UPS and battery compatibility

[Vince47]

I don't know what the rest of you think about it, but how about a versatile motorcycle battery like this (?): https://fr.vidaxl.ch/e/8019887384976/ba ... jQQAvD_BwE

Description
5 year standard battery with high AGM technique.

Here is the battery I plan to use;

To see the characteristics of this battery, simply download the catalog on this page (DOWNLOAD CATALOG), then page 4, last line of the table, it is the battery with code H74

It's still a car battery!

My personal feeling is as follows, it is better to have a fully adapted battery - therefore one that is intended to work in an inverter with optimized ad hoc cycles - because otherwise, the lifespan may be affected (with potentially other problems that I do not know) and the device must be brought into compliance. I don't know what the comrades of the forum and I could be wrong. But to avoid any mistakes, I would ask Écus Ondulique for advice and compare their prices.

When you see the inexpensive price of replacement UPS batteries ...

It is a starter battery, not the best suited for this type of use. No info on the number of charge-discharge cycles https://www.myshop-solaire.com/quelles- ... a_238.html

A classic car battery is designed to deliver significant power for a few seconds, it will not withstand the deep discharge cycles that the inverter will require for a long time. If it is to troubleshoot with a car battery that is lying around why not, but even if it means buying one, you might as well take a suitable battery. The ideal would be a gel or AGM.

Then what will be the use? If it is to use it as a computer inverter, you might as well take the same battery as the original one, it will take up less space. If you plan to increase the autonomy, as indicated by Macro, you have to see if the inverter is able to operate for longer. I dismantled a small inverter where the power transistors were fixed on the solid blocks of aluminum, without fins. They were therefore mass cooled, necessarily for a limited time.

One of the things I find interesting about using a car battery is that it happens quite often that my car's battery drains because I leave it parked without starting it for too long.
I have a PC under an inverter anyway, so instead of this inverter charging its standard small battery, it will charge a spare car battery (which I already have).
So when the time comes when the car is discharged, I will only have to use the battery that charged on my inverter.

[Obamot]

Too long is how much? 1 month? months ? How? I get the idea, but ... Isn't that a sign that it's time to change that car battery?

And then the reasoning works both ways. An inverter battery is certainly not made (nor powerful enough) to start an engine.

[GuyGadeboisTheBack]

What I understood is that he is using his inverter as a battery charger. After all why not ?

[Petrus]

OK, so the UPS will be used to maintain a charged backup battery, and is not intended to drain this battery to keep the equipment powered. So I don't see a PB, you just don't have to rely on the larger capacity of the battery to let the inverter run longer than with its original battery.

Last winter it also happened to me that the battery of my car did not have enough juice to start after 2 weeks at a standstill, but it has still been working since.

Otherwise there is this:

Who is a “real charger” of car battery, who will charge it with care and who is not a “battery killer”!

For 18 roros ... but where is the problem?
