It fits the OEM part numbers 1512 90000 and 1226, restoring full motor power to units with depleted or failed original packs. Capacity is 2600mAh — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1512 Fido and 1226 Felix compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V battery platform, connector pinout, and BMS handshake protocol — so a single replacement cell covers the entire range. Voltage rail, physical dimensions (70.50 × 37.10 × 37.10mm), and pack orientation are identical across both platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the 1512 Fido motor assembly. The BMS held stable voltage under sustained suction load and did not trip the overcurrent cutoff during normal carpet operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Fido:\u003c\/strong\u003e\n    Do not leave the 1512 Fido sitting on its charging dock permanently. Continuous dock contact applies a low-level trickle charge after the pack reaches full, and Li-ion cells in this format degrade noticeably faster under that condition. Charge to full, then remove the unit from the dock.\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 1512 Fido\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the pack can deliver at full voltage — the pack voltage sags under load even though the indicator still reads mid-range. On the 1512 Fido, a partially blocked filter is the most common trigger: restricted airflow forces the motor to work harder, pulling current spikes the BMS registers as a load event. The indicator reads pack state-of-charge, not real-time motor voltage, so those two readings diverge. Check and clean the filter first, then retest — a clear filter drops motor draw back within the pack's rated output window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction blockage or a clogged filter causes the motor to exceed the pack's current threshold, the BMS shuts the output rail to protect the cells — usually for 3 to 5 seconds before resetting automatically. Clearing the blockage or filter restriction is the fix; the trip will keep recurring as long as the restriction remains. If the motor cuts out even on an unblocked, clean surface, check that pack voltage reads at least 14.0V under light load with a multimeter before concluding the battery is at fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426476982362,"sku":"BWCS-ETF122VX-1","price":305.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426477015130,"sku":"BWCS-ETF122VX-2","price":365.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426477047898,"sku":"BWCS-ETF122VX-3","price":410.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ETF122VX-1.webp?v=1779933373","url":"https:\/\/batteryweb.com\/products\/eta-1512-fido-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
