The same battery will take about 6 hours to fully charge if the charge rate is 10 amps.
. Charging a regular car battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge it fully. Then we take the equivalent amp hours of a battery based in its RC or CCA rating see my article link above and divide it by parasitic amps. A battery charger with low amp charging such as 2 amps can recharge a battery in one to two days.
To determine the charging duration you simply have to divide the amp-hours of the battery by 10 with a 10 amp charger. This does not necessarily mean a battery will last only one hour because it will last 2 hours if its asked to produce only 50 Amps 4 hours at 25 Amps and so on. If the battery is fully empty then you just need to double these times to see the amount of time your charge will.
Sizing The Right Battery Charger The easiest way to determine the appropriate battery charger is to use 7 - 10 of the rated amp-hour capacity of your battery. Charging a car battery 4 things to remember. Free 2-Day Shipping Free Returns.
2550 hours depending on the state of the battery. Of course it will rely upon if the battery charge supports the battery itself and if theres no damage underlying the battery.
