It fits the PCR-1350 L, PCR-2350 LX, NC-3337, and NC-3338 models. The battery slots into the underside battery compartment and restores autonomous cleaning operation when the original cell has degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePCR-1350 L \/ PCR-2350 LX \/ NC-3337 \/ NC-3338 fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector pinout, and physical form factor — 179 × 51 × 52mm — which is why one cell covers all four. The BMS on each model uses the same charge acceptance profile, so no handshake issues occur on swap.\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 14.4V Ni-MH test rig. The BMS accepted charge without triggering fault flags, and discharge held a stable voltage curve consistent with rated 2000mAh capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for Ni-MH cells:\u003c\/strong\u003e\n    Ni-MH chemistry is more sensitive to continuous trickle charging than Li-ion. Leave this robot on the dock only until charging completes, then remove it. Permanent dock connection accelerates capacity fade in Ni-MH cells faster than in most other chemistries.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low on the PCR-1350 L\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells show a gradual voltage sag under sustained motor load, which sets in well before the pack is fully discharged. On the PCR-1350 L, the suction motor draws more current on carpet or when the filter is partially blocked. That extra draw accelerates voltage sag, and the robot interprets the drop as normal operation rather than low battery. Cleaning the filter before each run keeps motor draw at rated levels and keeps voltage sag in check longer. If suction still drops early with a clean filter, the original cell has likely lost capacity — this replacement cell restores rated voltage under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a total battery failure. When the filter is restricted, the suction motor pulls above its rated current to maintain airflow, and the BMS cuts the circuit to protect the cell. After a few seconds the BMS resets and power returns. The fix is a clean filter — clear the filter mesh and check the brush roll for hair tangles, both of which force the motor to work harder. If cut-outs continue with a clean filter and clear brush roll, measure pack voltage under load; it should hold above 12V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428088610906,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428088643674,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428088676442,"sku":"BWCS-IRB400VX-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB400VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/sichler-reinigungs-roboter-pcr-1350-l-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
