![]() ![]() Some have tried to answer this question by extensively testing many different brands of batteries. Are these LSD competitors as good as Eneloop? Though much has stayed the same since that article was written, numerous battery chargers have come and gone, and Eneloop has spawned many competitors for LSD batteries. Since then I’ve written many more articles that have been collectively viewed by over 100,000 visitors. I soon switched our family to using exclusively LSD batteries such as Eneloop, along with a good battery charger.Ī year, and a bunch of research later, I wrote my first article on LSD batteries:īest AA Batteries That You Never Heard Of Thankfully, I discovered Eneloop batteries when my son was 5 years old. Something seemed even more wrong when my rechargeable (high discharge) NiMH batteries could not power toys after 3 or 4 months despite not being used. Something just seemed wrong about buying dozens of Alkaline batteries per year to power my toddler’s toys. Toys are what inspired me to start learning about AA batteries. Despite this sizable market, Sanyo’s Eneloop breakthrough that occurred in 2005 continues to receive scant attention. consumers still spend over $4 billion annually on mundane AA and AAA batteries to power remote controls, flashlights, digital cameras (and DLSR flash attachments), book lights, toys for kids, and many other devices. There are so many headlines about breakthrough battery technologies that will be the wave of the future for autos, smart phones, or storing electricity generated by solar power. but even better because there aren’t any drawbacks other than the higher up-front cost. Well, low self-discharge (LSD) batteries are the cast-iron skillet of the battery world. When to Use Alkaline or Lithium Batteries (hint: rarely)ĭo you own a cast iron skillet? If so, how often have you had to replace it? If you treat it well, the answer is never.Extra Features to Look for in Premium Chargers.Recommended LSD Battery Brands (and Country of Choice: Japan).The LSD trade-off: Higher capacity means fewer recharges.Why LSD Batteries Blow Away the Competition.I also provide a Just Tell Me What to Buy section for those who just want to cut to the chase. I recommend specific products for different budgets and needs. When Jim’s testing reveals new information, appropriate changes will be made to this guide.Īs you can see from the following table of contents, I cover LSD batteries, budget chargers, premium chargers, storage, and other AAA and AA-battery-related topics. Jim has been supplied with a few chargers to test by DC Workshop. In addition to this guide written by me, Jim Hyman will continue to test batteries and write articles for FilterJoe. ![]() The technology and products associated with AA batteries and charges change slowly, so this will be easy. It will be maintained and updated to stay current through early 2019. This guide is a 2017-2018 update on AA and AAA rechargeable batteries and chargers. If you prefer to understand what you’re buying, read on. If you prefer to skip the details, click to the Just Tell Me What to Buy section of this article. Once you’ve tried LSD batteries with a good charger and realize how good they are, you’ll end up using them for the vast majority of devices that require AA or AAA batteries. When used with a quality charger, LSD batteries offer the best combination of long-term cost-effectiveness, quality, durability, and environmental sustainability. Use pre-charged, low self-discharge (LSD) batteries for AA and AAA battery needs. But if you want to use these in electronics that are on for long periods or use a lot of power, like a set of string lights or a video game controller, you may need to recharge these batteries frequently.After 6 years of researching and writing about AA and AAA rechargeable batteries and chargers, this site continues to have the same basic advice: Opus charger performing a different function on each LSD battery: 400 mA charge, 200mA discharge, internal resistance test, charge test That’s quite a bit of time for devices used infrequently or with minimal power, like TV remotes or flashlights. If you aren’t using them immediately, they can maintain a storage charge for up to a year.Įach charge gives these batteries 5.5 to 8 hours of use. These batteries are pre-charged and ready to use right out of the package and can be recharged about 1,000 times in their lifecycle, potentially replacing hundreds of single-use batteries.Įnergizer’s “Extended Life Composition” also promises up to five years of regular use before they need to be recycled. They’re also made from 4% recycled batteries, making them more environmentally friendly. This set of eight AA batteries from Energizer is an excellent household pack for keeping remotes, cameras, and kids’ toys up and running year-round. Runs down somewhat quickly between charges ![]()
