I have an older robot vacuum that has finally shown some age in its battery. The charger will charge for about 15 mins and then gets an error, but it’s enough to do a decent vacuuming of the room if I charge then vacuum, then repeat once more. I can’t leave it on the charger now due to the error repeating, so basically I run it dead until the next time.
So my question is, can I continue doing this since it works well enough, or is there potential problems/danger with the battery being at less capacity? I could buy a new battery, they aren’t terrible in price, but if it works and is safe, why not continue what I’m doing until it completely gives out?
I did that for like a year until I broke down and bought a replacement battery. Weird thing was that it didn’t act like it had lost any capacity. Still took the usual amount of time to charge and cleaned for about 30 minutes on the high setting.
Would just let it charge until it started error-beeping, pull it off the charger, and then turn it off with the physical switch until I needed it again (if I didn’t do that, it would periodically wake up, crawl back on the charger, and then start beeping lol).
Kind of defeated the convenience purpose of it, but it was still good for cleaning under the furniture and such. I just had to make sure it was off the charger before I went to bed or else it would beep all night.
