Replacement battery for Corsair H2100 headset

The Centenex Electronics DS-CS-CRH210SL is a lithium-polymer cell built to fit the Corsair H2100 wireless gaming headset. It restores original runtime for gamers and remote workers who rely on the headset daily.

Thermals noise and power draw in normal use

The 3.7 V 700 mAh pack delivers 2.59 Wh of energy with low self-discharge typical of Li-Polymer chemistry. It runs cool during extended sessions and adds no audible noise to the headset.

Capacity and voltage match the original spec

The cell provides exactly .7 Ah at 3.7 V, matching the MH45908 part number used in CA-9011127-NA and CA-9011136-AP models. Buyers needing a different voltage or a higher milliampere-hour rating should look elsewhere.

Questions about this item

How do I install the Centenex DS-CS-CRH210SL battery in my Corsair H2100 headset, and what step is often missed?

Open the left ear cup, disconnect the old pack, and connect the new 3.7 V 700 mAh Li-Polymer unit; the step most people miss is tucking the flat 50.90 x 33.40 x 3.70 mm cell fully into the recess so the cover snaps shut without pinching the wires.

What maintenance or replacement will this 0.7 Ah Li-Polymer pack need over time?

Expect gradual capacity loss after several hundred charge cycles; when run time drops below roughly half of the original 2.59 Wh rating, replace the pack with another DS-CS-CRH210SL unit.

What limit appears first during a long gaming session with this 700 mAh replacement battery?

The 2.59 Wh capacity typically runs out before the headset’s thermal limits are reached, so plan on recharging after extended use.
