It replaces the original cell when the shaver no longer holds charge or the motor weakens during use. Voltage and chemistry match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEco XP platform fit:\u003c\/strong\u003e\n    The Eco XP runs a single Ni-MH cell at 3.6V nominal to drive the cutting motor and maintain consistent blade speed. The connector orientation and cell dimensions — 45.60 × 19.70 × 19.70mm — must match the original housing bay; this cell meets those dimensions directly.\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 bench, monitoring the BMS response at low-voltage cutoff. The cell accepted a full charge cycle without tripping protection and held voltage through discharge without unexpected cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-rinse charging precaution:\u003c\/strong\u003e\n    If you rinse the Eco XP under water, let the charging port air dry for at least 30 minutes before docking. Moisture bridging the charging contacts can trigger a BMS protection fault that the shaver reports as a dead battery rather than 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 Eco XP\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in shavers are prone to capacity drift when charged daily before the battery is meaningfully depleted. The charge controller in the Eco XP uses a delta-V detection method to determine end-of-charge — repeated shallow cycles compress the voltage curve, making it harder for the controller to detect a true full charge. Over time, the cell stores less energy per cycle even though it reads as fully charged on the indicator. Allowing the shaver to run down to motor slowdown before recharging resets this drift and lets the cell recover usable capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShaver motor slowing before the low-battery indicator activates\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not an indicator fault. Under motor load, an aged or depleted Ni-MH cell drops terminal voltage faster than the shaver's monitoring circuit can register. The indicator measures resting or near-resting voltage, so it lags behind the actual voltage the motor sees during a cutting stroke. The result is the motor losing speed — and shaving performance — while the indicator still shows charge remaining. Replacing the cell resolves the sag; a fresh 700mAh Ni-MH cell maintains closer to 3.6V under load through most of its discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416136319066,"sku":"BWCS-WXH70SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416136351834,"sku":"BWCS-WXH70SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416136384602,"sku":"BWCS-WXH70SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WXH70SL-1.webp?v=1779760443","url":"https:\/\/batteryweb.com\/products\/tondeo-eco-xp-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
