BABAKA2-Pack 3000mAh 20V Battery Replacement for Worx WA3520 WA3525 Battery for Worx WG151s, WG155s, WG251s, WG255s, WG540s, WG545s, WG890, WG891 Cordless Tools Battery

This is a follow-up review. Using a Worx WG545.1 blower, I checked the run time between the 2 original Worx batteries (20v, 2.0Ah, 36Wh) I replaced with these new batteries (20v, 3Ah, 69Wh). Both old batteries ran for 12 min. each. Surprisingly the newer, higher amperage and wattage batteries only ran for 9 min. and 10 min. Using Worx WA 3742 charger the Worx batteries took 4 1/2 hrs to recharge. The newer batteries took about 4 hrs. to charge. This test confirmed what I had experienced using the new batteries since June. What a disappointment. These new higher amperage and wattage batteries don't hold up in actual use. I was very slow to realize this and way past time limit to return so I am stuck with 2 batteries having a great right up but really poor real world use.UPDATE: The company was kind enough to send me 2 new replacement batteries, weather has been cold and wet so I have not been able to use them in blower or weed-eater. Really a nice touch though to care enough to send be replacement batteries.

I replaced the 2 standard Worx 1.5 Ah batteries that came with the blower and trimmer with these batteries. Either the power waned over time on the old batteries, or these new batteries are a significant improvement! The trimmer does a better job of edging, the blower has quite a bit more power.When the 1.5Ah batteries were new, I could finish the trimming right before the battery died. I would then use the other battery for the blower, and it was a 50/50 shot whether I finished or came up a little short. I have yet to even notice the batteries starting to fade in completing either task.These work with my old, standard Worx charger. So far so good!

I bought 2 replacement batteries after using the 2 that came with my Worx weekender and blower 5 to 6 years. The originals still work but don't hold a charge like they used to so thought it was time to replace them. I see other reviews saying these do not work as well as far as holding a charge but the manufacturer says they have to go through 3 or 4 complete cycles of charging and discharging before they reach their maximum run time. Makes perfect sense to me. I'm very happy with these batteries and the price is so reasonable

Be aware that these batteries must be used/recharged through 3 charge cycles before they can be used efficiently. Also it is best to charge them when they are cool and not hot from use. Otherwise this is an excellent battery/excellent product and this company stands behind their products in every way.

I am totally disappointed in this product. The two batteries I received don’t work at all. When fully charged they have nearly no power and stop working after just a minute with my Worx trimmer. I really need backup batteries, but these failed miserably.**REVISED REVIEW** I was contacted by customer service about the problems I experienced. The person I worked with was incredibly responsive and apologetic and totally honored the warranty. They replaced the batteries immediately and the replacements are working just fine. While they don't seem to hold a charge as long as the original batteries that came with the weed trimmer, they are pretty good and a good value. I wish to change my original rating from 1 star to 4 stars.

After having difficulty with one battery in my original order, the vendor quickly contacted me and offered to send replacement battery. This new battery functioned flawlessly. I appreciate their quick response. I will not hesitate to buy from them in the future.

I was paying $70 each for these batteries that I use on my leaf blower, the name-brand ones. These batteries seem to be more powerful and work for a longer time AND cost less than one quarter of the price of the name-brand batteries. Like them so much that I bought two more!

These batteries are far better than factory and last at least five minutes longer or use them for my leaf blower
