Reserve capacity.
Reserve capacity (RC) – helps to power your vehicle’s electrical system if the alternator fails. It identifies how many minutes the battery can supply ample power without falling below the minimum voltage needed to run your vehicle.

What does 160 RC mean on a battery?
Reserve Capacity
RC: Reserve Capacity is a very important battery rating. This is the number of minutes a fully charged battery at 80°F will discharge under a 25 amp load until the battery drops below 10.5 volts. AH: An Amp/Hour is a rating usually found on deep cycle batteries and is a capacity rating.
What does 140 RC mean on a battery?
Reserve Capacity
RC is a general indicator of how long a new, fully charged battery can continue to operate essential accessories if the vehicle’s alternator fails.
What does MCA and RC mean on a battery?
This rating is also called marine cranking amps (MCA) . Hot cranking amps (HCA) is seldom used any longer but is measured at 80 ° F. Reserve Capacity (RC) is a very important rating. This is the number of minutes a fully charged battery at 80 ° F will discharge 25 amps until the battery drops below 10.5 volts.
What is a good reserve capacity in battery?
25 amps
Battery reserve capacity can help you decide whether a battery is useable. It should be able to reach at least 25 amps before the voltage drops. Anything less than this is usually a low-quality battery.
How long does RC battery last?
RC car batteries will last for about one to two hours before they should be recharged. However, RC batteries should last for up to three to six months. RC batteries die fast because the engines of the RC cars are constantly powering the batteries at high speed.
What does 90 RC mean on a battery?
Reserve capacity
Reserve capacity (RC) – helps to power your vehicle’s electrical system if the alternator fails. It identifies how many minutes the battery can supply ample power without falling below the minimum voltage needed to run your vehicle.
Is RC the same as amp hours?
Reserve capacity rating is more realistic than amp-hour as a measurement of rating. For example, let’s that a battery have 160 minutes reserve capacity at 25 amps. A common understanding is that, if we draw the current at 50 amp, the battery will last for 80 minutes.
What does RC min 25 amp mean?
reserve capacity
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. For a 12-volt battery, that means battery voltage will have fallen to 10.5 volts.
How long will a 12V 12ah battery last?
approximately 120 hours
The watts/volts are equal to the amps per hour. A tiny device such as led lighting of power 1.2 watts running on a 12volt power source will use 1.2W/12V = 0.1 amps. Therefore, a 12ah (amp-hour) battery will last for approximately 120 hours.
What does 750 MCA mean on a battery?
marine cranking ampere
The marine cranking ampere (MCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 32 F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery.
What is 1000 MCA on a battery?
Marine Cranking Amps
– CA (Cranking Amps) or MCA (Marine Cranking Amps): the maximum current that a new, fully charged, 12V battery can deliver for 30 seconds, with the voltage NOT dropping below 7.2V at 32°F (0°C).
What are RC in a Marine?
It is sometimes referred to as Marine Cranking Amps or Cranking Amps. RC Reserve Capacity. Reserve Capacity, (RC) This rating is the number of minutes a battery at 80 degrees F can be discharged at 25 amps and maintain a voltage of 10.5 volts for a 12 volt battery.
What should a fully charged 6 cell automotive battery indicate?
What should a fully-charged 6 cell automotive battery indicate? Explanation: A fully-charged 6 cell automotive battery indicates 12.6 V and a specific gravity of 1.29 at 32℃. There should be no leak.
What is CCA and RC in car battery?
Purkeys’ Sales and Service Engineers Rylar Masco and Charley Gipe explain how a battery’s Cold Cranking Amps (CCA) and Reserve Capacity (RC) values can be used to determine what kind of battery is needed for a particular application.
What does MCA mean on a battery?
marine cranking amps
CCA is the cold cranking amp rating which tells you how many amps will be delivered to the engine in cold temperatures. MCA or marine cranking amps is conceptually the same rating, however, the CCA rating is based on amps delivered at 0℉ and the MCA rating is done at 32℉.
Can you overcharge a RC battery?
One of the most common ways that LiPo batteries are abused is in how people overcharge their batteries. If users leave their batteries charged for too long, the batteries can become damaged, performance can be lost, and the life span of the batteries can decrease.
How can you tell if an RC battery is bad?
Puffing or swelling shows that the battery is damaged, and therefore you should discontinue discharging or charging immediately. Further, swollen cells have a higher IR; thus, you should stop using the entire pack immediately. Damaged LiPo batteries get puffy, and releases smoke when charging.
Is AGM battery better?
How much value do you put on your time? Having established that AGM batteries typically perform better, offer more safety features and last longer than flooded lead-acid batteries, we will concede that there are some instances where flooded batteries are a better option.
How do I know if my battery is AGM?
Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out. On the other hand, the liquid acid batteries have a removable top which is not the case with AGM batteries as they are properly sealed.
What should a 12-volt battery read when fully charged?
about 12.6 to 12.8 volts
A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
