East Penn ETX9 Battery

I purchased this battery as the sellers web page indicated it would work on my motorcycle (2007 ZZR600). It does fit just fine, but the battery terminals are not the right size/shape for my wires to go on properly. I had to bend one side of each of my connectors totally flat for them to fit on this battery. No stars deducted for this as the product seems solid. Just be weary of fit and do your research.**Update**After a solid 3 years this battery will no longer hold a charge well. One winter it sat all winter with no trickle charger and took a charge just fine the following spring. This pas winter I would put the charger on it for a few days once a month or so. Just 3 months ago I started the motorcycle with no issues. But on the first nice day this year I went to start it and *click*. I put it on the charger for a few days and tried again... still *click*. Expensive battery to only last 3 years. Even if i didn't treat it well. I expected more. Maybe I shouldn't have?

I had the same experience as another user here.. the first year the battery performed well, as it should. I don't ride all the time no in my older years, about once a month. Now the battery is in its 18 month point and I found it flat after not riding for two months. I thought there was no way it would still hold charge but it does. After charging it, I left it alone for a 4 days and it still had 12.8 volts and 200 cranking amps. I think the key to this battery is keeping it charged or ride your bike more often.

First year I owned it I could leave it for over a month and it would be fine. This second year of ownership I left it for a couple months and it went flat. So...keep it maintained or get something cheaper / better warranty.
