It fits the Omni 50 Plus and restores cordless audio playback when the original cell no longer holds a usable charge. Cell dimensions are 108.20 x 51.00 x 17.35mm — confirm these against your pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOmni 50+ platform fit:\u003c\/strong\u003e\n    The Omni 50 and Omni 50 Plus share the same battery bay, connector pinout, and BMS handshake logic. Both models draw from the same 7.4V rail to feed the amplifier board and Bluetooth radio simultaneously. Either model accepts this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles on the Omni 50+ and confirmed the onboard BMS accepted the cell without fault flags. Protection circuits tripped correctly at the low-voltage cutoff, and the fuel gauge reported capacity accurately after two full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge routine for the Omni 50+:\u003c\/strong\u003e\n    Let the speaker run down below 20% at least once a month before recharging. The Omni 50+ is commonly left on a desk and topped off constantly — this shallow-cycling pattern causes fuel gauge drift and accelerates cell degradation faster than periodic full discharges do.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs a lithium-polymer cell ages, its internal resistance climbs. When the amplifier pulls a high current burst — loud bass transients or maximum volume — the pack voltage sags below what the amp needs to operate cleanly. The speaker clips the audio signal before the battery indicator shows critical. This is voltage sag under load, not a capacity problem. A fresh cell with lower internal resistance eliminates the sag, and clean audio returns at full volume. Charge the replacement fully before the first long session, then confirm the battery indicator stabilises above 3.7V per cell under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOmni 50+ warm to the touch after an hour of playback\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Omni 50+ houses the amplifier board and battery pack inside a fabric-wrapped enclosure with limited airflow. During extended playback, amplifier heat and battery discharge heat accumulate together. A degraded cell with high internal resistance generates more heat under the same current draw, making the housing noticeably warmer than normal. A fresh pack with low internal resistance reduces the battery's heat contribution. If the speaker still runs hot with a new cell, check that the fabric grille is not blocked during use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416189239386,"sku":"BWCS-HKM500SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416189272154,"sku":"BWCS-HKM500SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416189304922,"sku":"BWCS-HKM500SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HKM500SL-1.webp?v=1779760725","url":"https:\/\/batteryweb.com\/products\/harmankardon-omni-50-replacement-battery-74v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
