I like Motobatt AGM because they have dual posts for hooking up accessories.

OK thanks to all who replied. Nessism, I live in SC and was wondering what you would recommend the CCA (cold cranking Amps) would be. Also 9er Rider asked a valid question. I'm very surprised not more people answered. I have read that the AGM batteries don't have the staying power of the lead acid type. Just doing my research and any and all information is welcome. Thanks again, jon

Staying power? My 2000 ZRX came new with a Yuasa AGM. Despite never being on a maintenance charger, and being unused for nearly a year (completely dead at that point) it resurrected just fine and lasted a total of ten years. Yes, ten. The Yuasa AGM that is in it today is more than eight years old. It gets pretty regular feeding from a CTek charger, so I expect at least two more years from it.

That's what Google said about not having the cranking power of a Lead Acid battery. It must be Gospel if Google said it lmao. That's why I was looking for recommendations. I do like the idea of the multiple tabs on the Mottobat but I don't anticipate any auxiliary parts as I want it stock when I'm Done. Yuasa it is and thank you. Have a Merry Christmas and be safe.

We all know google doesn't show bias on anything, because he said that in front of congress.. Don't sweat the CCA's. If you need to worry about how long the bike will crank, you have problems other than a battery.

Now back to reality, I bought a cheap AGM battery off of ebay in oct 2016, then in the fall of 2017, it started to act like it wasn't holding a charge and starting slowly, when in actuality the bike was not charging properly due to a shorted stator and a voltage drop to my voltage regulator on the sense (brown wire).

I replaced the stator.


Added a relay to provide full battery voltage to the brown wire.


and the same AGM cheapie is still going strong. Gel cell cheapie.

Thanks for all the information. I will get an AGM battery but is there a rating or size I should be looking for. Old_kaw said not to worry about Cold Cranking Amps (CCA's) so help me out lol. They rate them by CCA's, amps per hour etc. Just want to get the right one. Again, thanks for the assistance. Jon

As far as I understand,the more CCM s the better. You need at least what the original factory battery put out but more would be better.
On the subject of Motobatt. I fitted one in my CSR project and had a bad experience with it. I was lucky to get it out in time,Im sure it was ready to burst into flames and take my bike with it. On the other hand,Ive had one fitted to my daily ride (600 Bandit) for the last 4 years and have never had a problem with it. The bike starts first time everytime (and I mean "daily" ride. rain or shine,summer, winter,gets me to work and back). The choice of terminal posts is handy but they are not easy to use if you are putting the battery in and out a lot.
