I've seen plenty of posts online saying you absolutely need to buy a name brand, but they always assume you're running tools all day on a job site. If you're not, that advice doesn't apply, and following it will cost you money you don't need to spend. Off-brand power tool batteries have a bad reputation that made more sense when third-party manufacturing was less reliable than it is now. You need to consider whether your situation actually calls for a name-brand battery.
