Electronics » Time for a new battery.

Went to Pennsylvania for the weekend. No issues, but coming back after 3 solid days on the bike, I stopped to use the facilities and decided to bleed off the tire pressure (topped off before starting). It was 36 F when I added air, so the sensors showed way higher pressure. Blead both down to 1 psi over my norm. This took only a couple minutes, so I powered on the bike and did the deed. When I got back on, the dash was already throwing me a low voltage warning. This should not have happened after a couple of minutes, but cold shows the weakness of a battery, so I think it's safe to say it's on its way out.

Went with Big Crank ETX14. My last Big Crank lasted over a decade, and came highly recommended.

Interestingly I was thinking of fitting a voltage monitor to the bike to give an early warning of problems.
But while out the other day I noticed the NAV actually gives you a constant reading of the voltage.
Only had it a year🤔😉

... the Nav V and the R1200RS display are both a voyage of discovery! You can also select the voltage (and many other non obvious items) to be displayed in the bike display.

Well, new battery has been in for a week and some change. I took the stock battery to be load tested, and it passed. However....

My Innovv system has a light that is on when there is sufficient power to operate (cuts off to save the battery). Stock battery would keep this light on for a couple of days. The new battery still has the light going even though I’ve not started the bike once since installation.

Granted, the Big Crank is 220 CCA (stock was 200 CCA), but both batteries are rated at 12 Ah. I suppose the extra CCA makes the difference...or the OEM battery is just of mediocre quality.
