…at least when they’re not exploding.
We bought a new living room couch several years ago, seating three, with the rightmost seat an electrical recliner with a battery-powered motor. (We could have plugged it into the floor if there were outlets in the floor here. There aren’t.) Carol and I have not used the recliner feature much. When we want to recline, we typically lie down on our bed. But whether the recliner feature was actually used or not, the battery would discharge every few weeks to the point where it wouldn’t move the seat. A week or two ago, I pulled out the battery to charge it up via the charger that came with the couch, and…I saw what you see above.
Note well that I did not unscrew or pry the case open. What you see above is exactly what I saw when I pulled the damned thing out from under the couch.
The battery consists of seven flat lithium cells in a stack, with a charger board on one side. The cells all inflated like cushions until the pressure of their expansion popped the plastic case.
When electronics die, I often pry them open to see what’s inside. Not this time. I exiled the pack to our patio just as I found it, and set it atop a thick travertine slab just in case things got…hot.
Our local Batteries & Bulbs store (where we have occasionally recycled dead 18650 lithium cells) won’t take it. So now, with a possible firebomb sitting on a fat tile on our patio, I have to scan around and find somebody who will take it. So far, nothing. I’ll add a coda to a future Odd Lots when we finally get the damned thing out of our hair. And no, we are not going to buy a replacement battery pack for the couch.
