New battery for our Dyson. Should have bought one way earlier (old one was almost 4 years old). Went with the original one even though that's more expensive.
I'm still using the old one during the week as it only takes a few minutes to swap.
I've been putting this off for so long I use to be able to vacuum my entire house 2,500 sqft ish (minus furniture, etc) with battery left over. Now it dies halfway through.
I might follow you and just get a Dyson branded instead of aftermarket.
