![]() ![]() Magnum Display briefly flashes all battery charge LEDs, then goes blank. Auto resetting fuse, reads 3.6VDC on both sides, indicating good.Ĥ. Converter is reading 13.6VDC when pressing battery button on tank level monitor.ģ. Troubleshooting the dead batteries and facts I have so far with rv plugged into shore powerġ. A request for information to the manufacturer of the charger SHOULD get you the information. ![]() Right after plugging in you should see 14+ volts and then after a couple hours it will drop into the mid to upper 13 volt range and finally just a little lower float voltage. You can see these changes with your DVM to see if it's working correctly. ![]() That is used to de-sulfate the batteries to extent the useful life of the battery (to a point). Solar chargers have the additional Equalize charge cycle. With a solar charger the cycle repeats every sun rise. ![]() If you unplug it, the cycle above repeats when plugged in. In theory you can leave a rig plugged in without harm to the battery. When it first sees power (120V) it will go into bulk charge or boost charge for a specific time, then to Normal mode which monitors voltage, then Float charge which will hold the battery at the full charge voltage (it does not boil the battery). The GOOD controllers like the Progressive Dynamics Intelli-Power line have a charge profile. May take a while as it's tough doing ALL this work on crutches AND only able to put 50Lbs on my left foot (no more ankle) So, before I go out and buy new batteries, I'm going to test BOTH the Inverter AND the Converter. So, sounds like both the Inverter/Charger AND the Converter/Charger are connected to the batteries, but think only the Converter/Charger ACTTUALLY charges them. I read info on my Magnum Inverter/Charger that has optimized (smart) battery charging AND my RV also has Progressive Dynamics Intelli-Power 9200 power converter. I found receipt for the batteries purchased in 2017, Auto Craft from Advance Auto Parts. BTW, after replacing the 9Volt battery on my digital multi-meter, I read 3.6VDC on the two 6VDC batteries in series. 8 more weeks without full weight on my ankle (sad story) so decided to read ALL the paperwork in my DRV satchel about ALL my power equipment on board. I figure 4 will be more than enough for the minimal voltage required for the induction fan and blower, the other two will go in the camper. I'm going to buy a solar panel and charge controller and run my outdoor wood burner off of them so I don't have to worry about dragging my little generator out when the power goes TU. I happen to know the owner of Kenray and by sheer happenstance ran into him at dinner one night, a few beers and $100 later and I've got myself 6 like new 6 volt 75 amp hr batts. All usable parts got pulled and the buggy got scrapped, these batteries have been sitting on Ken's shelf for the last several months. 6 months later the customer traded the cart in on a new one because the frame was rotten. I just scored a killer deal from the vendor we use, these guys were bought right at a year ago for a customer. They aren't cheap but I got tired of all the premature failures I have gotten out of Interstate Batteries over the last several years so I'm back to running Deka in my vehicles as well. That's pretty dang good considering the usage and lack of maintenance they get. We just replaced a set that was 8 years old but only one of them had actually. they get run pretty much round the clock 7 days a week and don't get plugged in like they should. Both 6 and 8 volt batts, depending on the rig. We run Cushman industrial carts in our plant to get around (think oil refinery plant size wise). ![]()
