  • fridge or battery

    i have a slight problem i need some help with, my deep cycle doesnt see to be charging well off my alternator, well i think, if i charge the 2nd battery with the ctek it will run the fridge for 3 days before the error light comes on the fridge, if i disconnect the fridge for a week and the car gets drivin for about an hour a day 4 7 days 1 would thing the battery will charge a fair bit, or is the battery only as good as its first charge after it has been discharged, i plugged it in today to use the fridge and the error light came on again with the car not running, (waeco set on low voltage cutout), but as soon as i start the car up it disappears and runs fine, but if i stop the car after a 45min run the frige will run for a bit then the error light comes back on,(error light comes on when voltage is low in battery) so the owners manual says, battery is a 105amp/h deep cycle lead acid, battery isolator is a surepower and the fridge is a waeco cf60, what do ppl think, cheers samo

    Hi,

    There is a huge amount of info on this subject, see the threads on charge rate, Ranox and Redarc.

    Cheers

      battery shows 12.5volts when car is not running so if it had dropped a cell it should show a around 10ish volts 1 would think, i spend 1/2 hour checking old threads i didnt find bugger all. cheers samo

        I would go over the whole system with a multimeter first to eliminate that its charging correctly, and that your isolator has a adequate earth, turn you truck on check the voltage at the start battery should get to 14v then the isolator should open and charge the Aux at between 13.8-14.2v if you don't get a reading over 13.8v i would check the earth, then the sense wire off the isolator, voltage needs to be a minimum of 13.4ish volts to open but that just a guess cause you didn't specify the exact model you have, also a 105ah would take 8 - 10 hrs of driving to completely charge you battery

            It could still be the fridge. Some Waeco's used polyfuses for the 12v system. It would cause a large voltage drop which would cause the red error light to come on. Only if the battery was fully charged would the red light not happen.

            I had this problem and just changed the polyfuse for a better rated one. Never had the problem since.

              Hi,

              If your getting 3 days out of the battery after using a charger then the battery would appear to be ok.

              Take the car for a run and get it hot, with the engine running check the charge voltage across the
              terminals of the aux, it should be in the range 13.8 - 14.4V as aza wrote, if not then check the voltage across
              the main, if it is not in the range 13.8-14.5V you will need to check the charging system, if it is then you have
              a problem with the isolator or wiring.

              As for the dead cell, yes it is posible to get 12.5V from a battery with a faulty cell. A cell can develope
              a high internal resistance which prevents the cell charging properly, it may only charge to a small value
              ie a few amps. When you measure the open terminal voltage it will appear ok but when you place
              a reasonable load on the battery the termianl voltage will drop rapidly.

              Cheers

                Re: fridge or battery

                checked out charging system and batteries, both batteries load tested ok, isolator is ok, just a little lazy in unlinking the batteries after car is switched off, im going to replace the isolator with a continueous duty solenoid so as soon as the car starts it charges straight away not relying on the main to be charged first, also mine has been wired up so that both batteries are linked for startup only, so im putting a switch in line to allow me to any use main for starting and flick the switch if it goes flat, as for the fridge its back at waeco to get a check up and fix up. cheers samo

                    Deep Cycle takes forever to charge. Try a High Cycle you will not be sorry.

                      Hi samo, and your isolator sounds like it’s work fine.

                      Contrary to the misleading info that many of the isolator sellers state, your isolator does NOT wait till your cranking battery is fully charged before charging your auxiliary battery.

                      This advertising hype that an isolator waits till the cranking battery is fully charged before your auxiliary battery gets charged is nothing more than a myth. There are only two or three high end dual battery systems that actually monitor the cranking battery and then start charging the auxiliary battery once the cranking battery is near fully charged.

                      In your case, your isolator works the way 99% of all isolators work. The isolator monitors the voltage on it’s input and when that voltage rises above 13.2v ( because the motor has been started ) the isolator either cuts in or in some cases, the isolator may have a delay designed into it and it wait a minute or two after the voltage rose above 13.2v and then it connects the auxiliary battery to the charging system.

                      NOTE, older isolators may have a cut in voltage level as high as 13.9v

                      As to your battery, being as it’s a flooded wet cell deep cycle battery, it’s the slowest to charge so only getting about 4 hours drive time between uses, I’d say you battery is just not getting enough charging time. If your battery is discharged down to around 12v, then it can take up to 5 or 6 hours to fully charge it and if your fridge’s cut out is set lower than that, your battery needs even more driving time.

                      To be honest, it doesn’t sound like there is anything wrong with your set up other than the fact that Waeco fridges can be very finicky and thats all it is.

                        Re: fridge or battery

                        well i got a call from the fridge mob saying the main board in the fridge was buggered (new board replaced under warranty), there is no polyfuse in mine aparently, the mainboard controls the high/med/low voltage cutoff. when mine was set on medium it would cutout at 12.5 volts when its meant to cut out at 11.5 so when the car was running it wass all good, but when the voltage got below 12.5v it switched off, so i pick it up on monday lets hope its right this time. cheers samo

                          HI Drivesafe. Having similer problem to samo only fridge is ok but after running it for 4 days but probably only running the prado for 1.5 hrs per day .When I packed up on the 4th day the 2 rear AGM,S were reading 11.7 v when I arrived home they were reading 12.5 after 2hrs driving.But the calicum crank indercater light showing it needed charging.Got checked out at BATTERY WORLD all ok now but he thinks the fridge has been running off all three batteries.faulty isolator he thinks im running a 200amp ELECTRO B1-200. Then i read your post any thoughts on mine :?: CHEERS TINKERA.

                            Hi tinkera, Can't help you with the isolator, you can do some tests yourself to see if it's working, just let me know if you need help with the test.

                            Can you tell me, how long after you stopped your motor on the return trip, did you measure the batteries.

                            Cheers, drivesafe.

                              HI drivesafe. thanks for reply ,not to sure about time but was about 3/4 hr after getting home.Today rang BATT WORLD still not happy as they sold me the calicum batt.anyway told me to hook the fridge in and bring it down for testing under load it tested ok.After reading your post got me thinking my isolator switches on at 13.4v switches off at 12.6v I take it means when crank drops to 12.6v.Unless there is a itermintent fault with the isolator the front batt. should stay fully charged .BTW front batt was still reading 12.5v when I returned home on the monday but it took till thursday to show full charge in site glass.Probably about 3 hr driving.BATT. WORLD would like to sell me there MATSON 140 VSR ,these guys have been great but at the end of the day we all have a job to do.I am in two minds at the moment I hate problems in the middle of nowhere.CHEERS TINKERA.
