firstly, u have to understand the difference between carbon zinc and alkaline batteries, those "super heavy duty" batteries u see on shelves are carbon zinc
these batteries no matter how branded they are, they will have 1/3 the capacity of an alkaline battery

so even a cheapo MR DIY alkaline battery can be 3x longer lasting than lets say branded Eveready carbon zinc super heavy duty batteries

and tests have also proven that those branded alkaline batteries are only 10 to 20% longer lasting than cheap alkaline batteries, so an energizer alkaline battery is only 20% better than lets say MR DIY alkaline batteries,
but u can get MR DIY alkaline batteries for as cheap as RM1 each battery, but energizer ones cost like almost RM4 per battery, so the cost is not worth it, its almost 4x more expensive but only 20% better

U mean charger doesn't last long?

I just bought ikea ladda. Gonna use my decade old GP charger to charge it. Hope it won't explode.

Been using rechargeable battery for few yrs now.

All this juice leaking corroded nightmare is gone. No more. And didn't buy a single battery since.
