Direct replacement battery

This lithium-polymer cell restores power to Logitech UE310, UE3500 and UE4500 wireless headsets. It matches the original 533-000069 and AHB521630 part numbers for a straight swap without soldering. Buyers who need a different connector or a higher capacity will not be served by this model.

Normal use profile

The 3.7 V, 220 mAh pack delivers 0.81 Wh in the same 32.20 x 17.20 x 4.72 mm footprint as the factory unit. Li-Polymer chemistry keeps self-discharge low during storage and runs cool during typical listening sessions. No active cooling or special charging routine is required beyond the headset's own circuitry.

Upgrade context

This cell replaces a depleted original in the headsets listed above and in G Pro Wireless, G502, G304, MX Vertical, G703 Lightspeed and H600 models that share the same connector. The jump is worth it when run-time has fallen below usable levels; it does not increase capacity beyond the stock 0.22 Ah rating.

Questions about this item

How do I install the DS-CS-LOE310SL and which step do people get wrong?

Open the headset, disconnect the old cell, match the connector shown in the listing image to your H600 connector, insert the 32.20 x 17.20 x 4.72 mm pack, and reassemble; the common error is fitting the wrong H600 generation connector.

What maintenance or replacement will this 3.7V 220mAh Li-Polymer cell need later?

The 0.22 Ah pack loses capacity over charge cycles; replace it when run-time on your UE310, UE3500 or UE4500 drops noticeably.

What limit appears first under sustained use on this 0.81 Wh battery?

Voltage sag under continuous drain cuts listening time before the 220 mAh rating is reached, especially on power-hungry models like G502 or G703 Lightspeed.
