external battery adaptation and buzzer removal to UPS

I leave the adaptation of external battery and elimination of buzzer to an uninterrupted power supply known as UPS for its acronym in English, in the observe how to adapt a battery of greater capacity for our equipment to last longer. On the other hand you can see how to eliminate the BUZZER to avoid that continuous sound when the equipment works with the battery. It is important to note that they can use car batteries, but the only detail is that they should always monitor the voltage of the same, since their voltage should not reach 11 VDC, because we could damage the battery, since these are not discharge deep, however it helps us solve in emergency moments. They can also adapt deep discharge batteries of greater capacity, the only thing that they must take into account is that the battery charging time is longer.
