WebSome batteries capacities are rated by “Ah” or “amp hours”. Most car batteries are rated “CCA” or “cold cranking amps”. The formula works the same for either rating. Be sure that your batteries are the same rating to make sure you don’t damage one of the batteries from overcharging. Example: WebHaving obtained the two voltage readings, you can calculate the cranking amps using this formula: Cranking Amps = (Voltage Reading 1 - Voltage Reading 2) x 1000 For … WebJul 21, 2024 · “In the test for cranking amps, the BCI puts a battery in a somewhat cold environment, 32°F, and measures the discharge load in amperes that a new, fully-charged battery can deliver for 30 seconds, while still maintaining terminal voltage equal to or higher than 1.20 volts per cell. party city barbie decorations
