Hello sir/maam, is it recommended to unplug your a/c when the battery is already full?
Does it harm my battery when i forget to unplug my a/c though my battery is fully charged? Actually im using a 5253-BZ656 Acer notebook.
granted the battery will slowly degrade, but it's a better choice than letting it repeatedly drain power and re-charge it repeatedly. personal experience; my one year old laptop used to be able to handle 6 hours with the battery. nowadays, it'll go for 5.5-5.75 hours.
if you're crazy extra serious about prolonging the battery's lifespan, then there's keeping it in an airtight bag and putting it in the fridge
