I have been thinking (again) when my UPS battery died..
It's been a few years now after the battery swap.
My idea is to use a battery in a way that when ever I want , I can use what ever size I can use during that time. (due to availability of battery options here).
The method may have been used.
I need some comments on this. That is this method feasible enuf.
I will be using a standard battery, AH will be decided after calculating actual current draw.
Since a supply has 12V, 5V & 3.3V. The PG and the rest is quite easy to adapt.
The 12V will be taken directly from the battery.
The 5V & 3.3V will be stepped down by DC to DC converts.
Since High efficiency converters can be designed using latest components. This Loss will be negligible.
What do you think. The converters can be built into standard ATX PSU casing. Depending on the Power A SMPS Offline charger can be built into in too. All it needs will be heavy duty battery Connection. Battery wires will also measure on how far the battery is placed.
To keep the battery life at best, charger can be automatic. Say during power down charger charges. And if long term PC operation is needed, the charger can be used to top up the battery as the terminal voltage drops.
I like to know any draw back that this idea will produce.
