There are multiple tiers of batteries, I got the $50 one I linked but the first hit was $120 on their site.

So you can find the model’s battery here, and then google that and batteries plus. I have an 850M model which uses the rbc17 model. I’ve highlighted that on the apc site on this photo:

Batteries plus had a Duracell version of the one my APC unit needed, in stock in store so I could get it same day. If you’re in the US, might try them.

I think the worry of large layoffs and instability while idiots try to use AI instead of people is founded even if it’ll end in disaster.

Self insurance is also ridiculously common, so get ready to find a lot of defunct insurance when places start going bankrupt that were once seen as large entities.

Gotta keep the auditors busy!
