I replaced the stock #7 battery in my 09 KLX250S with a Ballistic Evo2 battery. The stock battery was about 6lbs. and the Ballistic battery weighs in at .8lbs. SO for a $99.95 I got rid of 5lbs. of dead weight and have a kick *** battery with 135 cold cranking amps. If you try and duplicate that weight reduction with titanium....it would cost about $400-$500 in hardware.

Needless to say I'm now a dealer for Ballistic battery's.

Just my 2 cents.

 

I won't take my perfectly good battery out of the bike to lose the weight, but I will be looking at the Evo2 option when its time for the battery to be replaced.

 

I could take a dump and get rid of five lbs...LOL

 

Nice.. Good alternative

I see this one on Amazon for $89.. Or they have the same one, but in 80 CCA for $43.

What is the stock CCA? The $43 one may be a decent replacement as well.

 

I remember commenting on the Ballistic batteries a few months ago. CPR, give us a long term test update, if you would. If they hold their charge as many years as the trusty old lead/acid jobs, I might be interested. I think the battery in my 9 is going on 6 years. I don't remove it from the bike....I just ride all year.

 

The stock CCA i believe is around 90 to 95. I wouldn't go any less than that. The Evo2 that's in my bike is a 4 cell like the one on Amazon for $89. 135 CCA.

 

Zomby has been using one of these for a while and has good reports...

Kicks ***. I have the bigger one in my car, and it starts it (12-1 compression 16V 4 cylinder) in -10C weather.

 

I dropped 30lbs. off my ZX14 last year by eating less.

 

How does that work? Any write/ups about it?
