I'm looking for a SLA battery for the CRE mz201 engine. It's 626cc with 9.1:1 compression and has a 450 watt starter motor. Given the 450w starter motor size, what AH battery would be large enough, 5AH, 7AH, 9AH?
Who has some favorite battery links? Batteries you just bought and are happy with?

P.S. I've seen all the Lithium suggestions... Please SLA suggestions only here. Thx!

Hi Phil,
I just ordered a new SLA battery on Monday for my GEO engine. The previous battery (lead/acid) I had got too old
to hold a charge, so it was time for a new one. I'm trying to wrap up a few small projects, so that I can start the engine real soon.
Regarding size; I didn't want to go any bigger than necessary, but I also didn't want some puny SLA that wasn't up for the task.
I ended up getting the same size as I had before, only this time I went SLA, rather than usual lead acid motorcycle battery.
From looking up lot of "cc" motorcycles, I would suggest an 7/8 AH as a minimum for a 600cc range engine, but a 9 AH may be
a better choice.
One like this;
http://www.ebay.com/itm/12V-9AH-Sealed-Lead-Acid-SLA-Replacement-Battery-/270922243286?pt=US_Batteries&hash=item3f14395cd6#ht_1433wt_1063
Of course, if someone has direct experience, maybe you could get by on a 7 AH, but I would think that that would be the absolute smallest
you'd want to consider! (A quick search on eBay looking for 600-650cc motorcycle's batteries turned up 9AH batteries, FYI)

I'd like to comment on this, and I hope I can do it w/o offending...
Only you know fer shure the battery condition and history (abuse or not,
etc) but from just the words you used I am guessing that a desulfator would
have added years to the life of the battery.
I'm not sure how many people are aware of these things. They are not that
rejuvenator stuff you pour into your battery. They are not quack stuff from
some dark corner. MANY companies produce them, I noticed when I last
replaced my RV power supply that many of them from big-name firms offer an
onboard desulfator circuit. They work. They are cost effective as they last
for years and can treat any number of batteries. I have used them for years.
They don't work on worn out or damaged batteries. But in sports like
motorcycling, off-road stuff, aircraft... it is perfect.
A LA battery that is left to sit in less than full charge state will grow
sulfate crystals on the surface of the plates. In WWII the submarines used
a.. (what the devil did they call it?) Think equalizing charge. It was
simply a higher voltage, higher amperage charge to top off with. It did two
things- it topped off with a full charge, plus it burned off any sulfate
that might have been building up. The sulfate is... you guys don't need alla
this do you? Just ask me if you want any details...
I just think a $25 desulfator will save you money. It does me.
