Great battery for the price. Has been working great for two weeks now and 800 miles no problems. Comes with the acid pack that gets dumped in and then trickle charged. If you dont have a charger it will start the bike but I would recommend going for a long ride to initially fully charge the battery on install. It will not be fully charged after adding the acid pack and riding the bike will accomplish the charge, all of these types of batteries are this way.
