What model of battery lasts the longest? – earlier than we make a speculation that addresses this query, let’s be taught concerning the two commonest varieties of batteries.

Alkaline batteries are made with potassium hydroxide, which is a fundamental resolution (which means it may well neutralize an acid).

A non-alkaline battery is made with ammonium chloride and zinc. The ammonium chloride is acidic.

Alkaline batteries are usually costlier than their non-alkaline counterparts, identical to brand-name batteries are costlier than generics.

But in every case, what are folks actually paying for?.
