    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.

Packaged very well with terminal bolts, washers and nuts included. Good looking product. Excited to incorporate it into my car audio system.
The Battery delivery 🚚 turnaround time was faster than I expected ! Now moving on to get the installation done by a Battery professional.
Perfect fit. Look forward using this unit often.
Good battery, perfect fit for the Toro Recycler push mower. Came well packaged and fully charged 12.76v. Model ML3-12. Photo shows all the packaging.
Super easy install, less than one minute.
Beeping stopped immediately
The one I replaced today was 3 years old with no issues. It finally gave up. Trying another one. Hope to get the same outcome.
Arrived in great condition and will now extend the life of our Pathfinder 320 speaker, Whoo, hoo!
Got mine on Amazon and it got here quick, I got it installed and running. Thanks again
Arrived as promised, in perfect condition. Installed and cranked up the mower fast. Great price.
Second set I have ordered, these have been very good batteries especially at the price point charged. No problems whatsoever with them!
