Are the different brands of batteries that different?

Question

I see batteries at the convenience store from all kinds of different brands and the prices are quite different, but I can't see any obvious difference. Is there one?

Answer 1

Yes duracell are head and shoulders best. Then energizer and rayovac. The rest are all a crapshoot.

Answer 2

of the store verity to price difference is national brand name verses store name. example CVS alkaline AAA batteries verses Everyready alkaline AAA verses Duracell alkaline AAA . Duracell has better ingredients then the others and CVS would be cheapest based on bulk purchases. Also estimated shelf life would be higher in a premium battery. I use rechargeable batteries. Initial investment is more cause I have to buy the charger and a set of batteries at the same time, Average cost for everything is around $20. but they last for years and years.

Answer 3

i have a wireless mouse that takes 2, AA batteries.
i used Energizer for a while with no problems,
i bought some Rayovacs that were less expensive
and i swear to god they are smaller.
It takes some shaking of the mouse to connect and even then they do not work 100% of the time.

Answer 4

dollar store brands and/or thirft shop batteries tend to have less nickel in them. there was a customer report out of them in nbc news a few months ago. they have no guarantee on them, they might mess up your electronics and then you will have to get new electronics (if you can afford that).
best thing is get brand names like energizer, duratel. good names. they guarantee their batteries.
for a few more dollars i rather get something that will make my electronics work and not damage them and then me having to spend more moeny for no reason.

Answer 5

The cheap ones can really suck if they sat on the shelf forever. I'd go with rechargables, look for some good NiMH and compare mAhr ratings. Get two sets so you can always charge the dead ones while you use the good ones. They last 1000s of cycles.

Answer 6

the checmical makeup of the battery as well as construction. cheaper batteries sometimes use cheaper constructions and are more prone to things like leakage and explosion.
