Reserve capacity rating rc is the number of minutes at 80 degrees f that the battery can deliver 25 amps until it drops below 10 5 volts.
Marine battery reserve capacity.
Testing the batteries reserve capacity discharge.
In the case of a battery like our group d27f yellowtop the reserve capacity is 140 minutes.
Definition of reserve capacity.
The sae j537 storage battery reserve capacity test states in sec 3 5 discharge the battery at 25a 0 1a.
Rc x 60 percent the two major construction types of deep cycle batteries are flooded lead acid and valve regulated lead acid.
After the batteries were conditioned fully charged and rested overnight at room temperature we started the first round of our reserve capacity discharge test.
This means that a 200ah battery can run a 10a load for 20 hours.
Technical specifications of the optima 8016 103 d34m bluetop marine battery.
If your sole reason for buying a marine battery is to start your medium power inboard or outboard engine the optima 34m bluetop marine starting battery is a trustworthy choice.
This rating is a crucial parameter to judge batteries especially deep cycle batteries.
The reserve capacity of a battery is the number of minutes for which it can run at 25 amps of current without its voltage dropping below 10 5 volts.
Significance of reserve capacity.
To figure the amp hour rating you can multiply the rc rating by 60 percent.
The reserve minute rating is the number of minutes that a battery can run a 25a load until dropping to 10 5v just like with starting batteries.
For a much smaller battery like our group d51 yellowtop the reserve capacity is just 66 minutes.
It is measured in minutes.
This deep cycle marine rv battery is rated for 500 mca marine cranking amps and 80 amp hours.
Keep in mind both of these batteries are designed for deep cycle use while batteries like our redtop line are not designed or warrantied in deep cycle applications.
Moreover the battery has a reserve capacity of 120 minutes for constant performance.
Reserve minutes also called reserve capacity is the number of minutes a fully charged battery can sustain a designated constant load usually 25 amps before it is fully discharged.
Reserve capacity is known as the amount of time a fully charged 12v battery at 80 f can supply 25 amperes at 10 5 volts until the voltage drops down.
A group 27 deep cycle battery with a rating of 180 reserve minutes will run a 25a load for three hours.
With cranking amps of 870 amperes this is a great battery for your rv or boat.
The 140 minute reserve capacity indicates the number of minutes a battery can deliver 25 amps of current without dropping below 10 5 volts.
It roughly describes the amount of energy the battery effectively stores and technically specifies the battery s charge.
