    I used this for my kids power wheels. It last a long time in comparison to the battery it came with stock. Kids can now ride it for many hours. Just had to cut off the factory plug on the car so it can be connected to this battery.

    Fully charged when received. Measurements are accurate for overall size and for terminals. Have not installed (seasonal outdoor equipment – chipper shredder vac electric start) so cannot comment on holding charge and recharging and starting capabilities, but do not expect any problem with sealed lead acid battery. Hope to have 7 years of good use out of it. I do store it indoors between seasons.
