Best Rechargeable AA Batteries for Xbox Controllers in 2026

The standard Xbox Wireless Controller runs on two AA batteries, and Microsoft sells its own rechargeable pack as the alternative. AA cells have real advantages: a charged spare pair swaps in within seconds, and a worn-out cell is easy to replace. The question is which AA to use.

This guide sets out what Microsoft says first, then compares the options by the energy they store. We have not run controller runtime tests. Where this guide compares runtimes, the figures are estimates worked out from each cell’s capacity, and the math is shown.

What Microsoft Says

Microsoft’s support page, Using batteries in your Xbox Wireless Controller, gives two ways to power the controller: AA batteries, or the rechargeable battery pack from its Play & Charge Kit (for current controllers with a USB-C port, that is the Xbox Rechargeable Battery + USB-C Cable). On AA batteries, the page says:

• If you’re not using Microsoft’s pack, use only AA batteries with the LR6 designation (alkaline).
• The same page then recommends rechargeable AA with the HR6 designation (NiMH) for the best performance. They don’t charge in the controller; charge them the way the battery maker recommends.
• The battery indicator’s accuracy can vary with battery type and brand.

The page does not mention lithium or lithium-ion AA. SCIGOLD AA is a 1.5V lithium-ion rechargeable, so it is neither of the two types Microsoft names. It is standard AA size and holds about 1.5V, like a fresh alkaline, for most of its charge, but that is our description of the cell, not an approval from Microsoft. Follow your controller’s manual, which is also where Microsoft points you for battery safety information.

Microsoft publishes its own runtime ratings on its product pages. It tested preproduction units and says battery life varies significantly with headsets, accessories, usage and other factors.

Comparing AA Options by Capacity (Estimates)

In the same controller, playing the same games, runtime per charge should scale with the energy the cells store. The estimate below assumes the controller draws about the same power whatever cells are in it and can use each cell’s rated energy. It is not a measurement: headsets, rumble, temperature and cell age all change real runtimes. SCIGOLD’s figure is SGS-measured; the other figures are manufacturer-reported.

The math: estimated runtime = energy per pair ÷ 8,880 mWh. For Eneloop Pro, 6,240 ÷ 8,880 = about 0.70, so a pair of Eneloop Pro should give about 70% of what a pair of SCIGOLD AA gives in the same controller. Put the other way round, SCIGOLD AA should run about 1.42 times as long per charge as Eneloop Pro, and about 1.3 times as long as the highest-capacity NiMH.

Energizer gives no mWh figure for its Ultimate Lithium AA. Our estimate comes from the constant-power chart in its L91 datasheet: roughly 4,200 mWh at a 1 W draw and roughly 5,000 mWh at 0.1 W, so we use about 4,500 mWh. At a light draw it may run somewhat longer than the table shows.

Alkaline isn’t in the table. An alkaline cell’s usable energy depends heavily on how hard it is worked, and we don’t have a figure for a controller’s load that we would stand behind. Microsoft’s up-to-40-hour AA rating is the best reference for it.

The Battery Icon and Cell Voltage

An AA cell can’t tell the controller how much charge it has left, so the controller has to estimate it, and Microsoft notes that the indicator’s accuracy can vary with battery type and brand. The three chemistries behave differently:

• Alkaline starts at about 1.5V and falls gradually as it drains.
• NiMH runs at about 1.2V for most of its charge, so the icon may read lower than the charge that is actually left.
• SCIGOLD AA has a built-in regulator that holds its output at about 1.5V for most of the charge; near empty, the output drops to about 1V. Expect the icon to read high for most of the charge and drop late, so treat red as your cue to swap, and keep a charged spare pair ready.

We haven’t logged icon behavior in a controller; this is how the voltages differ, not a test result.

Disposable Lithium vs Rechargeable

By our estimate from Energizer’s datasheet (see above), Energizer Ultimate Lithium stores about 4,500 mWh per cell, about the same as SCIGOLD AA, so by capacity a pair should run about as long, or somewhat longer at a light draw. The difference is cost. At $1.50 to $1.87 a cell on Amazon in September 2026 ($11.99 for 8, $7.49 for 4), every pair you run down costs about $3.00 to $3.75. A SCIGOLD Kit, $55.99 for 4 cells plus the Pocket Charging Case (CW505) they need, costs about the same as 15 to 19 pairs of disposable lithium, and each SCIGOLD cell is rated for 1,600 cycles, keeping at least 70% of its capacity.

Xbox Rechargeable Battery vs Rechargeable AA

Microsoft’s pack for current controllers is the Xbox Rechargeable Battery + USB-C Cable ($24.99 at the Microsoft Store). Microsoft says the older Xbox One Play & Charge Kit also works in current controllers if you charge it with a USB-C cable instead of the one in the kit. How it compares with a SCIGOLD Kit for one controller:

Which to pick: Microsoft’s pack costs less up front and stays within Microsoft’s guidance; it suits players who don’t mind a cable during low-battery moments. Rechargeable AA suit players who want a charged spare pair ready to swap, or who already charge AA cells for other devices, with the caveat above about the battery types Microsoft lists.

Xbox Elite Series 2: No AA Option

The Xbox Elite Wireless Controller Series 2 (including the Core) doesn’t take AA batteries. Microsoft’s support page says it has an internal rechargeable battery and doesn’t need AA batteries or the Play & Charge Kit, with up to 40 hours of battery life when used wirelessly without a headset. When that battery wears out, Microsoft sells a replacement battery that owners can fit themselves. Nothing in this guide applies to the Elite.

Setup: SCIGOLD AA in an Xbox Series Controller

If you decide to use SCIGOLD AA after checking your manual:

1. Charge to full. SCIGOLD AA cells charge in the Pocket Case (CW505) or the Home Case (CW508), not on their own and not in the controller. Plug the case into a USB-C source; a full charge takes about 2.5 hours from a 5V/3A source.
2. Install both cells. Turn the controller over, slide off the battery door, and insert both cells matching the polarity markings in the compartment. Use two cells from the same set, charged together.
3. Check the level. The battery indicator is in the upper-right corner of any screen on your Xbox console.
4. Play normally. The icon will likely stay high for most of the charge, so don’t read much into it until it drops.
5. Swap and recharge. When the icon turns red, swap in your charged spares and recharge the empties in the case.

Summary

• Microsoft names two AA types for the Xbox Wireless Controller: alkaline (LR6) and, for the best performance, rechargeable NiMH (HR6). It doesn’t mention 1.5V lithium-ion AA, so check your manual before using one.
• Microsoft rates the controller at up to 40 hours on AA batteries and up to 30 hours per charge on its own rechargeable pack.
• By capacity, SCIGOLD AA at 4,440 mWh, SGS-measured, should run about 1.3 times as long per charge as the highest-capacity NiMH AA and about 1.4 times as long as Eneloop Pro. These are estimates, not test results.
• A SCIGOLD Kit ($55.99) covers one controller with a charged spare pair; the Family Bundle ($73.99) covers two.
• The Xbox Elite Series 2 has a built-in battery and takes no AAs.
