any suggestions for a new battery for my f4? thanks!

 

I'd try out the Motobatt. I just got one and I like it so far. Reviews have been good, and it has connections for accessories (if you like that)
Best part is it's a sealed AGM for $60 delivered. Kinda hard to beat that....

red top batteries are by far the best, but not cheap, other than that, you get what u pay for

 

I've seen bad reviews on red tops, too... just like every other battery. But do they even make a moto red top??

To say it's the best or that you always "get what you pay for" with anything else is complete BS. There are a ton of great manufacturers making AGM batteries for less.
I'll never spend $200 on a battery, but if it makes you happy... by all means.

Also, here is a review on the motobatt if anyone is interested. I thought it was an interesting read....
I'm willing to give the motobatt a shot.

 

I can't afford to spend that on a battery, I actually just got a $60 dry cell battery from wallmart, it will work just fine, red tops are like battery bling...lol My grandfather bought me one for my buell when i was younger, and that thing lasted forever, but i have never had a problem with any battery, they all do there job

 

motobattery on ebay, cheap with great quality
