Battle of the Battery Giants: Comparing Duracell vs. Battery Technology The Duracell brand is known for three of its main technologies: Quantum DuraLock Ion Core The Duracell quantum range features a high-density core power booster that packs more power than similar-sized batteries.
In comparison, Energizer batteries use: Power seal technology Recharge power plus Power Seal Technology in the Max range allows the batteries to hold power for up to 10 years. Market Dominance Duracell was the first to become a known household brand in the s and was publicly listed in Below is a table that gives an overview of both the Duracell and Energizer brands:. Size C Batteries. This battery has a NiMH chemistry nickel-metal hydride which can: Stay charged for up to 12 months when not in use Be charged up to times Last up to 5 years in storage Energizer C batteries: The Energizer brand has the Max C, which has the following characteristics: Long-lasting alkaline chemistry with a lifespan of up to 10 years at a temperature of 21 degrees celsius Hold power for up to 10 years Made with Energizer PowerSeal technology Leakage protection For secondary cells, Energizer is known for the Recharge C NiMH batteries nickel-metal hydride batteries that: Can be charged up to times Have a rated capacity of mAh at 21 degrees celsius The table below will provide a technical overview of the C type batteries manufactured by both battery giants:.

The physical size is different. Depending on how the battery and contacts seat within your devices, you may have a harder time with the Duracell Procell. The plastic is a little thicker. The Energizer has a touch more amp-hours than a Duracell Procell and many people report a longer lifespan from Energizer Industrial batteries. This does not mean they are "dead". This is voltage of the battery while it is being used. If you unplugged it, you would get a much higher voltage.
Yes, I will write a later post about this voltage drop. I hate it when I don't give a definite answer to the question "which battery should I buy? I can't help myself.
I was curious. If the better batteries have more energy, do they also have a greater mass? Let me find out. It is probably a silly idea to make a plot of just three data points, but I did it anyway. Thanks to Craig for pointing out my error. What does this mean?
I guess it means if you are worried about the total mass of your portable electronics AND you are worried about battery life - go with the Duracell or Energizer.
Oh, and these energy densities seem to be in agreement with the data posted on Wikipedia. I love that Wikipedia page on energy density. Not only is it useful, it shows you just how terrible alkaline batteries are. Alkalines have an energy density around kiloJoules per kg. Burning wood has about 16 MEGA Joules per kg yes, difficult to use all that energy unless you are trying to heat up a room or something. Oh, and look at gasoline, 47 MegaJoules per kg.
This is why we don't make battery powered cars that run on AA batteries. Help me. I can't stop. Walmart, Walgreens, KMart. The Durcell data is in blue and the Energizer is in red. I think some of the data would fit better, but there are a couple of cases where 10 batteries cost more than 14 or something like that. If I assume a linear model fits this data and it isn't a terrible fit , then the function would tell you the price for one battery. The slope tells you how much one battery would cost without the packaging - I guess you would have to bring your own box to the store.
I admit, I need more data. Although I am sort of surprised the linear function works as well as it does. It seems like you would get a discount for buying a whole bunch of batteries.
Well, in a sense you do - you only pay for the packaging the y-intercept once. One last warning. There will be more battery related posts in the future. It should be clear that I usually fly by the seat of my pants.
I pick up some cheap batteries at a store and I just assume they are alkaline. Apparently not. The dollar-store batteries I used say "heavy duty". The interwebs tell me these batteries are zinc chloride and not alkaline.
Anyway, even though they are different types of batteries, I can still compare the cost per energy. Energy The first way to look at the quality of a battery is to see how much stored energy is in it. Rhett Allain is an associate professor of physics at Southeastern Louisiana University.
