Why are you asking? Do you have your owner's manual?
Any place that sells batteries can look up one to fit, it is a very common size, and yes, they do fail frequently if the vehicle is used primarily as a soccer-mom vehicle. A trickle charger will double the life of your battery, but does require one to connect and disconnect it (and on a Honda you can't use the one that plugs into the cigarette lighter as that is dead with the key out).
