Step 1 – Assemble and Charge

Ever wonder how a battery is made? Me neither, but it’s actually quite interesting. The first component of the battery is the ABS plastic shell. We then insert our very own lead plates and glass mat separators into the shell before filling with acid. The batteries are then capped, sealed, and charged to complete the process.

Step 2 – Assess for Quality

The next step in the process is that of quality control. We don’t make great products by accident. Our inventory is carefully controlled by strict quality assessments that must be met before qualifying for shipment. Our products undergo voltage tests, weight measurement, and psychology tests to make sure they are physically and mentally sound.

Step 3 – Pack with Care

We’ve all gotten that package delivered in the mail that was clearly marked as ‘fragile’ but looked like it was used as a football by the delivery man. That’s why all of our items are packaged with the customer in mind

Step 4 – Deliver On Time, Every Time

Your order is not completed until the item is in your hands. After all, what good is a great product if it doesn’t get to you in time? When your alarm is screeching ‘Fix Me, Fix Me!’, you can trust that you won’t have to wait an eternity for your battery to arrive.
