Hi, thanks for your video. My deep cycle battery load tests in the high yellow area. My question is if I charge it with a battery charger, will it always stay in the yellow no matter how long I charge it? Thanks
Isn't 12.3 Volt equivalent to a 50%discharge? And a fully charged marine deep cycle battery is around 12.7volt? Or am I getting something completely wrong?
I use the multimeter and load tester, but a great tip and refresher. I do have a question regarding the Load Tester "Charging System" section at the far right of the scale. I noticed that both my trolling motor batteries register in the left Red section indication weak. The Load puts the needle in the 12 volt range where it's usable. My cranking battery which is a year old indicating Green in the Charging System area. So why does my needle move to the Charging area on the scale?
Are you checking the cranking battery while the outboard is running? The charging area is used to check for the higher voltage. This voltage is present when the alternator is charging the battery. If it's doing so when the outboard is not running, my next step would be to put a multimeter onto the battery to see where it is sitting at voltage wise.
@@TheWeekendAngler my outboard is not running. The multimeter measures at 12.67 to 13. Maybe because I have the onboard charger plugged in yet power to it is off there is some residual charge. Thanks or your reply.
@@alanaho4915 that is a little strange, but not out of the question. The capacitors in a charger can hold a bit of a residual charge. Your voltages look good, so you shouldn't have to worry about damaging anything.
@@TheWeekendAngler the vehicle battery the needle does not go to the Charging System section. Only during the engine running. So I guess I'm good for now. Thanks

The best most informative video on testing batteries I have seen. Thank you!!
Thanks, exactly the information i was looking for!!

So if one or the other reading is low the battery should be replace regardless.. Is that what you're saying? Video is a bit confusing.
There are two areas on the meter. A good battery should be in the green when resting and be in the other green during the load test.
@@TheWeekendAngler That I understand its the multimeter reading that's questionable saying it not charge enough.. The battery is like 50% charge
Great video. Thank you 👍

yes 12.4 is considered deeply discharged, 12.7+ is fully charged
@@k24_4twentyok thanks for the reply. So the battery that he considers fully charged is actually almost dead. That is poor advice in this video...

Awesome tip 🤠
good tip josh
great tip
Great tip Josh !
What if the marine battery has MCA instead of CCA?
Basically they're the same thing. The only difference is CCA is measured at 0 degrees F and mca is measured at 32f.
