Better still, forget about buying the Duracell brand (which are frequently over-priced) and buy any brand of alkaline batteries from Poundland, et al. They're just as good. (Don't buy zinc chloride batteries from pound shops though, as they're almost universally rubbish).
If you want to stick with (over-priced) Duracell batteries, the 'basic' ones are labelled 'Simply', the ones which can theoretically last up to 50% longer (but rarely do) are labelled 'Plus Power' and the longest-lasting are labelled 'Ultra Power'.
'Industrial' is seemingly just a tag that they use for bulk supplies of 'basic' batteries ( http://
For ultra-low-power drain (TV remotes, computer mouse etc), you can use the super-cheap zinc-carbon types. Or rechargeables. In fact I have about 20 AA-rechargeables that we cycle in many different devices, such as radios, mice, TV remotes, even a waste-bin.
For mid-power drains (radios, torches, etc) use alkaline types.
For high power-drain (RC-controlled drones, laser pens, GPS devices) use the super-expensive lithium style batteries.
In general, batteries are the most expensive form of energy you can buy. It's a bit better to use rechargeables, from both a cost and eco-mindedness perspective, but for lowest cost, consider using a plugged-in power adapter, but switch it off when not being used.
It realy depends on what performance you want ..
