Which alkaline battery lasts the longest

The slow charging of a car battery is best. A fast charge makes it less durable and may even damage the battery. Normally a rate of 4 amps, like the first charger I mentioned, is a good charge rate for all types of car batteries. The belief is that the chemical processes involved in rapidly charging a battery can lead it to degrade faster than regular charges, reducing range.

Do batteries expire if not used? Are there other ways to test alkaline battery life in product devices? Yes there are , but they are not as accurate and produce highly irregular results. If you choose to do your own testing at home, they must be controlled by running several different devices and many many test repetitions in order to make positive statistical battery comparisons.

This can be very time consuming and expensive. These tests should also be done with intermittent use cycles to be valid such as turning the device on for one hour per day, like the ANSI tests. Without sufficient testing, the data is usually misleading. We recommend that you always use target devices such as toys, cameras, and flashlights and use multiple devices of the same model at least 3.

A key issue with testing batteries in this fashion, is that across different brands and models of devices. This type of testing also requires several repetitions of tests of each battery brand in each battery operated device. What are the continuous use alkaline battery test?

The continuous use alkaline battery test continuous drain test or constant battery burn test is when you switch on a device and leave it on to compete exhaustion.

Batteries should never be tested in devices under continuous power drain. This is not a way that a majority of consumers use batteries.

Most alkaline batteries are not designed for continuous high power drain use, such as a high wattage LED light. Most batteries are formulated for pulsed power and many daily use periods which is most consistent with regular consumer usage.

So, product device testing should always include intermittent drain test schedules in cycles. The test is: Which alkaline battery lasts the longest out of the different bran names of Rayovac, Duracell, Energizer, and Eveready? We predict that the Duracell brand will last the longest because of their advertising claims that no other alkaline battery can beat the copper top. We tested each of the new flashlights by using two test batteries. We then tape labeled each regular flashlight with the battery type brand name and put the different batteries types in each of the marked flashlights.

Before starting the test we will turn on each flashlight at the same time. Them we left them on overnight. We logged the time that we turned the flashlights to the on position. We watched the flashlights until they went out and record the time period.

When one flashlight goes out before the other, we insert two more of the same battery types and just waited. Our experiment results quickly showed that the Rayovac Brand of Alkaline Batteries outlasted all of the other batteries. The Eveready brand battery lasted only 6 hours and 35 minutes and the Duracell brand lasted 15 hours. The Energizer brand lasted 22 hours and 15 minutes total. The Eveready brand flashlight light went out very quickly and had to replace the batteries quite often.

We also observed that when the Eveready brand was going dead it went dim very slowly. Fri p. Fri a. Sat p. Fri Went out p. Sat Total Time Turned On 15 hours 22 hours 15 minutes 6 hours 35 minutes 24 hours 30 minutes. Our hypothesis was absolutely wrong tae Duracell last the longest.

We suggest to purchase Rayovac over all other brand of batteries. How to Make a Dry Ice Bubble. Egg in Vinegar Experiment. How to Make a Popsicle Stick Catapult. How to Build a Toothpick Bridge. Milk and Food Coloring. Water Bottle Rocket.
