Calendar Event: Voltage and status lights Posted: 29 Apr 2018 at 8:37pm |
After 10 days of being left alone/at rest, my 178 HRE with two DC24 marine batteries showed 3 lights of 4 lit on the interior status display. Checking the voltage with an ohm meter, I found 12.04v. I check that with depth of discharge tables and that shows ~ 45% left, 55% discharged. My battery charger showed a similar reading of being at 40% charge remaining.
I tend to believe I am more than 50% discharged, yet the idiot status lights show a more positive reading. Does anyone know what voltage, or discharge rates are represented by the 4 lights in the HRE?

those lights, no matter which item they are checking, are hokum. They are feel good lights for people who really don't need them. If you are serious about your battery usage, and health, get and install a good monitor system.

The only part of that 4 light thingy that is worth looking at is the one for the fresh water. And even it isn't all that reliable.

I added an outlet that has a LED volt gauge, cig lighter plug and 2 USB ports, I needed the 12v and USB capabilities.

Agreed! Those status lights are definitely useless.

I put in the same thing as Mike a few weeks ago and it works great. It gives a pretty accurate reading on battery voltage. Amazon has them. Worked great for phone charging on our last trip.

Same here. I need to add a pushbutton so that the voltmeter isn't on all the time.

Here's the one we got from Amazon. It has a switch to turn it off and on at the upper right. Under the little rubber flaps are the plug ins for usb and 12v.
