Hello.
My name is Victor.
Today I will try to restore operation of the uninterruptible power supply for computer.
A common fault is the failure of the battery, and very quickly, within a year.
Of course I can just buy a new battery and will buy a battery every year.
But I will try to restore it because the battery just dries and you only need to add distilled
water and charge it.
I have to say that you can only recover about 30 % of all batteries, but even if I manage
to restore the battery at least half, then I will find a place where I can apply such
a battery.
Before pouring water, the battery should charge.
Small holes and convenient pour distilled water using a large syringe.
It is important not to add water lots of, only enough water was slightly visible through
the wet holes.
So, the water flooded and you can collect the battery.
Now you can insert the battery, turn on the unit and the battery is will fully charged.
So the battery is stood for 10 hours on a charge.
I tried the battery under load and the result is I did not like is the very short battery
can maintain the voltage , but it does not matter, I will be using this battery in a
different location If you think about it, the main characteristic
of the UPS should be as long work if the voltage is turned off.
Thus, to restore the UPS, I decided to connect an old car battery.
Although it is old, its capacity is superior to a new small battery
several times, so the UPS can work on it much longer.
It's a big battery inside and he's not coming, so I will join him thick wires, 4 or 6 mm
square and place it near the UPS.
For me it does not matter, as there is enough space, but I will have a good UPS.
I have a wire with a thickness of 4 mm. square.
Thus, I have found that it makes no sense to recover small batteries, it is better to
buy new or to connect the UPS with a more powerful car battery.
For me, the second option is preferable.
Well, everything is ready.
I am fully satisfied with the properties updated UPS.
Goodbye.
