PSC 15 / D7500 float charge question.

Recommended Posts

I charged my new D7500 (sitting for a bit but never used) from 12.6 last weekend. The initial float charge was 13.1, but rose to 13.4 by day's end. Over the last week it has slowly risen to 13.8 while still in float mode. Is this something to be concerned about? The manual says is should be floating at 13.56 volts. My garage is about 65 - 70 degrees right now.

Here are some exciting pictures of the voltage progression...
