Have you ever wondered what does RC mean on a battery? If you’re into remote-controlled vehicles, you might have come across this term before.<\/p>\n\n\n\n
RC stands for “Reserve Capacity”, which is the amount of time a battery can sustain a minimum load of 25 amperes before its voltage drops below 10.5 volts. This measurement is crucial for applications that require a reliable power source for a prolonged period.<\/p>\n\n\n\n
When you see 160 RC on a battery, it means that the battery can sustain a minimum load of 25 amperes for 160 minutes before its voltage drops below 10.5 volts. This measurement is usually found on deep cycle batteries, which are commonly used in boats and RVs.<\/p>\n\n\n\n
If you see 140 RC on a battery, it means that the battery can sustain a minimum load of 25 amperes for 140 minutes before its voltage drops below 10.5 volts. This measurement is often found on automotive batteries, which are designed to provide a burst of power to start the engine.<\/p>\n\n\n\n
MCA stands for “Marine Cranking Amps<\/a>“, which is the amount of current a battery can deliver for 30 seconds at 32\u00b0F (0\u00b0C) before its voltage drops below 7.2 volts. This measurement is commonly found on marine<\/a> batteries, which are designed to start boat engines.<\/p>\n\n\n\n RC, on the other hand, stands for “Reserve Capacity”, as explained earlier. Both MCA<\/a> and RC are important measurements for marine batteries, as they need to be able to provide a burst of power to start the engine and a sustained power source for onboard electronics.<\/p>\n\n\n\nWhat is a good battery reserve capacity?<\/h2>\n\n\n\n
