Typical bad mouthing a company which clearly offers a superior product and/or warranty.
How about Battleborn? Do you want to speak negatively about them too? They have a TEN year warranty. Full replacement for the first EIGHT years and pro rate replacement for years #9 and #10.
These lithium batteries are just TOO expensive to give inferior warranty periods like 2, 3 or 4 years. Why would anyone buy a battery with such a short warranty period???
