Review: After market to the rescue - Right price, better than my originals, holds charge and gets the job done
Review: Good price point/comparable to brand charger - Have had for about 6 months now with weekly use. Able to charge on my Worx charger. Bought it because the original batteries that came with my lawn mower don't last the entire mow. About 3/4 of the way done with my quarter acre property, I have to change the battery out. The same is true of this set if I start with them. I assume that they are lasting what the length of time they are supposed to last. Would buy them again. Don't need to buy a charger if you have the Worx charger.
