It replaces the original rechargeable cell when the shaver stops holding a charge or cuts out before the low-battery indicator triggers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e100 \/ 2100 \/ 2200 \/ 2205 series fit:\u003c\/strong\u003e\n    These models share the same 2.4V single-cell Ni-MH platform, identical physical footprint (49 × 29 × 14.5mm), and the same charge-management circuit inside the shaver body. One replacement covers the full series.\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 the shaver's own internal charging circuit. The BMS accepted the cell without fault flags, and voltage held steady through a full discharge curve before dropping at the expected cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCharging port care after rinsing:\u003c\/strong\u003e\n    If you rinse the shaver head under water, let the housing air-dry for at least 30 minutes before placing it back on the charging dock. Moisture bridging the charging contacts can trip a BMS protection fault the shaver reports as a dead battery — not a charging error.\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 charging on the Eltron shaver\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in shavers degrade faster when charged daily from a shallow discharge. The charge circuit tops up from 70–80% rather than running a full cycle, and over time the cell develops a reduced effective capacity — the indicator still reads full, but the shaver cuts out earlier each week. This is not a fault the BMS reports; it shows up as progressively shorter use before speed drops. Replacing the cell and allowing it to fully discharge before the first recharge resets the cycle baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor speed drops before the low-battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells exhibit voltage sag under the motor's rotational load before the BMS reaches its hard cutoff. The shaver motor draws a current spike during dense beard passes, pulling cell voltage below the level needed to maintain full speed — even though the indicator shows charge remaining. This is a cell condition issue, not a motor fault. A fresh cell at full charge holds voltage flat under the same load; if the replacement cell also sags early, check that the charging dock contacts are clean and making firm connection before concluding the cell is at fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416130093146,"sku":"BWCS-PHN282SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416130125914,"sku":"BWCS-PHN282SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416130158682,"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\/eltron-100-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
