My Dyson V15 battery has started to die really quickly—I'm barely getting 5-10 minutes out of a full charge, even on Eco mode. I’ve had the vacuum for a little over two years, so I’m guessing the battery has just worn out from regular use. Before I go ahead and order a new one, I wanted to get some advice from others who’ve already replaced theirs:

Did you go with the official Dyson V15 battery or a third-party option?

Are there any reliable aftermarket brands that actually last?

Any issues with fit, compatibility, or safety?
