My Acer Nitro 5 laptop from 2018 used to deliver 6-8 hrs backup in moderate workloads for close to 2 years but in the next 6-8 months it fell by nearly half despite only 40-odd battery cycles used.
Sourcing a good quality replacement battery seems to be quite difficult. Official battery is too expensive plus I have to travel quite a bit to the nearest service center to get it done.
Can I instead use an UPS? An APC model was listed with 9V,12A battery. Assuming PF of 0.65 that's 70.2Wh compared to the original 48Wh battery.
Am I way off my mark in my calculations? If not can I at least expect it to give as long as the original battery when brand new? Portability isn't a concern as I use my laptop as more of a desktop replacement. Mostly its plugged in. But occasionally I need it run for 5-6 hours unplugged which is currently not possible as battery backup is down to 3 hours and declining further gradually.
Thanks.
