![]() ![]() Do you want to know which are the best? Check out my post about the best AA batteries.1.5V lithium batteries are not as common as 3.0+ volts lithium batteries, but their popularity is increasing over time. The only time I’d choose heavy duty batteries is maybe in a situation where I needed the absolute cheapest battery for a short-term situation where battery life didn’t matter at all.įor most around-the-house uses, I would definitely recommend going with alkaline batteries, especially if you can find some good prices. Heavy Duty vs Alkaline: Which Should You Choose? I found that they’re not enough less expensive to make up for all of their downsides. The only potential advantage is that heavy duty batteries are sometimes less expensive than alkaline. ![]() So as you can see there’s a lot of advantages to an alkaline battery over heavy duty, but what would the advantages of a heavy duty battery be?Īctually there are no real advantages of heavy duty batteries over alkaline. Maintain a steady flow of power over their lifeĪdvantages of Heavy Duty Batteries vs Alkaline.Advantages of Alkaline Batteries vs Heavy DutyĪlkaline batteries are definitely better than heavy duty batteries in almost every way. An alkaline battery puts out almost the same amount of power throughout its entire life, making it more consistent.īecause of the fall-off in power with heavy duty batteries, they will not work in some electronic devices. The amount of power stored in each type of battery is:Ī heavy duty battery also slowly reduces its power output over time. The amount of power in an alkaline battery is about two to three times the amount of power in a heavy duty battery. Amount of Power in Heavy Duty and Alkaline Batteries If you wanted to buy batteries in bulk to have around the house, alkaline is definitely a better choice with their much longer expiration dates. ![]() Heavy duty and alkaline batteries do not have the same shelf life. The truth is that alkaline and other modern batteries are certainly more heavy-duty that heavy duty batteries! Main Battery Types: Chemical Differences They have not been the newer, better technology for a very long time, but the name “heavy duty” stuck around. Zinc chloride batteries were the newer, better technology so they were called heavy duty. You don’t see those anymore in a AA form. When zinc chloride batteries were invented, they were a newer technology compared to the older carbon-zinc batteries.Ĭarbon-zinc batteries are also called “general purpose” batteries. Why would we call zinc chloride batteries “heavy duty” when they have less power than alkaline batteries? Here’s a quick table summarize the differences between heavy duty and alkaline batteries: Heavy duty batteries are chemically different and are made of zinc chloride, while alkaline batteries contain zinc and manganese dioxide. Heavy Duty are not suitable to be used in some electronic devices and have a much shorter shelf life than alkaline. While heavy duty batteries are less expensive than alkaline, they store less than 1/2 the power of alkaline. So what’s the difference between these two? Alkaline batteries are the ones you’re most likely to see at places like Walmart and Target and your other typical stores. When you look at inexpensive batteries at places especially like the Dollar Tree, you’ll notice that some of them say “heavy duty” or “super heavy duty”. There’s actually a difference in the chemical makeup of the batteries. Well, it turns out that it’s not just a marketing term.
