Depends on your location (USA, Australia, UK, Timbuktu et al)
Some members can relate disaster stories for the same brand that others have had success with - and a lot of that is "date related". One generation of a single brand is rarely equal to the next generation, and Lithium batteries are improving and becoming cheaper each year
All I can suggest, is that you choose a brand that has a high turnover (reduces the risk of “old stock”), and from a company that has a fixed guarantee
Not perhaps the answer you were looking for, but at the moment Lithium is a crap shoot as to what you will end up with
I have two new Lithium’s at the moment, but as they’re a recent acquisition, I have no idea of what’s six months down the line …..
