I use zooms 200ah and liked it so much that I ordered another. Here are key details to ur question though. Where to buy from I think is key from my personal experience just YESTERDAY. 1st purchase of zooms 200ah was Amazon 2 years ago. Next purchase was Walmart online. Same exact battery. This is what was sent through a third party through Walmart online. It had box cutter marks on the top, serial number tag was removed, packaging was well u can see for your self. Again this was from Walmart online purchase personal experience. The1st zooms I got has done well but this one got sent back.
