  • Not a 4 amp hour battery
I bought these because of the price. i run a worx 2 gallon wet/dry vac and a weed eater with them. i have a worx brand 4 amp hour battery and when it is installed on my weed eater i can do my entire lawn on that 1 battery. with the ELEFLY 4 amp hour battery i needed 2 batteries to finish my yard. this is equivalent to a 2 amp hour battery. it is also the same size as a Worx branded 2 amp hour battery. the 4 amp hour batteries are much larger. On a positive note, for the price i paid, this is a good price for (2) 2 amp hour batteries. if you truly need a 4 amp hour battery, these are not the ones to buy. ... show more
