Where Does the Electricity in an RV Come From?

[VonDakota]

An RV has an internal battery that can be charged. Here is some relevant information about the battery: Battery: A battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. The battery referred to here is a lead-acid battery, which is primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. The normal lifespan of a car battery ranges from 1 to 8 years, depending largely on the vehicle's usage. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. If using a multimeter, measure the battery voltage when starting the engine. You can first use a high-frequency discharger or a battery tester to measure it. Under a load current of no less than 110 amps, the minimum voltage should not be lower than 9.6 volts and should remain stable for 5 seconds. If the voltage is below 9.6 volts but remains stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable within 5 seconds, dropping rapidly to 0 volts or close to 0 volts, it indicates a potential battery failure, and replacement may be necessary.
