Inverter question

Ok I bought this inverter https://www.amazon.com/gp/product/B07W5YTTTF/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

This battery https://www.amazon.com/gp/product/B00S2MCC7M/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

and my question is why does the inverter keep charging the battery up to 14.3 v then stops and lets it fall to around 13.3v then starts charging again

about 45min charging and 20 to 30 falling...

Is this normal ? is this going to hurt my battery ?

this is working as a UPS for 2 high power PC's and a laptop and satelite internet router

Any help is appreciated, thank you

That inverter says it is "modified sine-wave", you want pure sine-wave for powering any of those electronic components that rely heavily on clean power. I don't know how much it cost, but with the money of that battery, you could have gotten an actual UPS to be fair.

Actually thanks for the advice, but a power supply for a computer will have no problems with a modified sine wave. Generally you only need pure sine wave for Inductive loads like motors with brushes, medical equipment, clocks (for accurate time keeping), CFL light bulbs and Audio equipment... but that is not my question, I do appreciate the advice but I am posting here for the problem of overcharging the battery. unless that is just a float charge and will have no bearing on battery life.

I'd suggest doing some research, while a computer will work with it, it's really preferred to run true sine-wave especially with a high end PC.

It could have an impact on the life of that battery, as to how long the battery would last, I don't know as I don't have a clue on that specific battery.

13.3v to 14.3v is the typical charging range of a lead acid battery. Most car alternators, for example, are tuned to charge the battery at 14.3v.
