New battery

Thursday, Jul 9 2020 [5,273 miles]

My battery was fine. However, there have been a few reports from 790 owners of early, sudden battery death. Add in a 25% off sale on Antigravity Lithium batteries with restart. The result is a new (much lighter) battery for my 790.

The battery arrived yesterday. I put it on the (lithium specific) charger over night. I do that will all new batteries. Today I’ll put it in the bike.

I pulled off the saddle, the portion of the body that covers the battery (two screws), and the retaining strap (one screw). Power (and battery charger pigtail) leads were removed, ground first.

The side-by-side shows the stock battery to be a bit taller. Plastic feet come with the Antigravity battery to make then the same size. I snapped them onto the bottom of the case – that was a mistake – installed the battery and re-attached power leads.

The stock battery has a cut-out between the plus and minus terminals. The retaining strap sits in this cut-out. The replacement battery does not have the cut-out, making the strap sit too high. I disconnected and pulled the battery to remove the feet I’d snapped in earlier.

Much better. After buttoning up the bike I turned on the ignition and reset the time and date. The bike is ready to ride.
