If it ain't broke...

Are the charging systems the same on both bikes? If yes, I'd buy the bigger battery next time.

A friend needs a new battery and i noticed the DL1K battery is 12amp where the DL650 battery is 10amp. The DL1K battery is also a little taller (5-3/4 vs 5-1/8 for Wee). Will the DL1K battery fit in a 650?

Im a bit puzzled why they made them different. Thoughts?

Looks like it's only a few dollars more for the extra 2 amps. Is it worth it?

The higher capacity battery is about 5/8 of an inch taller. It will fit.

I bought an AGM version for $39 from Amazon a few months ago. Free shipping with Amazon Prime. Brand is UPG, which is a major battery supplier.

Bigger motor takes more juice to turn over.
30,000 miles, 4.5 years and the stock battery has been fine for me, so I don't really see a need, but it certainly wouldn't hurt anything.
