Ghetto hack for your UPS power system.
I have 2 UPS for pc's that I wasn't using because I have a fast switching inverter in my home but it seems in my new clinic in santo domingo, we have a diesel generator. So when the lights go off and if there are no patients in the clinic, they would take as long as 15 minutes to turn on the generator. Sometimes they wouldn't turn it on for a long time. Mean while my computer would get turned off as my laptop battery is dead. I replaced the dead battery in the ups which I had connected with my internet modem/router and laptop but it only supplied me with 10 minutes of power, max. Then within 5 months the cheap toy battery just died inside the ups.
So i started to read on the net about a hack in the ups which would give me more power and duration. remember, the UPS for computers is a small inverter and it also uses a 12 volt battery. All I had to do was replace the tiny battery inside with a bigger car battery connected on the outside. I simply took the power battery cables from inside of the ups and extended then outside of the case and connected them to a small sized car battery. Now I have a ups which will last me hours if the clinic decides not to turn on the generator. This battery will give me years of service as compared to the small tiny toy battery which came with the ups.
Here is a picture of the setup, which is not mine but I pulled it off the net. I use only one car battery.
