Review: Must have battery for Black & Decker saws and outdoor equipment - We have the entire grouping of Black & Decker 20 volt hand tools and outdoor equipment. Drill, impact driver, circular saw, saws-all, LED flashlight, chainsaw, hedge shears, weed trimmer, blow, pole chainsaw. The 1.5 amp hour batteries that come with the tools work fine on the drills and flashlight, but this battery is a must have for the rest of the tools and outdoor equipment -gives many times the battery life than the 1.5 AH.
Review: Powers my circular saw, now I don't need to replace my tools. - I bought this back in March of 2016 and 9 months later I really want another one. This gave my Black and Decker tools new life. As expected, my Matrix series drill and another B&D drill both last longer. They don't require huge amperage to get their work done, so the difference wasn't seen there. The HUGE improvement was on my B&D circular saw. So back in March, I was debating whether to buy a new system of interchangeable battery cordless power tools like DeWalt which cost a decent amount more but deliver more power. I decided to give this 4 amp battery a try and test it against the 2 amp batteries that came with. With the 2 amps, my circular saw didn't have enough power to cut through anything wider than 4 or 5 inches; instead, the blade would catch between the pressure of each side of the board I was cutting. The circular saw powers through using the 4 amp battery and I was able to build a 20 foot by 4 foot bridge across a creek in my yard - constructed mostly with 16 foot 2x16 boards. Battery is still going strong and no signs of decline that I can tell. I have two drills (one Matrix, one regular) and the circular saw. I want at least one more but would love to have one for each of them. I've settled that I don't need to shell out the extra cash for higher-end tools... I'm just a home DIYer and Black & Decker is fine for my purposes.

## Features

## Questions & Answers

**Q: how long  will this battery take to charge with the B&D quick charger?**
A: According to my Black & Decker owner's manual, and depending on the exact model of your quick charger, the fastest charge time for the LB2X4020 is 2 hours (that's from 0% to 100% charge).

**Q: Can you charge a black+decker lb2x4020-ope 20v 4.0ah lithium ion battery pack using a black and decker lcs1620 charger?**
A: This battery fits the charger that came with my hedge trimmer and my string trimmer.

**Q: Will this fit on my Craftsman Bolt-On? As I understand the B&D Matrix is the same as the Craftsman?**
A: Yes, but make sure you buy the the 4020 4.0 battery. 3rd generation of lithiums.

**Q: Will this battery run my older 18 volt Black and Decker tools?**
A: Nope. 18 volt is not 20 volt. The companies change voltage periodically to sell new tools. They also don't want to make the batteries interchangeable between brands for the same reason.  If by chance your 18 volt battery is still Nicad, a switch to Lithium Ion is really worth the cost. Just pick the brand you can live with long term for all your tools.

### ⭐⭐⭐⭐⭐ Delivers on whats promised
*by N***L on March 1, 2025*

There’s not really too much to say. The battery charges fully, though it does take a while because of the capacity. It holds its capacity when not in use. And it delivers consistent power appropriate to the size. It’s definitely nice not swapping the batteries out as often
