Review: Se é pra comprar pilhas, compre uma vez na vida. E essa linha eneloop é o que tem de melhor e mais barato a longo prazo. Review: I'm a big fan of Eneloop batteries. The long shelf life doesn't just translate to usable batteries after a long time lying around, but also a longer battery life in general. I had several packs of Duracell which wouldn't hold a charge after 5 - 6 years of mixed storage and light use in remote controls; They saw maybe three to four dozen discharge cycles at most. Meanwhile some Eneloop AAs I bought back in College for my camera flash and mic are still going strong, and they are around twice that age. This pack of AAAs was sold by 'MYBATTERYSUPPLIER', and you should always check who is selling them before you buy. In this case the listed quantity of batteries was correct, manufacturing date was reasonably recent (2 yrs ago on mine), and I used an online guide to verify the authenticity of the batteries. Most of the negative reviews you see on desertcart are people saying they got fakes, so just make sure you check the seller's sign-up-date and ratings, and you should be fine. One final word of wisdom, mAh is used as a marketing term. It's tempting to get the highest value you can find, but there can be a few flaws to that logic. Firstly, manufacturers may use different testing methods, as well as cell qualities. While I'd feel confident getting X mAh from a known brand like Duracell or Energizer, it's common for cheap batteries to list inflated values. The second thing to consider is self discharge rate. Not only are low self discharge batteries likely to 'live' longer, but a standard NiMH battery can lose up to around a quarter of it's maximum charge in the first 24h after charging, just sitting around. So unless you are charging that shiny 2500+ mAh battery and draining it immediately, you can actually be getting less capacity than a low-self-discharge cell. This is less of an issue with know brands, but unless you use the battery soon after charging, you will still get less capacity than you might expect. ## Features - LONG LASTING PERFORMANCE: Recharge eneloop AAA rechargeable batteries up to 2100 times - POWERFUL NiMH RECHARGEABLE BATTERIES: eneloop AAA Ni-MH pre-charged rechargeable battery deliver up to 850mAh typical, 800mAh minimum - PRE-CHARGED AND READY TO USE: eneloop AAA rechargeable batteries are pre-charged at the factory using solar power and maintain up to 70% of their charge after 10 years (when not it use) - SECURE, PROTECTIVE PACKAGING: This package contains 8 eneloop AAA rechargeable batteries - EXTREME TEMPERATURES: eneloop rechargeable batteries can used in extreme temperatures, down to -4 degrees Fahrenheit - QUALITY YOU CAN TRUST: These eneloop rechargeable AAA batteries are made in Japan and packaged in the United States - HUNDREDS OF HOUSEHOLD DEVICES: Perfect for use in hundreds of household devices, these eneloop AAA rechargeable batteries can be used in remote controls, flashlights, toys, wireless computer devices, rc cars, digital camera flash units, game controllers and more ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JHKSMIG | | Amperage | 1.2 Amps | | Antenna Location | Camera, Toys, TV Remote, Gaming Controller, Radio, Flashlight, Mouse, Remote Control Vehicle, Wireless Keyboard, Phone | | Battery Capacity | 800 Milliamp Hours | | Battery Cell Type | NiMH | | Battery Weight | 13 Grams | | Best Sellers Rank | #51,752 in Electronics ( See Top 100 in Electronics ) #423 in Rechargeable Household Batteries | | Brand | Eneloop | | Built-In Media | Panasonic BK-4MCCA8BA eneloop AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack | | Compatible Phone Models | flashlight | | Customer Reviews | 4.8 4.8 out of 5 stars (11,730) | | Global Trade Identification Number | 00073096902046 | | Item Dimensions | 21 x 86 x 108 millimeters | | Item Type Name | Panasonic BK-4MCCA8BA eneloop AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack | | Item Weight | 4.08 Grams | | Manufacturer | Panasonic | | Model Name | FBA_BK-4MCCA8BA | | Model Number | BK-4MCCA8BA | | Number of Batteries | 4 AA batteries required. | | Reusability | Rechargeable | | UPC | 600682784238 073096902046 | | Unit Count | 8 Count | | Voltage | 1.2 Volts | | Warranty Description | Eneloop pre-charged aaa nimh batteries-8 pack | ## Product Details - **Battery capacity:** 800 Milliamp Hours - **Battery cell composition:** NiMH - **Brand:** Eneloop - **Number of batteries:** 4 AA batteries required. ## Images ![Panasonic BK-4MCCA8BA AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack - Image 1](https://m.media-amazon.com/images/I/71nU3O-DXbL.jpg) ## Questions & Answers **Q: How long does it take to fully charge these aa batteries with my eastshine s2 charger?** A: The charger claims it will charge them in 2 hours, right on the product description page. Maths tell us the S2 fast charger charges @1A per hour and the batteries hold 2A. Protip, if you start answering a question with, "I don't know, but..." or, "I don't own one, but..." you have failed and most people ignore the rest of whatever you wrote. **Q: Green Eneloop on NC-MQN06U charger, blinks green a couple of times then stops, no light. Battery charged no more than 100 times. Are they dead?** A: Recommendations for eneloops and any rechargeable batteries. 1. Buy a good charger. 2. Don't quick charge, the extra heat will shorten the batteries life. 3. Replace them when they are low, don't leave them draining with the power on in devices. You will have two or three that won't charge without a paper clip jump (earlier post) . 4. Don't mix dead and charged batteries, the drained will be charged by the full ones the worst way to charge a battery.5. Dont mix newer generations of eneloops and older generations-it goes back to newer eneloops charging the older batteries. 6. Buy a good charger that monitors each battery throughout the charge! Yes, I said it twice. **Q: can these batteries be used with cordless phones** A: Yes. That's what I am using them for and the packet specifically mentions dect cordless phones. These batteries are almost identical to the original batteries that come with cordless phones that come with rechargeable AAA bateries except that these batteries have a much larger capacity (800mAh) letting them last longer between charges. **Q: Do these batteries work on Panasonic cordless phone model KX-TG93 series?** A: If the original batteries were NiMh then yes. If they were a different chemistry, such as nicad then it's not a good idea. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***A on 20 December 2025* Se é pra comprar pilhas, compre uma vez na vida.
