Hello. Is it possible to Ippon Back Power Pro 500/600 connect AGM-battery (traction, non-road) capacity 100Ач (designed for inverter). Want to get a switch that would switch the power source from internal battery to external, and the port that would allow you to connect an external big battery. Do I understand correctly, the characteristics of the UPS (battery) is determined solely by the capacity of the battery? On this basis, it is calculated what the average time for a home computer (3-5 minutes.) and displays load, which can be connected to the UPS has provided the estimated time (I'm a little on the other hand, of course, that first stated characteristics of the load, and the battery is chosen for her.). The internal charger is designed for charging it of installed capacity. From this we can conclude that to connect an external battery pack nedostroen. Ready two feet lies a charger for the AGM. Ie, I connect the charged battery to the UPS, and after a power outage and output a battery charge I charge it manually.
Do I understand everything?
And do I need to connect the battery via diode to give, but didn't take charge from charger UPS? Can such a scheme to damage the charger of the UPS?
And allow the connection through the diode do not remove the battery from the UPS when it is charged or the diode does not affect it?
Can the external battery pack to provide a large amount of Autonomous operation at nominal 500/600Ва? And is it possible to connect, for example, 1000W, namely whether it is safe for the UPS?

Yeah, maybe.
Do I understand correctly, the characteristics of the UPS (battery) is determined solely by the capacity of the battery?
No, wrong. The battery life also depends on the connected load. With a small load on the UPS will last not for minutes and hours and more.

Decisive here is the original purpose of the UPS. The most part familiar to us UPS is designed to give the user time to save work in progress. Conventionally, it is believed that 3...5 minutes it is enough, and that the conditional average computer monitor consumes no more than 500 watts. From here, you select the capacity.
With the power of this UPS issue is more complex. These same 500 watt is the power that it can provide for most of these 3...5 minutes. If you connect a battery with a larger capacity, then the user may consider extend this and make a mistake, because on a full-time capacity for a period exceeding the standard, the inverter UPS is a decent warm up. This is evident even in their small size transformer and radiators key, if you take it apart and see.
That's why the author of the previous answer and wrote that I would need forced cooling, which is not in the original design. And I will add that it should be powerful enough. This will be the necessary alteration.
internal charger designed for charging that is installed capacity. From this we can conclude that to connect an external battery pack nedostroen.
Not quite. It is considered that the maximum battery life is achieved by charging-up current of 0.1 C. the charge lasts 14...15 hours. If you connect a battery with a larger capacity, the charging time will increase from 15 hours in proportion to capacity. Other nuances there.
However, if you agree to charge manually, you can use any other charging mode (including a fast charging mode high current for gel working. frustrating), but for the health of the battery then will not answer the regular charger, and you.
do I need to connect the battery through the diode...Can such a scheme to damage the charger of the UPS?
It is highly desirable diode is not put because it you will lose a substantial part of the energy of the battery, due to voltage drop on it. Even if it is a Schottky diode with a drop of 0.2 volts, at a current of 20...30 amps (which is typical the discharge current of the battery in the UPS) to the diode will dissipate a 4...6 a watt, and it will require the radiator. And as with conventional silicon - and all the watts 15.
Damage to the charger when you connect a bigger battery is not going to happen - he will have to work longer, but it is designed for long-term work.
is it possible to connect, for example, 1000W, namely whether it is safe for the UPS?
You can't do that. Even at normal power for longer work you will need additional cooling, and while most likely trigger overload protection or (if not) the smoke will appear. For more power it is better to buy a more powerful UPS.

1) you can Connect any lead of the battery, including AGM
2) Inside the charger for a fixed current, e.g. 5A. Battery 17 Ah will charge about 3.5 hours, and 100 Ah for 20 hours - it should be taken into account. It is also worth noting that the battery in a charge mode will say "thank you" in the form of increased life time.
3) to Increase the capacity above the nominal or UPS at best will go into current protection or temperature, and at worst - burn

can be mounted
the battery is fully charged but slower
for longer work/minor capacity increase will have to add forced cooling

Well, Yes, the UPS can be safely used such https://aky.com.ua/category/gelevye-akkumuljatory/ gel battery as I do now, in fact. As it say above, the capacitance is too big is not necessary - so to complete your work and turn off the device. And longer, then it is you need backup power system that with gel batteries is impractical.
