Energizer Recharge 1-Hour Charger for NiMH Rechargeable AA and AAA Batteries

I love the quick charge time with this charger, much faster than others on the market. I also works with other rechargeables

It works like a charm. One hour and the batteries are charged.

Perfect for those gamers

Oh my gosh what a money saver for those Xbox controllers that require batteries. I felt like before, I was constantly buying AA batteries. Now, I’m saving in the long run!

Lengthy Review of 1 Hour Charger + AAA and AA Rechargeable BatteriesNot sure how this will be filed as it looks like multiple products are lumped into one review bucket, and in my case purchased three items: the Energizer 1 Hour Charger along with a four pack of Energizer Recharge Plus AAAs and one of the AAs. Looked at virtually every other Name Brand option on Amazon, and seems like every single rechargeable product had reviews mentioning Not Charging or Burnt or some other Scary Thing. Picked the One Hour model as rechargeable technology is still Very Unreliable (see: Burnt) and the One Hour model allows me to plug it in nearby and Keep An Eye On It while in use. This review covers the Energizer 1 Hour Charger along with the Energizer Recharge Plus AAA and AAA batteries that were Sold By Amazon.In March 2022 the 1 Hour Charger package shipped with four of the Energizer Recharge Plus AA batteries, so with the other purchases now have the Charger plus 8 AAs and 4 AAAs - six AAs going to wireless mice with two held in reserve for recharging, and one AAA going to a wireless device with three held in reserve for recharging. What worries me is how the Charger might handle charging multiple batteries at once if one battery holds a higher charge than the others. Ex: If batteries 1-3 are at 10% and #4 is at 50%, would assume charging stops for ALL batteries when ANY battery reaches 100%. Was amazed that the heat was (at least) 120 degrees, so will be aiming a Fan at the Charger in the future.Specs:The 1 Hour Charger package from March 2022 consists of the Charger, a non-polarized detachable plug, and four Energizer Recharge Plus AA Batteries. By the date code, looks like mine was manufactured six months ago in October 2021. Charger Info would be Model#: CHR1HR3DE, Input 12-16V / 1.3A, Output 1.4V / 2.5A (for AA x 4) and Output 1.4V / 1A (for AAA x 4). The Plug would be Model#: CH1HR-ADPLUS (Intertek 9700297), Input 28W, Output 16V / 1.3A. Instructions are a tiny scrap of paper or downloadable PDF, but as others have mentioned, for some reason Energizer doesn't mention how to properly install AAA batteries in the instructions. Would think after a few years they'd have at least updated the PDF from their web site, but installation information remains AA only. Odd that they stress following their instructions to the letter, and then completely neglect AAAs. Thankfully there is information from multiple reviews - including a video - on how to properly install AAA batteries. Note: Also read online that while Alkaline batteries might be 1.5V, the standard for Rechargeables would be 1.2V.Use:Can recharge 1, 2, 3, or 4 (identical) batteries together, and refer the pictures included with the documentation for more detailed information. AAs are easy, but as others have mentioned, the Trick with AAAs is to insert them At An Angle. Possibly some of the negative reviews come from not inserting AAAs correctly due to Energizer's lack of documentation? Have charged all the AAs once and all AAAs twice, and does appear to Complete in Under An Hour. There is no On/Off switch, one merely plugs in the Charger to start and unplugs it when Done. Status is a four-bar Blue Battery Light. The Blue Battery Light is Blinking when charging, and when completely Solid would assume charging to be Done. However the Charger doesn't ever turn itself completely off, and the Blue Battery Light will remain Solid forever until you unplug the Charger. Note: Documentation says NOT to Mix With Used batteries. Strange, as as EVERY battery you attempt to recharge is by definition, a Used battery. Perhaps this is Energizer saying Product May Only Work Once? See: UP TO.Heat (VERY Hot! Use a Fan!!):The documentation doesn't mention heat, but when I pointed my temperature sensor at the Charger after 4 Energizer Recharge Plus AAs finished charging, the reading was 120 degrees!!! Can see why some people have posted pictures of Melted Chargers. Would assume from the specs that charging AAs uses more power (and generates more heat?) than charging AAAs, and perhaps charging four batteries also generates more heat than charging only two? So perhaps charging only 2 AAs might be Safer than charging four? Can see from the open design of the Charger that they are trying to have the heat from the batteries dissipate into the air, and if Energizer field-tests this product in the Antarctic, then All Is Well. Unfortunately for those of us who live in higher temperatures where water exists in liquid form, Heat Build Up is a serious concern. Started using a Fan (see picture) and the Charger temperature didn't go above 80 degrees in a room that was 75 degrees.Compared to Alkaline Batteries (60-ish%):Energizer Recharge Plus AAAs (fully charged) have about 60% of the power/time of conventional Energizer Max Alkaline AAA batteries, or to put it another way, using single AAA batteries one-after-the-other, in less time than I had used three conventional Energizer Max Alkaline batteries one-after-the-other, went through all four of the Energizer Recharge Plus AAAs. Also noticed that while one can continue to get some use from a Time To Replace Alkaline battery, when the Rechargeables get to that level, they drop like a stone and go from 40% to Paperweight in seconds. Am only using one AAA at a time, but they drain so fast that I may have to buy another four pack of AAAs for additional spares. Going to hope that after two weeks the batteries are not already losing the ability to recharge... ...they allege Hundreds of Charges, or rather UP TO Hundreds of Charges, and technically Two Charges counts as UP TO any higher number. But possibly one battery charged to 100% faster than the others, which halted the charging process?The Environment:While Environmentalists tend to turn a blind eye to inconvenient real world data to our collective peril, using Rechargeable batteries can help The Environment by reducing the number of disposable Alkaline batteries. While Rechargeables do NOT Save Energy as obviously the manufacturer can bulk produce conventional Alkalines more effectively than we can recharge batteries at home, reusable batteries means less conventional batteries to dispose of. Assuming the Rechargeable batteries do not rapidly decline in effectiveness, by recharging these AAA batteries 100 times I would theoretically have NOT disposed of 60 conventional Alkaline batteries. With luck, after two years this purchase will eventually Pay For Itself in not having to buy so many disposable batteries. Just have to hope the Quality is reliable and these batteries really do effectively recharge Hundreds of Times and not just UP TO.Trivia 1: Plan to keep some Rechargeable AA/AAAs in reserve to allow continuous use while expended batteries are recharging, so purchased a plastic AA/AAA battery case to keep the reserve batteries safe while not in use.Trivia 2: Rechargeable batteries help The Environment and (hopefully eventually?) Save Money, but one of those Pesky Details is that Rechargeable batteries only work when one has access to an active electric grid. Can't recharge batteries without power, so in the event of a power outage it makes sense to still have conventional Alkaline batteries on hand.Trivia 3: Going to guess when a single battery fails, and assuming one is recharging four-at-once, would have to try them one-at-a-time to Guess which battery is the culprit. The documentation neglects this. Would guess it would cost more to ship the battery back to Energizer than to just purchase another four-pack, which translates to No Warranty On Batteries.UPDATE: In the Q&A, one of the Answers says: -- Kindly note that Energizer 1 Hour Charger has a feature called Bad Battery Detector, which means that when a bad battery is put it will blink that way ((blinking 3 bars, then 1, over and over)) until you remove it. --AAA Battery Update: Not sure what the warranty on these AAA batteries might be, but just purchased another four AAAs (total now eight) and while the batteries purchased in March 2022 had a date code of Sep 2021, the ones purchased in May 2022 were actually Four Months Older with a date code of May 2021, so looks like Energizer rechargeable batteries - even sold/shipped from Amazon - can be at least a year old when they arrive.

Fast charging, love it

Love these batteries! I bought them for my off camera flash to avoid paying the high price tag for a rechargeable one, and it works like a charm. I saved money and the batteries last a long time. Charging is very quick as well. They usually get low to mid levels of use, but they typically charge up quicker than expected.

I’ve had this for a year now and it works great
