50g battery warning

[HP67]

Agreed. I don't like rechargeable batteries that are fixed in place although I often do use AAA or AA rechargeables. But yeah, keeping extra sets of batteries around is no problem, and Duracells are long dated nowadays and they seem tight and I have never had a leak in decades of using them. But there is still the problem of not knowing when to throw a set of batteries in the trash...
