You can discharge it until it won't even light a few LEDs, but you'll shorten the life of the battery dramatically. It's a good rule of thumb with AGMs that you should not discharge them to
less than about 12.2v
which is about 1/2 the rated capacity.
Is it bad to discharge AGM batteries?
| State of Charge 12 Volt Battery Volts per Cell | 0% 10.5 1.75 |
|---|
Can AGM battery be fully discharged?
In time, AGM batteries (including OPTIMA batteries) may fail. Failures usually happen when a starting battery is used in a deep cycling application. In many cases, AGM batteries that seem to be bad are perfectly fine.
They are just deeply discharged
.
How low can you run a AGM deep cycle battery?
The truth is that any lead acid battery, be it a Gel Cell, AGM or flooded batteries such as DCBs, should be cut-off
at 11.6 volts
. Not doing so increases the risk of damage to the battery and if taken down deep enough into the batteries charge, will ruin the battery.
What is depth of discharge AGM?
It is generally accepted that the most economic and practical depth of discharge (DOD) for an AGM battery is
50%
. For Lithium-iron-phosphate (LiFePO4 or LFP) which is the safest of the mainstream Li-ion battery types, 80% DOD is used.
What should a 12 volt AGM battery read when fully charged?
Measure and record: A fully charged standard AGM battery should have an output voltage of
approximately 13 volts
, just higher than the 12 volts likely to be labeled on the side of the battery. If the reading comes in below 10 volts, you need to let your battery recharge.
At what voltage is an AGM battery dead?
They're rated down to an end point of 10.5 volts. By then, lights get dim and TV picture small. A Specific Gravity of about 1.200 or a voltage of 12.25 to 12.3 means the battery is about 50% discharged. By the time it's down to
11.8 or 12 volts
, it's almost dead.
Can I use repair mode on AGM battery?
Yes
. AGM batteries are a type of lead-acid battery, and Repair Mode can be used on them. … Please note that the battery should be disconnected from the vehicle or application before Repair Mode is used on it.
What voltage is 50% of an AGM battery?
| SOC(State of Charge) AGM Battery Voltage | 60% 12.05V | 50% 11.95V | 40% 11.75V | 20% 11.35V |

How do I know if my deep cycle AGM battery is bad?
Measure and record: A fully charged standard AGM battery should have an
output voltage of approximately 13 volts
, just higher than the 12 volts likely to be labeled on the side of the battery. If the reading comes in below 10 volts, you need to let your battery recharge.
How far can you discharge a 12v AGM battery?
You can discharge it until it won't even light a few LEDs, but you'll shorten the life of the battery dramatically. It's a good rule of thumb with AGMs that you should not discharge them to
less than about 12.2v
which is about 1/2 the rated capacity.
Is a lithium battery better than a AGM battery?
Lifespan: All batteries degrade over time, but
lithium-ion batteries consistently outlast AGM
. Factors like a larger depth of discharge make lithium-ion batteries more resilient and help these batteries go up to six times the life cycles of AGM alternatives.
How long do AGM batteries last?
If kept in a charged state when unused, the common lifespan of a 12-volt Gel or AGM battery is
up to six years
. After five or six years of float voltage
What voltage is too low for a 12 volt AGM battery?
The truth is that any lead acid battery, be it a Gel Cell, AGM or flooded batteries such as DCBs, should be cut-off at
11.6 volts
. Not doing so increases the risk of damage to the battery and if taken down deep enough into the batteries charge, will ruin the battery.
How many volts should a fully charged AGM battery have?
AGM batteries will be around
12.8 volts
when fully charged. When discharged to 50% and AGM battery will have around 12 volts. A fully charged 6 volt battery will read around 6.3 to 6.4 volts and only 6 volts when at 50% discharge. To read more about batteries in general check out this article here.
Can you trickle charge an AGM battery?
Severely discharging and leaving the battery discharged can cause harm and shorten life in AGM batteries. … If you're not going to use the battery for a week or more at a time, we highly recommend
a charger maintainer
(also called a trickle charger) to keep the battery from discharging.
