Possibly, but the 5Ah is typically about £60 and no guarantee that won't need to be jump started as well. Not really an issue if it does for the sake of two minutes with a couple of hits of wire. I still think this is better deal unless you need the extra capacity, which is unlikely unless your regularly using it on something like a grinder or circular saw. For DIY use I'd much rather have two of these for £75 than a single 5Ah for £60.
I know it’s new I bought one lol but it’s old discontinued stock i can’t tell the difference between the 5ah and 3ah weight wise. For those that don’t want to jump start it then be better buying the newer batteries.
These are new. It's not uncommon to have to 'jump start' new batteries. I've had to do it with other brands too.
Bought one of these the other day from store got it home was dead had to bump start it off my other battery by connecting them together. Wouldn’t say there’s a discernible difference between the 5ah and 3ah weight. Would recommend just buying a new one I needed mine same day so didn’t have the luxury.
