Cruzin Cooler 300W Battery Replacement Set

Does your cooler run out of juice in less than an hour? If so, it's time to replace those old batteries.
This listing is for a full set of 2 12Ah batteries, they are the exact same size and fit perfectly inside your 300W Cruzin Cooler.
We also offer an ungraded set of 15Ah batteries that are the same size, please see below
These batteries are manufactured by Universal Battery for Dunarri, and are the ONLY batteries we use in our own personal coolers - that's right the same ones you see us go on 20 mile runs in our YouTube videos! (We of course use 22Ah batteries in custom 60V packs).

Think all batteries are the same? Think again.
The amp hour specification and how batteries are rated is not well defined, and so many manufacturers say their batteries are higher capacity than you'll ever get out of them.
In addition many low quality batteries have a poor cycle life, meaning after less than 100 charge / discharge cycles your batteries could have as low as 50% the original capacity.
Besides capacity and cycle life, how much amperage the battery can deliver will give your scooter better torque and acceleration.
So if you're considering buying no name batteries to save a few bucks, just remember you don't know what you're getting.

We've tested several brands over the years and these are simply the best AGM batteries out there.
