I would check the connections. it's summer time that the corrosion really builds up there. get a battery terminal cleaning brush, it's like 1.99 at the auto parts store and try cleaning the battery terminals and all the connection. DONT BREATHE close to this when doing so. I would do this first before replacing anything as it can affect not only battery power, but charging of it as well. either way you will need one of these too. I've helped 4 friends out with "dead batteries" this summer and it was just the contacts.
