I've been keeping track of the health of the OEM battery, a blue-label Motolite Gold.



Back when it was new last April 2024, I took a reading with the batt. analyzer and it gave me this:


Then this month (October 2024):


So far after approx. 6 months, the battery CCA has gone down 3.6% while the internal resistance increased around the same percentage (3.5%). At this rate, this should last more than a year, at least.

I have been putting it on a battery maintainer on weekends to top it off and this practice proved to be very helpful in the past on prolonging the battery life of my previous vehicle.
