Modern Buddy

My battery finally crapped out after a couple years of zero maintenance, so on the advice of this thread:

topic14379.html

I decided to try to upgrade my Blur YTX7A-BS to the YTX9A-BS.

Except when I bought my battery I got mixed up and thought stock was 9, so I bought a 12

It dropped right in, it's the same L and W but a lot taller. I stripped out some of the padding and left the rectangular battery cover off, the bigger snap-down panel holds it nicely in place (with a bit of padding between for vibration)

So IIRC, a 12V battery is a 12V battery and the more amp-hours the better, right?

Will my puny engine have a harder time charging it? Will it blow fuses? I expressed concern about that in the 7-to-9 Ah thread, and people said it's no problem, is it still no problem with a 12Ah?

I replaced the whimpy 3Ah battery that came in my Buddy 50 with an 8Ah battery last year and have had no problems at all.

Thanks, Jason. I reread the other thread and it pretty much confirms I'll be OK. I had just been reading about the Peukert effect and number of cells and stuff and freaked myself out. I need to stop looking at the internet.

Nah, you'll be fine. Think of it as a capacitor. Heck, let's go simpler! Think of it as a bucket with a hole in it. The hole in the bucket is the electrical drain (this gets plugged to a trickle when the bike is off) that the ignition, lighting and auxiliary/accessories drain from the battery. The bucket gets filled (at a greater rate than the drain) whenever it's running higher than idle.

What you've essentially done is gotten a larger bucket (same drain rate). When it's full, it'll just overfill. So the original battery had say 3 gallons it could store then drain before it ran out of juice. Your new battery will run out after 5 gallons of juice but it has the capacity to hold that much more potential electricity.

In terms of your battery, the overflow (what the charging system sent to the battery after it was fully charged) wasn't collected; your new battery will collect more of that before going to the overflow (waste/unused charge) and consequentially give you more or a saved charge for later use.

I hope that makes sense.

To summarize, ya dun good! (as long as it fits, lol)

i've had a 12 iun mine all season, no problems.

is that where the term 'trickle charger' came from

Same concept
