New Battery for 850 T3

[tonyduc]

All
The battery I have used for the past 3 seasons always was a bit weak for cranking power but now it’s in decline. It’s a Yuasa YB16hlacx rated at 20ah(20hr) and 240A(CCA). I’ve seen posted elsewhere here that Cali owners have had luck with Odyssey's PC680. This would fit my T3, the 925 is a tight fit.
Haynes says the battery should be 32 A. Just curious what is the rating specification that matters, 20 hrs or CCA ? The specs for Odyssey pc 680 says 170 CCA, but Cali owners seem happy with it.

BTW, as far as charging the voltage at the battery terminals is 13.9 - 14.2 @ 2,000 rpm, so it seems my alternator is good.
Thanks
Tony

This is what I have in all 3 of mine, been lasting 12yrs          12V 34AH AGM U1 group some have been a UPS batt for computer back-up or sun storage. No issues ever and cost $100 or better. Only one is Chinese & doing well. I get them at Batt + store

Odyssey 925 is a drop in fit on my stock T3. It's 15 years old and still works excellently. I like the big battery because everyone uses my charging ports at the campsites.

Few years back I had problems with the Bosch starter going intermittent. I replaced it with the Valeo from EME. It works so much better than the Bosch ever did. The gear reduction lowers cranking amps while maintaining cranking speed. It's also a bit lighter.

Between the Odyssey and the Valeo the T3 comes to life no matter what the weather.

Have always just used the standard lawn and garden battery to can buy about anywhere.

Repaired enough acid damage on frames and fenders to never consider a "lawnmower" battery.

Hmmm. Could see that I guess just never had an issue. Owned the bike since 89.

Or at least use a "sealed/maintenance free" lawnmower battery.

For my budget conscious customers, I use this one: https://www.amazon.com/gp/product/B00B9JD7PG

Thanks all, I ordered an Interstate 35 AH AGM battery on Amazon for under $100. 35 AH should solve the slow crank issue. At least on my T3 don’t know how I’d squeeze a typical lawn mower battery in there.
