Technical Talk This is a trace of both voltage and current during cranking of a four cylinder engine. The process only lasts a few seconds, but the battery voltage drops form 12.3V to 4.5V during initial cranking and is less than 10V for 2.4 seconds. And it is pretty noisy during that time. If the equipment under power cannot handle these low voltages and high noise it will crash, requiring some time to re-boot and come back on line. PowerStream's battery backups help solve this problem, whether the voltage sag is due to cranking the engine, losing the main battery through theft or accident, or battery failure. |
