Ikea LADDA 2450mAh - $11.99/4pack
This is taken from IKEA USA official website as of January 12th, 2026. The eneloop deal is better.
Community Reviews
Panasonic Eneloop AA batteries stand out for long life, reliable charge retention, and strong performance in high-drain gear like Yale locks, Roku remotes, Xbox controllers, and motion sensor lights. The standard 2100mAh cells are praised for lasting years, with some still working after a decade or more, and the made in Japan packaging adds confidence. The main cautions are price versus IKEA LADDA or other alternatives, and the need for a sensible charger because very fast charging can hurt longevity. The 2450mAh version can also be too thick for some devices, so this is a durable everyday pick if fit and charging speed are handled carefully.
People who rotate rechargeable batteries and care about long service life, because standard-capacity cells can last 10 to 15 years or more with slow charging.
Households powering high-drain remotes and controllers, because these batteries hold charge for years and keep working in devices that burn through alkalines.
Owners of smart locks and keypad locks, because they can run for months in Yale locks and about a year in fingerprint locks.
Gamers using Xbox controllers, because these batteries last for days and work well as swap-in packs for quick reloads.
Shoppers who need the shortest possible charge time, because slower charging is favored for longevity and fast chargers can run hot.
People using a rechargeable dock that charges through a controller USB port, because these batteries may work in the controller but not in that dock.
Devices that need alkaline-like voltage behavior, because NiMH cells sit at 1.2 volts and can trigger low-battery warnings in alkaline-designed gear.
Devices that need a thicker AA cell, because the 2450mAh version can be slightly thicker and may not fit some battery compartments.

With Nickel-based batteries, you DO NOT want to fast charge them, because heat is bad and shortens overall lifespan of the batteries.
My go-to recommendation is the Powerex MH-C9000 (either the original or newer Pro version; the newer one is smaller and remembers your last used settings, otherwise they are identical).
With this charger, and SLOW charging my batteries (maximum 200mA for AAA or 300mA for AA), I have only had ONE eneloop fail on me in under 10 years, and can otherwise easily get 12-15 years out of eneloops.
As for specific chargers to AVOID, I haven't seen them around a whole lot lately, but DO NOT buy any chargers from LaCrosse Technology. They may look nice, but were plagued by bad power supply issues that resulted in overheating and in a few cases, fire!
With young kids and numerous controllers/remotes/etc, many of my eneloop AAs have lasted 15-20 years.
I've not seen a NiMH specific Opus charger before (I usually see those in discussions about Li Ion batteries), but it looks similar to my Powerex MH-C9000 but with a more cramped display. Intelligent chargers that let you define the charge rate, and can do break-in/battery analysis tasks are definitely the way to go.
NiMH is 1.2V per cell. Using these in a device that demands alkalines will probably work, but will probably start in a "low battery warning" state and hold there for quite a while.
Li Ion... are 3.6V cells. To make a AA cell, they have a buck converter in the cell to drop the voltage to 1.5V. This is how they fudge things and advertise "constant 1.5v output" (and because of this, they don't work well in high drain devices, as their current output is limited to the buck converter's capability).
When you use these in a device that is made for alkalines, they'll show as full, but as they drain, the battery meter might not even be able to warn you of the batteries getting low, as they can jump from 1.5v output to just being dead.
There is no rechargeable battery chemistry that can mimic the exact alkaline voltage output curve from fresh to dead.

With only one exception, all my eneloops have lasted at least 12 years. The Amazon ones I've tried, most failed around the 5 year mark, with just a couple of them making it close to 7.
I also use their charger [amazon.com]to recharge my Eneloops, and it's been goo as well
That said--when you get into the "high capacity" NiMH batteries, in general the higher per-charge capacity comes at a cost of a much shorter lifespan of the cell, typically only lasting somewhere in the 5-7 year range, as opposed to standard capacity eneloops easily doing 10-15 years, possibly more.

I am seeing that price for the AAAs.
