It restores cordless operation to a pump that has lost charge capacity or stopped holding a charge altogether. OEM part numbers 919.7010, 67060, and 101034761 all reference this same cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFreestyle Pump platform fit:\u003c\/strong\u003e\n    The Freestyle uses a specific 7.4V two-cell Li-ion pack with a BMS that negotiates charge state with the pump's onboard charge IC. Voltage, connector pinout, and cell dimensions must all match — a generic Li-ion pack at the same voltage will not complete the handshake and the pump will flag a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Freestyle's charge IC and confirmed the BMS communicated correctly across charge and discharge. The pack accepted a full charge without triggering fault flags and held voltage within spec under the pump motor's draw profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test:\u003c\/strong\u003e\n    After fitting this battery, let the Freestyle complete its full power-on sequence without interruption. The pump runs a BMS verification check at startup. Interrupting it before the sequence finishes can log a false battery fault that stays active until the device is powered down and rebooted from scratch.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Freestyle charge indicator stalls before reaching 100% on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Freestyle's charge IC applies a conservative current limit when it detects a cell it has not previously profiled. On the first charge, the IC holds the termination voltage lower than normal and cuts off early — the indicator may stop at 85–90% and stay there. This is the charge controller being cautious, not a fault with the cell. Running one complete charge-to-discharge-to-charge cycle allows the IC to update its profile and the indicator will reach 100% on the second charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFreestyle powers on briefly then shuts off within seconds of starting a session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a replacement cell has been in storage long enough for self-discharge to pull it below the BMS recovery threshold — typically under 6.0V for a 7.4V two-cell pack. The pump draws enough current at motor start to trip the BMS undervoltage cutoff before the cell has had a chance to recover. Connect the pump to the charger and leave it for a minimum of 30 minutes before attempting to power on — the charge IC will trickle current into the cell until it clears the recovery threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381420523610,"sku":"BWCS-MEF919MD-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381420556378,"sku":"BWCS-MEF919MD-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381420589146,"sku":"BWCS-MEF919MD-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MEF919MD-1.webp?v=1778900662","url":"https:\/\/batteryweb.com\/products\/medela-freestyle-breast-pump-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
