Is this a big battery?


Before you get too excited, the sticky tape on the batter is to keep the label on, not to clamp it. lol

I'm pretty sure all my accessories are running off it - everything except mains. It doesn't take long for my 95lt fridge fault light to come on because of low battery?

Do I need to upgrade?

[Ben-e-boy]

you need to show us a pic of the amp/hour rating (A/h). A/h will tell you how many amps it can draw in one hour before going flat. ie if its 90 A/h it will go flat in an hour if its drawing 90 amps. 670 cold crank amps (CCA) is pretty big you can go bigger. I have a 750CCA in mine

About 300 long and 200 wide looking at that pic. lol sorry was just a left open question

I guess it was a DAQ, but that's about as much as I know about batteries. lol

It's about 29cm long x 18 cm wide. It looks about the same size as my starter.

If I have to pull it apart to look, but I'll hear what you have to say.

Batteries can be damaged if regularly taken below 50% of their capacity, so that 90 hours becomes 45 hours if you want to maintain a good service life of your battery.

Ive got a 120AH deep cycle and my waeco draws about 2 amps when its running, so it will drain my battery to 50% in 30 hours. But due to the thermostat, its only running about 50% of the time so that 30 hours then becomes 60 hours safe run time, lost of variables in this so could easily be half on a hot day getting opened all the time and warm refills (mmm beer)

Deep cycles are much better suited to running accessories and will handle being drained better than a cranking battery, if it is stuffed id be getting a deep cycle.

30 hrs, you're a legend! lol

I'm lucky to get a couple. Looks like another expense in the near future. Thanks

parked up with out the solar hooked up 80amh battery iget about 18hrs run time

Those ratings (CCA and RC) would seem to indicate it's a starting battery not a deep cycle. Deep cycles are rated in A/H (amp hours).
Deep cycles are better suited to running accessories.

X2 with Tony, Roscoe.

Thats a Cranker hence the CCA rating. I'm tipping it will be an 85 AH or thereabouts

It won't be the best choice trying to run that big Evercool of yours. The only reliable way to find the State of Charge (SOC) is by measuring the resting voltage but if you are only getting a few hours I'd say the battery is definitely a bit sad.

With the Evercool you would ideally want a 120AH AGM (Absorbed Glass Matt). AGM's will recharge quicker and can be safely drawn down to a much lower SOC than a standard wet but are exxy.

However... the fault light will still come on at the same value even tho the AGM can handle it better. Check your user manual for the frig. The Waeco's etc come with a switch that you can use to set the Fault Light to different voltages to suit different battery technologies.

Ross, I am not totally up with batteries, but I think an intermediate product is a deep cycle marine battery. Can get big CCA's and also have advantage of more amp/h. The batery itself is more robust for off roading while suiting lower discharging.

Go here and ask these guys as they are also 4WDing family all set up.
