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’ve never seen a dead battery that didn’t eventually go full “spicy pillow,” but until then they’re as safe as new (assuming no physical damage to the battery). That being said, it wouldn’t hurt you to take it to a certified battery recycler and get a new one.
Good point. It looks fine so far, but apparently not only overcharging (which I think isn’t a problem since the charger seems to detects current flow) but deep discharging could lead to this. So my running it down until it stops could eventually get things unstable. And it’s enclosed so I’d have to literally remove the cover regularly to make sure it’s okay. I guess that was what I was looking for, something that might be a problem down the road. Thanks.
