Which Xbox controllers this CELLONIC pack is listed for
The CELLONIC 400mAh rechargeable battery is listed for Microsoft Xbox One, Xbox One Elite, Xbox One S and Xbox One X controllers. That covers the main variants of the Xbox One controller family, so if your controller is one of those four, the listing is aimed at your device.
The pack is described as fitting the standard battery compartment for a direct swap, with no modifications required. That is the key fit claim to check against your own controller before ordering: the replacement is shaped to sit in the original compartment rather than needing adapters or trimming.
What the CELLONIC 400mAh pack specifies
- Batterij voor Microsoft Xbox One, One Elite, One S, One X Controller 400mAh van CELLONIC: 400 mAh capacity provides many hours of playtime. Capacity is the headline number for a controller battery; 400 mAh is the figure to compare if you are weighing this against another replacement pack.
Batterij voor Microsoft Xbox One, One Elite, One S, One X Controller 400mAh van CELLONIC - Batterij voor Microsoft Xbox One, One Elite, One S, One X Controller 400mAh van CELLONIC: 2.4 V output matches the original specifications. Voltage is the compatibility check that matters most; a 2.4 V output is stated to match the original specification for these controllers.
- Batterij voor Microsoft Xbox One, One Elite, One S, One X Controller 400mAh van CELLONIC: Compatible with Xbox One, One Elite, One S and One X controllers. This is the full compatibility list supplied for the pack, so it is the list to match against your own controller model.
- Batterij voor Microsoft Xbox One, One Elite, One S, One X Controller 400mAh van CELLONIC: Compact size fits the standard battery compartment for a direct swap. A direct-swap fit means the battery is intended to go into the existing compartment without modification.
What the listing does not confirm
The supplied information does not include charging time, number of charge cycles, or a step-by-step installation procedure. It also does not state whether the pack works with third-party charging docks or play-and-charge cables. If those details matter to you, treat them as unconfirmed rather than assuming they are supported.
The listing also does not give a battery life figure in hours; the 400 mAh capacity is the only runtime-related specification provided. Any claim of a specific number of hours would go beyond what is documented here.
Checks to make before you order
- Confirm your controller model: The pack is listed for Xbox One, One Elite, One S and One X controllers. Check the model name on your controller or its packaging before ordering.
- Check the battery compartment: The pack is described as fitting the standard battery compartment for a direct swap. If your controller uses a different battery arrangement, this listing may not be the right match.
- Decide whether 400 mAh is enough: The listing states 400 mAh provides many hours of playtime but does not give a specific hour count. If you need a precise runtime figure, that information is not supplied here.
- Consider the guarantee: The pack is backed by a guarantee from a battery specialist established in 2004. The exact guarantee terms are not detailed in the supplied information, so check them with the seller if they matter to you.
How this replacement compares with an original Xbox pack
The main trade-off with any replacement pack is certainty versus price. An original Microsoft pack is the known quantity, but the CELLONIC listing offers a 400 mAh, 2.4 V replacement that is stated to match the original specifications and to fit the standard compartment without modification.
What the listing does not provide is a direct comparison against the original pack's capacity, charging behaviour or lifespan. If you want a like-for-like specification match, the 2.4 V output is the strongest point of alignment supplied; the 400 mAh capacity is the figure to weigh on its own merits.
When this battery is the right choice
This pack suits you if you own an Xbox One, One Elite, One S or One X controller, your current battery no longer holds a useful charge, and you want a direct-swap replacement that fits the existing compartment without modification. The 2.4 V output is stated to match the original specification, and the 400 mAh capacity is the headline runtime figure.
It is less suited if you need documented charging times, a specific playtime in hours, or confirmation of compatibility with third-party charging accessories, because the supplied information does not cover those points. In those cases, ask the seller for the missing details before ordering rather than assuming they are supported.
