Advice on a battery beard trimmer?

I've had my beard trimmer for years. I've replaced the battery once already. It was welded in (talk about planned obsolescence) and I had to make due with soldering an off the shelf AAA. The motor and such are fine, but the battery is going again. I'll end up fixing it, but I don't wanna rely on it. This is a real PITA.

Anyone know of a battery beard trimmer that has a replaceable battery?
