Highest Quality in Comparison - High Grade Cells
We have strict quality control because we manufacture our own batteries, unlike most battery websites that are selling random batteries from China. The chemical cells inside a battery can be categorized by 4 different grade types, ranging from low to high. We only use the highest grade cells for our batteries. Many websites are selling low grade cells and offer them at a cheap price. There is a problem with these cheap cells, your battery will die very quickly and you will have to spend money on a new battery again. Because of the high grade cells we use, we're able to offer a 2-year warranty. Other websites cannot offer this warranty because they know their batteries will die within 2 years. We're happy to offer a 2-year warranty because we have confidence in our products.
