Eneloops are high quality
Eneloops are pretty much the go to for rechargeable batteries. These Panasonic batteries have proven themselves for a long time annd their popularity shows. They work great for all kinds of devices, especially for high drain electronics. Good long charge and always works great after multiple uses.

14 years later still holds the charge
I bought the Eneloop batteries back in December of 2011 when they wer produced by SANYO and then another pack in 2018 produced by Panasonic. They are truly the best in the game. As of June 2025 they all still hold the charge just like new even though Sanyo have been working for 14 years and Panasonic for 7 years. I bought Energizer around the same time and they do not hold the charge at all, lasted only 5 years. I will keep buying them as long as they are being produced.

Greener, Cheaper and more Reliable than Alkaline Batteries
These Eneloop NickelMetalHydride rechargeable AA and AAA batteries outperformed Alkalines in every category!1. Capacity of the Eneloop AA's is about 2X more than Alkalines (1900 mAhr for Eneloop AA's).2. Self-Discharge Life is better (several years).3. Can discharge at higher currents with less voltage drop: Under moderate to heavy load the voltage of the Eneloop is similar to 1.5V Alkalines (~1.3V for both). Voltage discharge curve is flatter than Alkalines (Alkalines discharge to well below 1.0V where most appliances stop functioning leaving 40% loss of total capacity). My experience is that most applications requiring AA or AAA batteries will work fine with the NiMH1.25V 'lower' voltage rating.4. Lower cost per use: Since they can be recharged hundreds of times, higher purchase cost is easily offset by much lower cost during the life of battery.5. Eneloop's are more reliable and do not leak! Alkaline batteries leak; particularly when deep discharged. The corrosive Alkaline electrolyte destroys the appliance contacts and circuit boards. Eneloop batteries also have Alkaline Electrolyte but do not leak (based upon experience with hundreds of batteries). Capacity of the Eneloop’s degrades slowly over hundreds of charge cycles.Use Advice:1. Don't drop the batteries! A drop to a hard surface may damage the battery internally with no obvious signs of exterior damage. A damaged battery may have lower capacity or may not hold a charge.2. Use the Panasonic 4Cell Charger! (BQ-CC17 Individual Cell Charger): Do not use series-cell chargers. For example, appliances which use 4 cells in series such as RadioControl Transmitters can charge the cells while still installed. Charging in series can damage batteries as cells inevitably become miss-matched resulting in overcharging damage. An alternative is a good single cell NickelMetalHydride Charger such as “Miboxer C4-12 Universal Smart Rechargeable Battery Charger Intelligent 4 Slot Output”.3. Allow the battery to cool to room temperature before charging or use.

AI Chatbot Recommend
Both Gemini and Chatgtp recommended these rechargeable batteries for my Tecsun AM/FM/Shortwave radio. Arrived fully charged. My radio's circuitry quickly recognized the battery technology and switched to rechargeable mode. Long lasting even with daily use.

Winner and still champion: high price but good long term value
I have been buying rechargeable batteries since the late 70s. I'll tell you some things. Get a high quality charger.(I am using a 15 year old maha C 401fs. It now costs $44. A cheap charger will beat up your batteries and make your investment worthless. Look for individually controlled charging slots, - delta-v, temperature monitoring. I like to charge AA and AAA batteries at 500 ma. Slow charging means your batteries take more charging cycles.I see a "top review" that alleges these are "fraud batteries" because unused they drop to 1.3 volts. the opinion expressed in that review should carry little weight. It's important to remember that NIMH batteries might be chargeable to 1.5 volts but that is just "surface charge" and it will disappear with the smallest use or time. NIMH technology is rated at 1.2 volts. When you take a battery off charge and measure it immediately the voltage you are picking up the "surface charge" effect; that is the reason you can ever get a 1.5 volt measurement off nimh batteries but that's just "Surface charge" it does not represent useable power. Don't believe me? Then it's time to learn more about battery charging. I'd suggest your favorite search engine.If you use rechargeables the way I do you will spend a lot more than $4. a year on batteries so a good quality charger makes sense. 1. Candlepower forums does not sell batteries or chargers, but the folks there publish the best reviews, including technical details. 2. Eneloops whites are simply the longest lasting batteries available. Low self discharge (aka pre-charged nimh, aka LSD batteries should hold an 85% charge through a year of storage in reasonable conditions and these do. I have used them all from Eneloops to tenergy centuras to the old (no longer available) Harbor freight precharged to duracell precharged. I am lucky if any other brand takes half as many charges as eneloops. I use a 4 AAA moderately high discharge flashlight about 10 hours a week for work and that's a couple of charge cycles. Also my Oral B, and a grooming appliance are powered by AA's, along with the usual complement of low drainitems where I might use a lesser NIMH battery. I do think the price is high, but I buy white eneloops for high-use systems because they last. The black eneloops store more power but do self-discharge a bit more, and do not take as many cycles. Bottom line: bite the bullet on price, go quality and enjoy reliable, economical, low environmental burden batteries; Japanese eneloop whites are the best of breed.

Great product for Mice
Best batteries on the market.I use it on Mice mostly but is suitable for any product that takes rechargeable AA.
