LookInto Winner in Best batteries

The best seller on the whole Electronics chart, and for once the crowd has it about right. At 39.6p a cell this is the drawer battery: clocks, remotes, the kitchen scale, the kids' toys that eat four at a time. Amazon states a 10 year shelf life, so a twenty pack bought now is not going to die in the cupboard before you get through it.

The catch: ordinary alkaline is a poor fit for high drain kit. In a camera flash or a games controller it will sag under load and you will be back in the drawer sooner than the price per cell suggests.

Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
