Designed for professionals who demand reliable, long-lasting power, these batteries maintain near-full charge over time and come with a handy carrying case for easy portability. ## Description The Powerex MHRAA4 Rechargeable AA NiMH Batteries (1.2V, 2700mAh) - 4-Pack is a package of 4 AA nickel-metal hydride (NiMH) batteries. They have a voltage of 1.2V and a capacity of 2700mAh. The batteries can be recharged hundreds of times, and because they have memory-free operation, they will not develop memory effect, which can cause batteries to hold less charge. These batteries will retain a charge at or near their full capacities even after hundreds of charges. A battery carrying case is included. Review: Longest Lasting AA Batteries, Period - I've owned and tested everything out there, and this is the best in terms of mAh yield. I own a half dozen sets of these, and they all test at about 2600 mAh after refreshing. For reference, the duracell "2650 mAh" batteries test at around 2500 typically. Yes eneloops are great batteries, and HOLD a charge like nothing else (unbeatable for photographers who leave them sitting in the camera bag for long periods), but they can't match the raw output these batteries give. These batteries are designed for people like myself (regular scanner user)who go through a set of batteries every few days to a week, so that self-discharge isn't really an issue. You can't go wrong with these batteries if you rotate batteries at least every 1-2 weeks. If you want batteries that sit for long periods and hold a charge, buy eneloops, but realize they don't have the endurance these have. *****TIP: If you are serious about battery performance, you need a good charger that can refresh batteries, and can test them, display actual capacity, and charge at various rates. Remember that a set of batteries is no better than the weakest in the set, and unless you test, you might never notice that one is weaker than the others. A good refresh charger can often bring this weaker battery up to snuff with the others, and you can see the test to prove it. If it remains weaker, you can match it with weaker batteries for matched sets. Keep in mind, even great batteries like the Powerex batteries, sometimes need to be run through refresh cycles when new to get them to full capacity. Batteries that sit for a while also benefit from a refresh. Check out the AccuPower IQ328 charger that runs about $35 if you look around. It does all of this, and helps you get the full value out of top of the line batteries. Also, if possible keep charged sets in your refrigerator to slow self-discharge. Good luck. Review: My experiences with Powerex 2700 - I've only had these for three months now. I've used them in two cameras. The Canon powershot sx10is, and my powershot A710is. I just got back from Walt Disney World. I shot a lot of video using the sx10is. I recorded entire shows/parades etc. No failures experienced.Shot all that video, and still had plenty of juice to take flash pictures. The sx10is has a monster zoom as well, so there's another bite out of the batteries as well. I've taken quite a number of pictures and video since owning these. What I also find refreshing is not finding them dead after a short space of time while not used. Finding dead batteries started to be common with another manufacturer I won't name. I also use these batteries in my portable bearcat scanner. I've gotten around 16 to almost 17 hours of continuous on time out of these powerex batteries. I have two of the Powerex eight cell smart charger. Since all I use are AA batteries, this charger is ideal for me. When I bought these batteries, the very first thing I did was condition them. Based on the results i'm getting, i'd say that's the way to get started. I've read some of the reviews here. It's not my intention to question anyones negative experiences here. Sometimes things just don't work as well as they should. That happens unfortunately. As far as longevity goes, my experiences with batteries like these is, they only have a limted life span. (like us, only shorter) They can only be charged/discharged and charged again so many times. I feel that if I can get a complete year of this kind of performance, then I feel i've gotten my money's worth. Digital cameras are extremely power hungry and put one heck of a drain on batteries, or so it sure seems to me. Overall, so far, i'm happy with the performane. If things turn sour, I will update this review to tell you. I've eaten crow before. Just pass the salt if I come back with bad news. ## Features - Nickel-Metal Hydride (NiMH) Chemistry - Voltage of 1.2V and a capacity of 2700mAh - Batteries can be recharged hundreds of times, and because they have memory-free operation, the will not develop memory effect, which can cause batteries to hold less charge - These batteries will retain a charge at or near full capacities even after hundreds of charges - A battery carrying case is included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A9KTPY8 | | Amperage | 4 Amps | | Antenna Location | GPS | | Battery Capacity | 2700 Milliampere Hour (mAh) | | Battery Cell Type | NiMH | | Best Sellers Rank | #646,918 in Health & Household ( See Top 100 in Health & Household ) #1,957 in AA Batteries | | Brand | Powerex | | Customer Reviews | 4.4 4.4 out of 5 stars (1,014) | | Global Trade Identification Number | 00802366141539, 00802366141614 | | Item Dimensions | 3.5 x 0.5 x 5 inches | | Item Weight | 0.4 Pounds | | Manufacturer | Maha Communications and Electronics | | Model Name | Rechargeable batteries | | Model Number | MHRAA4 | | Number of Batteries | 4 AA batteries required.

Of 12, 2 batteries so far are just under 2500mAh with the rest now at just over 2500mAh. I may try what Radio Control (RC) users try is a repetitive discharge/charge cycle to get some of the cells into shape, but to date have used the Break-in and refresh & analyze modes from my MH-C9000 charger. An 8-cell Maha Powerex charger is coming down the road - it's the best way to go to rotate spare batteries while some of the more time consuming charge modes are used. I want to point out that virtually nothing these days rounds down (they all stretch numbers up): MP3 players, hard drives, etc... all stretch capacities and levels. For that reason I rate this 4 stars. That said, if ALL batteries are rated like this, then these AA batteries still are better quality in terms of how long they hold onto their charge. They have performed well above average compared to Energizer 2100 & 2300mAh batteries and Energizer & Duracell alkaline batteries I've tried in a new Garmin Oregon 400t GPS - nearly double the life! Keep in mind: If someone were to use regular retail store NIMH batteries without a smart charger, then they would otherwise just attribute low battery life to poor battery quality or that their device is a power hog. These batteries are high capacity in comparison to what's out there, last as long or longer compared to the competition (like industry leader Sanyo), and can also be found at national stores like Batteries Plus. They are good batteries even if they follow the crowd and "round down" with their capacity rating. ## Frequently Bought Together - Powerex MHRAA4 AA 2700mAh 4-Pack Rechargeable Batteries - Powerex MH-C980 Turbo Charger Analyzer for AA/AAA Batteries - Powerex PRO AA High Capacity Rechargeable NiMH 1.2V, 2700mAh - 16 Batteries With Holders --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/3048942-powerex-mhraa4-aa-2700mah-4-pack-rechargeable-batteries](https://www.desertcart.us/products/3048942-powerex-mhraa4-aa-2700mah-4-pack-rechargeable-batteries) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
