Review: TL:DR - Best Batteries for Game Controllers and long term recharging - These are seriously amazing I have tried many different Ni-MH rechargeable batteries and these are the best! I use batteries a lot for 2 reasons My Camera Flashes and my Xbox Controllers and there are the go to for their long life have easily already saved me twice as much as i paid for them from not buying standard batteries . Ni-MH Batteries i have tried Energizer 2300mah Gen 2 Ni-MH Rechargeable Batteries - HORRIBLE and worthless - should be criminal on how fast these things drain if you don't use the batteries within 2 weeks they are already down to half a charge if they sit around. Energizer 2100/2200mAH Gen 3 Ni-MH Rechargeable Batteries (Green box with Mah at top of battery ) - DRASTIC improvement over the other ones these hold a charge much better with only a small drain over time. Their life cycle seems to start to decay a bit after about 50 - 60 recharges Duracell Ni-MH 2450 Mah Rechargeable bought at Costo - The biggest capacity of all the others and indeed they did last a bit longer for about the first 10 charging cycles and hold their charge for months without apparent lose. But even at Costo these were a bit price I bought them before I saw desertcart had a 2400 Mah Model . But too expensive since the desertcart Basics are about the same quality desertcart Basics 2400MAH (black batter Green leaf on it Generation) - My #2 choice after about 20 charge cycles these are still exactly as advertised and in High Drain devices like my Camera Flashes these actually last longer then all other batteries but oddly take almost twice the amount of time to charge for just a small uptick but if you have a high drain equipment these are the gold standard. I actually think the have more capacity then they are rated for to be honest. And with the recent Price drop (I paid nearly 50% more then they currently sell for as a Oct 2015) These might be the new go to. These are as good as Duracell if not Better for half the price! But my preference is still my current Gen Eneloop (white ones here) - They Charge Fast - I have seen almost ZERO capacity drop off in over 100 charging cycles on these. They charge holds for months with almost no loss. They are still my go to over desertcart Basic just cause i use them more for home use for my Game controllers . They used to be cheaper then desertcart High capacity but are now about the same and someone once told me desertcart uses the same manufacturer as eneloop (at one time i was able to verify that as true but not sure about this current generation) I give them the edge to eneloop over desertcart right now because i believe their claim that bout 2000 charges. desertcarts only time will tell but if i get over 100 cycles out of desertcarts with no losee in capacity I may have a new #1 but for now these guys win. Review: Consistent quality as Always - Strong Performance with Good Reliability (Slightly Less Balanced Than Larger Batch) I recently tested this 8-pack of Panasonic Eneloop AA (standard capacity) batteries using an ISDT N8-Series smart charger in analysis mode at 0.7A with a 0.90V cutoff. All cells were tested under identical conditions. Performance Results * Average capacity: 2245 mAh (well above the 2000 mAh rating) * Internal resistance: ~170 mΩ average * Temperature during testing: Stable (28–31°C) * Cells tested: 8 Every battery exceeded the rated capacity, which is exactly what you expect from genuine Eneloops. 📊 Consistency & Observations Most cells clustered tightly in the 2160–2250 mAh range, showing solid consistency. One standout cell reached 2477 mAh, which is excellent for a standard capacity Eneloop. Internal resistance was very consistent across the board, indicating good overall cell health and reliability. Batch Comparison Note For reference, I previously tested a separate 16-pack of Eneloop AA batteries manufactured a couple months later (10/2025 vs this pack’s 07/2025). While both batches performed well above spec, the newer batch showed slightly tighter consistency across all cells. ✅ Pros * All cells exceed rated capacity * Reliable and consistent internal resistance * No weak or failing batteries * Expected Eneloop quality ⚠️ Cons * Slightly wider capacity spread compared to another batch tested * One high outlier makes the pack a bit less evenly matched Final Verdict This is still a strong-performing, reliable set of Eneloop batteries that delivers above-spec capacity and solid overall consistency. While not quite as tightly matched as a newer batch I tested, there are no weak cells here, and performance is excellent for everyday and high-drain devices. Recommended for anyone looking for dependable, long-lasting rechargeable AAs. These Japanese-made Panasonic Eneloops, as they have been for almost 3 decades, are still the best NiMH rechargeable batteries you can buy. In my opinion they are absolutely worth the cost verses cheaper Chinese made options. ## Features - LONG LASTING PERFORMANCE: Recharge eneloop AA rechargeable batteries up to 2100 times - POWERFUL NiMH RECHARGEABLE BATTERIES: eneloop AA Ni-MH pre-charged rechargeable battery deliver up to 2100mAh typical, 2000mAh minimum - PRE-CHARGED AND READY TO USE: eneloop AA 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 AA rechargeable batteries - EXTREME TEMPERATURES: eneloop rechargeable batteries can used in extreme temperatures, down to -4 deg Fahrenheit - QUALITY YOU CAN TRUST: These eneloop rechargeable AA 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 AA 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 | B00JHKSN5I | | Antenna Location | Remote Controls, Flashlights, Toys, Laptops, Remote Control Vehicles, Gaming Controllers | | Battery Capacity | 2000 milliamp_hours | | Battery Cell Composition | NiMH | | Battery Cell Type | NiMH | | Battery Weight | 27 g | | Best Sellers Rank | #5,084 in Health & Household ( See Top 100 in Health & Household ) #22 in AA Batteries | | Brand | Eneloop | | Compatible Phone Models | gaming consoles | | Customer Reviews | 4.8 out of 5 stars 17,283 Reviews | | Global Trade Identification Number | 00073096902022 | | Included Components | Panasonic BK-3MCCA8BA eneloop AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack | | Item Dimensions | 1.2 x 3.38 x 4.25 inches | | Item Type Name | Panasonic BK-3MCCA8BA eneloop AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack | | Item Weight | 14.06 g | | Manufacturer | Panasonic | | Model Name | eneloop | | Model Number | BK-3MCCA8BA | | Number of Batteries | 8 AA batteries required. | | Recommended Uses For Product | Remote Controls, Flashlights, Toys, Laptops, Remote Control Vehicles, Gaming Controllers | | Reusability | Rechargeable | | UPC | 675904017517 044112431888 073096902022 | | Unit Count | 8 Count | | Voltage | 1.2 volts | | Warranty Description | This product is guaranteed to be free from defects in materials and workmanship | ## Product Details - **Battery Capacity:** 2000 Milliamp Hours - **Battery Cell Composition:** NiMH - **Brand:** Eneloop - **Number of Batteries:** 8 AA batteries required. - **Recommended Uses For Product:** Remote Controls, Flashlights, Toys, Laptops, Remote Control Vehicles, Gaming Controllers ## Images ![Eneloop Panasonic BK-3MCCA8BA AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack - Image 1](https://m.media-amazon.com/images/I/71xaSEuPFLL.jpg) ## Available Options This product comes in different **Configuration, Size, Style** options. ## Questions & Answers **Q: What is the difference between the Panasonic K-KJ17KHCA4A Eneloop Pro vs the Panasonic K-KJ17MCA4BA? Which is a better choice to buy?** A: The pro cells hold about 25% more capacity under use before you have to charge it. That translates to longer run times for things like hiking GPS and high powered flashlights and wireless microphones in constant use. The trade off is that the pro cells don't retain a charge when stored which is good if you normally plan to drain the battery within a few days of charging it. In a TV or DVD remote control, the pro cells would have to be charged at least once every several months, where the regular cells will last for years without charging in remote controls that are not used daily. So far, I have never had an Eneloop battery ever leak, where I have had several expensive remote controls and headlamp LED's destroyed by leaking modern alkaline batteries. Modern alkaline batteries will often start leaking while still performing and still many years before the best used date has arrived. Modern warrantees for alkaline batteries only cover the battery that fails to perform, not the expensive device that was destroyed by the leaking alkaline battery. I have had several Duracell batteries start leaking while still unused in the original package stored in a cool dry place (basement) and still have a few years before the best used date has arrived. Today's alkaline batteries are junk. The standard Eneloop battery seems to be the most dependable battery I have ever found. They cost more, but the extra cost is worth it. Other brands of NiMH batteries I use often don't hold a charge in storage. The supposed lower voltage compared to alkaline is not the whole truth. Under extreme low power loads, alkaline battery voltage is higher, but under higher loads like cameras and flashlights, the alkaline battery voltage drops lower than NiMH battery within a second of the time the load is applied and then goes back up to resting voltage after the load is turned off. After an alkaline battery looses around 20% of its original charge, it is performing worse than a rechargeable NiMH battery and many devices like cameras can't take that drop in voltage. **Q: i just received the charger and i do not see any indicator lights on mine. anybody???** A: Just to update this - the chargers shipping now have hidden lights (unlike the product picture). To see them charger must be plugged in with batteries in place. NOTE: To clarify the paper comment - the batteries are shipped in the charger in the charging position. Before first use, remove all four batteries and you will find a small piece of cardboard paper at the top covering the positive charging contacts. This paper is to be discarded. Put the batteries back in position, plug in charger to working circuit and you will then see the now hidden lights under the white plastic "skin" below each battery. This is still true as of 11/2018. **Q: Do the Eneloop batteries require an Eneloop charger or can they be charged in other AA and AAA battery chargers?** A: The Sanyo/Panasonic eneloop cells can be recharged in any good-quality charger designed for NiMH batteries.For best battery lifespan, choose a 'smart' charger that has a charge time between 2 and 5 hours.Avoid slow, timer-based dumb charger that will over-charge your batteries, and 'ultra-fast' 30-minute chargers that will over-heat your batteries. **Q: Must you charge 4 batteries at a time OR can you charge, say 2 with 2 open slots?** A: The Panasonic BQ-CC17 can recharge 1, 2, 3 or 4 AA/AAA cells at once. You don't need to charge in pairs like in the case of old MQN06 charger. ## Customer Reviews ### ⭐⭐⭐⭐⭐ TL:DR - Best Batteries for Game Controllers and long term recharging *by M***F on November 6, 2015* These are seriously amazing I have tried many different Ni-MH rechargeable batteries and these are the best!

The ratings on the battery cover lists them at 1.2v, 1900 mAh. The batteries I received were fully charged and ready to use right out of the box. The Eneloop AA's hold a charge for a long time even when used for DSLR camera hot shoe flash units. I've been using one set on my cameras for over a year now and they still work great. Will try them for other applications and see how it goes. ## Frequently Bought Together - Eneloop Panasonic BK-3MCCA8BA AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack - Eneloop Panasonic BK-4MCCA8BA AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 8-Battery Pack - Panasonic BQ-CC55SBA Advanced eneloop Individual Rechargeable Battery 3 Hour Quick Charger with 4 LED Color Charge Indicator Lights --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://aruba.desertcart.com/products/1302023-eneloop-panasonic-bk-3mcca8ba-aa-2100-cycle-ni-mh-pre](https://aruba.desertcart.com/products/1302023-eneloop-panasonic-bk-3mcca8ba-aa-2100-cycle-ni-mh-pre) --- *Product available on Desertcart Aruba* *Store origin: AW* *Last updated: 2026-08-24*
