The fastest form of charging is by [[electrical:12v:alternator|alternator]]; if you have alternator charging start the vehicle and take it for a drive. | The fastest form of charging is by [[electrical:12v:alternator|alternator]]; if you have alternator charging start the vehicle and take it for a drive. \\ |
| Note: if using [[electrical:12v:alternator#isolators|a plain isolator]] a completely dead aux battery can pull enough current to cause resets or overheating. Use other methods first then use the alternator when Vbatt comes up a bit. |

Solar, if present, will often be a gentler charging method. MPPT will run normally but PWM charge controllers will be [[electrical:solar:pwm_tweaking#pwm_s_achilles_heel|especially weak when battery voltage is lowest]]. | Solar, if present, will often be a gentler charging method.
