It slots into the shaver body in place of the original cell. Dimensions are 49.00 × 29.00 × 14.50mm — measure your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4510 series shared cell platform:\u003c\/strong\u003e\n    These models run the same 2.4V single-cell Ni-MH configuration, the same physical footprint, and the same motor voltage rail — which is why one cell fits the entire group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a 4510 chassis, confirmed the motor started cleanly under load, and verified the charge circuit accepted the cell without fault codes or thermal cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation conditioning on Ni-MH shavers:\u003c\/strong\u003e\n    Braun's charge circuit calibrates the low-battery threshold against cell voltage history. After fitting a new cell, run the shaver until the motor audibly slows, then charge fully — do this twice before trusting the indicator light.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor speed dropping before the indicator shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells show a steeper voltage sag under motor load than the charge indicator anticipates. The shaver's indicator reads resting voltage, not load voltage, so it can still show mid-charge while the motor is already starved. A cell that has degraded through repeated shallow cycles loses internal resistance control first — the indicator drifts later. A fresh 2.4V cell restores the load voltage margin the motor needs to hold full speed through a complete shave.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShaver not charging after water exposure during cleaning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWater bridging the charging contacts triggers a BMS protection response that the shaver reports as a dead battery rather than a charging fault — so the cell takes the blame. Before assuming a failed cell, dry the charging port and contacts thoroughly; a warm, dry environment for two to three hours is enough. Then connect the charger and check for a charge indicator response within five minutes. If the indicator activates, the fault was moisture, not the cell; if there is still no response after the port is confirmed dry, the cell voltage has likely dropped below the charger's 2.0V detection floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416131960922,"sku":"BWCS-PHN282SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416131993690,"sku":"BWCS-PHN282SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416132026458,"sku":"BWCS-PHN282SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHN282SL-1.webp?v=1779760427","url":"https:\/\/batteryweb.com\/products\/braun-4510-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
