Yep. I'm still very happy with it. After 4.5 years it is by far the longest lasting motorcycle battery I've ever owned. By comparison, AGMs lasted about 2 years and conventional lead/acid batteries last 3 years. This is primarily due to the heat here in the desert. The MMG lithium ion on my CB1100 has proven to be unaffected by the summer heat. I have needed to use the cold weather warm up procedure a few times, but sub freezing starts are pretty rare around here.
I recently had an AGM battery die on the old CB750 after just over 2 years (with the usual sudden death failure mode). I considered replacing it with a lithium ion like the one I'm using on the CB1100, but decided against it. The older bike's charging system tends to vary quite a bit over the usual rpm range, while the CB11's charge rate is rock steady from idle to 5K rpm. Most of the problems I've heard about with lithium ion motorcycle batteries have been on older bikes with less stable charging systems. So, for the older CB I decided to go back to the tried and true conventional lead/acid battery. The reduced life and sudden failure mode of the AGM just doesn't work for me, and I'm not willing to risk a lithium ion with the antiquated wobbly charging system.
