How deep should AGM battery be?
80%
TYPES OF AGM BATTERIES While a popular choice for deep cycling, as an AGM battery has a depth of discharge (DoD) of 80% versus a standard flooded battery which has a DoD of 50%, it is also a popular choice for starter batteries. This is because it has low internal resistance and can provide high current loads quickly.
How long will a group 31 battery last?
Group 31 batteries dimensions, features, and recommendations It provides battery capacity up to 150-250 minutes and 750-1250 CCA. The physical dimensions are as follows- 13×6 13/16x 97/16 inches.
Can I charge a deep cycle battery on AGM?
Use a deep cycle battery charger Many modern battery chargers will have a specific setting for AGM or GEL batteries. It’s essential to use this setting to charge your AGM battery correctly. The charger regulates the charging rate, ensuring that your battery can reach 100% without overcharging.
Are all Group 31 batteries the same size?
Sizing. The Group 31 designation pertains to size only and does not inherently convey any information on the power of the battery itself, although the size can dictate power generation. Group 31 batteries measure 13 inches long, 6 13/18 inch in width and 9 7/16 inch in height.
What battery type is a deep cycle battery?
lead battery
A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged.
How do I know if my deep cycle AGM battery is bad?
If the reading comes in below 10 volts, you need to let your battery recharge. After it’s charged, test the voltage and then retest several hours later. If the voltage reading drops more than a volt or two in the retest, you probably need a new battery.
How many amps are in a group 31 battery?

Do I need a special charger for an AGM battery?
AGM batteries do NOT require a special charger. However, LIKE ANY OTHER BATTERY, it will benefit from the ministrations of a quality “smart” charger. A regular ol’ constant voltage charger, such as you’d buy at the local auto parts store, feeds out power at around 12.7v (some are 12.6v, and some are 12.8v). That’s it.
Can I use a trickle charger on an AGM battery?
Many GEL, AGM and Calcium’s are better than regular lead-acid batteries but even so you should charge them back up regularly, or better still use a trickle charger (or solar panel) to keep them in top condition and extend their life. Bulk charging puts in the rated maximum current while maintinaing a constant voltage.
What does 31 mean on a battery?
What are group 31 batteries?
Heavy-duty, commercial-grade Group 31 batteries are commonly used in ambulances, firetrucks and other heavy motorized vehicles that require a long-lasting, reliable battery to start the ignition.
What is a group 31 Marine Battery?
Group 31 batteries belong to the standard commercial battery commonly used in automotive, marine, industrial applications. They’re widely popular because they are able to deliver an unmatched performance even when they are pushed to their limits.
Are all AGM batteries deep cycle?
All AGM batteries are deep cycle by the very nature of their build, however….. I recommend for RV use, it is best to use dedicated DC (deep cycle) AGM batteries that have been built with extra thick lead plates, to give even better performance and service life (8-12 years).
What is a deep cell battery?
A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity.
