CREABEST 2Packs 18V 2500mAh Li-ion Battery for Worx Replacement Battery WA3512 WA3512.1 WA3512 WA3511 WX163, Also Compatible with 20V Worx WA3520 WA3525 Lithium Battery Pack

Lasts longer than the OEM battery. Great purchase!

This is a great product to buy. The batteries work very well for the leaf blower that I own. Last a very good amount of time on full charge to get the job done. They recharge quickly and easily.

Perfect fit for my WORX WG151.1 trimmer and charger, which uses WA3512 batteries. I use this tool exclusively for edging around my driveway and sidewalks, as my yard is 3/4 of an acre, so I also have a gasoline engine-powered weed eater for the rough stuff.Like the originals, these Creabest batteries are 18v Li-ion. But, they are rated at 2500mAh, while the original is 1300mAh. This seems to have greatly improved battery life as I'm now getting a solid 45 minutes or more out of the tool, while about a half hour was the best I could hope for with the original battery, even when it was brand new. Now, I have no problem completing all of my edging on a single battery, with power left to spare.There's only one “Con” regarding this product: As several reviewers have pointed out, I noticed the Creabest label was totally covering the battery vents. I would however definitely NOT remove the entire label, as you may want to reference the specs listed at the top of it in the future. I simply took a box knife, made a cut in the label just above the vents and removed only that portion, which peeled off very easily with no residue (see photos). Luckily, the bottom part of the label covering the vents contains only symbols for various standards, which are pretty much useless to the average layman anyway.The 2-pack of these batteries is a huge bargain, especially given their performance so far. IF you can even FIND an original WORX WA3512 battery in a home improvement store, just one of them will easily run you more than the price of the 2-pack offered here.One star deducted for the label issue... Even though it's easy to fix as I have just described, it can result in the battery overheating (especially in high outdoor temperatures, I live in Florida) and as a result perhaps a shorter charge life as well. Other than this, I'm very satisfied with this product.* Note: I strive to write concise reviews with honest opinions to assist you as a potential buyer, and receive no monetary compensation for doing so.

Hey ... when the battery came I charged it and then put it right to use. This battery works great - better than the original! It provided strong output and ran longer than the original - I ran out of stuff to edge !!

The battery didnt fit correctly on my weedeater. Should have bought the replacement brand

Can't beat the price compared to the Black and Decker OEM battery. As another reviewer said, it does fit a little more loosely in the weed trimmer, but that is not a problem at all.

Needed longer battery life to add to the battery we all ready had for our weedeater. Works great. We can make it around our whole property now.

Good fit, plenty of power, will buy again.
