The Square trade warranty offered on Ebay's page is based on top seller performances. As sellers, we are not affiliated with square trade, receive no funds from it, and have no control in removing it. That is solely the discretion of Ebay and Square trade.
Battery life depends on various factors. Keeping the batteries under charged over a long period of time or leaving them undercharged will reduce the battery life. Also if the batteries are over discharged (below 10.5V for a 12V battery) it will reduce the life. Your equipment should have a low voltage protection. Otherwise manually, you need to watch the voltage.
