Can I Charge A Deep Cycle Battery With A Car. As a general rule of thumb the heavier the deep cycle battery the thicker the lead plates the longer it will last. Charging the deep cycle batteries with the battery chargers is the proper way of charging such batteries unless they are connected to the electric system of a car truck RV boat etc.
10 amps are needed for Deep Cycle Marine Batteries. But in real-life situations deep cycle batteries may be recharged in many ways and some of them are not ideal but they may help. Also if you deep cycle a deep cycle battery automotive alternators are not really good at quicklyfull charging a deep cycle battery.
Save the process for an emergency otherwise it really is best to use a charger that is specifically meant for your marine battery.
Answer 1 of 9. The basic car battery is a 48 amp battery so it would take a 24 hour period of charging at 2 amps for the battery to receive a complete charge. To understand the way your alternator works is more important. The voltage regulator in the alternator or connected nearby maintains the voltage at about 145 V which allows the downstream charge to a 12V system However there has to be a sufficient dr.
