I was only able to mow about half of my yard with the 5.Ah batteries that came with my mower, but using the 8.Ah i was able to complete my entire lawn on one charge. I will say that the 8.Ah are quite expensive, actually cost more than my entire mower.

Purchased this battery for my WR342 Vision Cloud 4wd robotic mower. Has extended the cutting time significantly and I am satisfied with its performance and quick delivery. Would highly recommend.

I like being able to always have a spare battery on hand when the one I'm using needs charging. The 8.0Ah are my favorites, lots of power and a long lasting charge. Great value.

Great product, saves time upon working.

[This review was collected as part of a promotion.] [Employee of worx] The battery just doesn't stop. You will want to stop before this battery wants to stop. It's a BEAST. Ive used it on the 20V Leafjet and it just crushed the runtime of a regular 2 amp hour.

Purchased two 8Ah batteries to use with my 21" Nitro Self Propelled 40V Mower. I couldn't be happier with them. I have a third acre lot and had to change batteries before finishing. Not anymore though. I still have power left over to use with the string trimmer, edger, and 40V nitro Worx blower. All I can say is if your changing batteries or waiting for them to charge up again to finish the job, then get these batteries. You will thank yourself later.

I think these are good batteries overall but they're way too expensive. I would recommend for your Worx tools.

For some reason I can easily get my front lawn mowed with two 5 amp hr batteries so I expected to be able to mow the front and the backyard (same size) with two 8 amp hr battries. I run out of battery when 3/4 done on the backyard so these batteries do not appear to preform as rated.

Did not fit any of my tools that are some of the earlier models.
