However, the second battery cannot be directly connected in parallel with the original car battery. The stalling use of electricity may cause the original car battery to lose power and it is difficult to start the vehicle. On the other hand, the line load is too heavy when the two batteries charging together. Therefore, a battery isolator is required. HOW TO WORKS The battery isolator, also known as a split charge relay, uses your vehicle's power to charge an auxiliary battery and blocks your starting battery from getting drained by your equipment when the engine is turned off. The auxiliary battery isolator will only allow the extra battery to charge at whatever rate the alternator can manage.
