What really matters is the current(amps) a battery can provide but amps remaining in a battery arent as easy to measure as the voltage of a battery. As far as those parameters making it “look like” there isnt much usable energy to be safely pulled from your battery, thats because those parameters measure just the voltage level of the battery. The advice given by this article about safe discharge parameters for AGMs and other lead acid batteries is quite accurate. If you listened to that “tech bloke” you mentioned, and have been frequently discharging your battery to 10.2 to 11.7, Id wager that youre already having issues with that battery. Have any questions about monitoring or charging deep cycle batteries? Leave a comment below. To read more about batteries in general check out this article here. When discharged to 50% and AGM battery will have around 12 volts.Ī fully charged 6 volt battery will read around 6.3 to 6.4 volts and only 6 volts when at 50% discharge.
When discharged to 50% the voltage should read around 12.35.ĪGM batteries will be around 12.8 to 13.2 volts when fully charged. Gel batteries are a little different and have a voltage of around 12.85 when fully charged. It will also be lower if there is something drawing power from the battery.ġ2.2 volts is a 50% discharge on a standard 12 volt battery.
#AGM 12 VOLT DEEP CYCLE BATTERY FULL#
This number may be lower if the battery is old and has lost its ability to hold a full charge. With no load, a fully charged 12 volt deep cycle battery should read 12.7 volts.

If you have a Lithium-ion deep-cycle battery charge it before it goes below 20% and your batteries will last for years to come. Long story short if you have any kind of lead-acid deep cycle battery then charge it when it gets to 50%. So if you camp in places that get down to freezing at night and your batteries are stored outside, make sure it warms up before trying to charge them otherwise they could get damaged. One thing to note about lithium-ion batteries for cold weather campers is you should never charge them in temperatures below 40☏. If you are planning on draining your battery to 20% over and over again getting a deep cycle Lithium-ion battery ( click to view article) is going to be the best choice. See Also: Best Deep Cycle RV Batteries (AGM, SLA, 12V, 6V)ĪGM batteries are better than gel or wet lead-acid deep-cycle batteries when it comes to discharging damage and Lithium-ion is even better than AGM. The damage when the battery goes below 50% is minimal and as long as you never let it go below 30% the battery will still be able to hold a decent amount of charge for a long time. That being said it can be very difficult to stop a battery from going below 50% especially if it’s what’s running the lights in your trailer or RV. If you want your deep cycle batteries to last for years to come with zero damage then charging them before they go below 50% discharge is the optimal way to go. Standard lead acid deep cycle batteries are made to withstand being discharged to 50% over and over again and take minimal damage. When Does a Deep Cycle Battery Need to Be Charged?
What Are The Voltages? A 12 volt battery with no load should read 12.7 volts.
