It fits the original battery bay directly and works with the device's existing charging circuit. Use the capacity figure from the product data — 2000mAh (4.8Wh) — not third-party listings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCentrimed and Sarnes 9602 compatibility:\u003c\/strong\u003e\n    Both devices share the same 2.4V battery rail, connector footprint, and BMS handshake protocol — the same cell pack fits either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and load discharge on the Centrimed platform. The BMS responded correctly at both charge termination and low-voltage cutoff with no false trips under motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCharging port care on a surgical clipper:\u003c\/strong\u003e\n    Surgical clippers are frequently wiped down with isopropyl or chlorhexidine solutions. These liquids wick into the charging port. Before connecting the charger, let the port air-dry for at least 10 minutes after any wipe-down — residual moisture bridges the contacts and triggers a BMS protection fault the device reports as a dead battery.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from daily partial cycling on the Centrimed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in surgical clippers are often topped up on a dock after short use sessions rather than run to a low state first. This shallow-cycle pattern compresses the usable voltage window over time. The cell capacity slowly drops, but the charge indicator recalibrates around the new range and hides the degradation. The first visible sign is motor speed trailing off well before the low-battery indicator activates.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShaver warm to touch during extended clipping sessions\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Centrimed's compact housing gives heat from both the motor and the discharging Ni-MH cells nowhere to go. Warmth on the case during a long session is normal — it is the combined thermal output of motor work and the internal resistance of the Ni-MH chemistry under sustained load. If the device cuts out hot, the BMS has hit its thermal threshold, not a voltage cutoff. Let the unit cool to room temperature for five minutes, then power it on to confirm it resumes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416135925850,"sku":"BWCS-PHS920SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416135958618,"sku":"BWCS-PHS920SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416135991386,"sku":"BWCS-PHS920SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHS920SL-1.webp?v=1779760424","url":"https:\/\/batteryweb.com\/products\/3m-centrimed-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
