Battery is 40wh compared to 30wh on other battery it replaces.I beleive they make a HD model
