- And the Tesla fuckery continues. Since moving into our place in August, I had noticed that our six year old Powerwall has been very vastly underperforming against its 13.5 kWh capacity. LOL go fuck yourself Tesla. I will not be accepting two-thirds of a battery from you.Feb 3, 2026 06:57
- Is it a powerwall2? I believe they are getting replaced under a product recall. I saw something about them being capped in the meantime
- Nah. It is a Powerwall 2, but I don't think that this is to do with that. The apps are showing it going from 10-100% on well under 9 kWh consistently since we took ownership in August. Loads of PW2s manufactured around 2018-19 have degraded extremely badly: www.netzero.energy/content/2025...
- That’s very odd. Their cars haven’t degraded that much and a car has a much harder life with rapid charging and hard acceleration. I assume it’s the same cells.
