It fits the ER160, ER161, ER1511, and ER1610 among a wider range of compatible models. The cell measures 54.10 × 14.20 × 14.20mm and replaces OEM part numbers including WER160L2506, WER1411L2508, and WER2302L2509.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eER160 series compatibility:\u003c\/strong\u003e\n    These models share the same cell format, voltage rail, and internal connector layout. The same 1.2V Ni-MH cell services the motor drive circuit across all variants in this range — that is why one part number covers ER161, ER1511, and ER1610 alongside the base ER160.\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 an ER-series shaver body. The BMS accepted the cell without fault codes, and motor response under load matched the behaviour of an original cell at comparable state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePort drying before charge:\u003c\/strong\u003e\n    If you rinse the shaver head after use, let the charging port air dry completely before docking. Moisture bridging the charge contacts triggers a protection fault the shaver reports as a dead battery — not a charging error. Ten minutes face-down on a towel is enough.\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 ER160\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells used in shavers are susceptible to voltage depression when repeatedly charged from a shallow discharge. The shaver's charge indicator tracks voltage, not true capacity — so the indicator can show full while the usable capacity has already dropped. Daily top-up charging without a full discharge cycle compounds this over weeks. Running the shaver until the motor audibly slows before the next charge resets the voltage reference and slows fade.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor speed drops before the low-battery indicator lights up\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder motor load the cell voltage sags below what the circuit expects before the BMS cutoff threshold is reached. The shaver's indicator reads resting voltage, not load voltage — so the light stays off while the motor has already lost torque. This is a normal characteristic of an ageing or deeply cycled Ni-MH cell, not a shaver fault. Fitting a fresh cell and allowing one full charge cycle to 1.2V before first use restores consistent motor speed under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416127242330,"sku":"BWCS-BRF310SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416127275098,"sku":"BWCS-BRF310SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416127307866,"sku":"BWCS-BRF310SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRF310SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/panasonic-er160-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
