I'm an expert in chemistry but not necessarily battery chemistry, so this is an informed but, not authoritative opinion.
Conventional carbon-zinc batteries have lower stability & more heavy metals, so I tuonk there has to be a convincing & irrefutable reason for avoiding alkaline.
I haven't purchased conventional batteries in probably 40 years, so every clock we've ever had used alkaline batteries.
I would never consider changing even for low demand electronics like a vlock.
