It replaces OEM part numbers EY9L32 and EY9L32B. The pack slots into the same slide-rail mount and uses the same BMS handshake as the original Panasonic cells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEY3732 and EY7430 platform compatibility:\u003c\/strong\u003e\n    Both the EY3732 and EY7430 run the same 10.8V rail with an identical connector footprint and BMS communication protocol. One pack covers the full range without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through trigger-pull inrush events on the EY3732 drill. The BMS held across repeated motor-start current spikes without tripping overcurrent protection during normal drilling sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load break-in on this drill:\u003c\/strong\u003e\n    Run the EY3732 at half load — light drilling, no high-torque fastener driving — for the first two charge cycles. This lets the BMS log the motor's inrush current profile and calibrate overcurrent thresholds before you push maximum torque.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on EY3732 motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless drill, the motor draws a brief but sharp inrush current — often three to five times the running draw. On a new or recently stored pack, the BMS may read that spike as an overcurrent event and cut power immediately. This is not a fault with the pack; it is the protection circuit doing its job before it has profiled the motor load. Running two break-in cycles at reduced load trains the BMS to recognise the EY3732's normal inrush signature and raises the effective trip threshold for real-world use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs that sit unused for several months can drop below the charger's minimum acceptance voltage — typically around 2.5V per cell. When that happens, the Panasonic charger blinks an error pattern and refuses to begin a charge cycle. The fix is a brief trickle pre-charge to bring each cell back above 3.0V before the charger switches to its normal CC\/CV profile. If your charger supports a recovery or conditioning mode, use it; otherwise, a compatible charger with a wake-up function will bring the pack back to full acceptance voltage before proceeding.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416008294490,"sku":"BWCS-PEZ373PW-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416008327258,"sku":"BWCS-PEZ373PW-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416008360026,"sku":"BWCS-PEZ373PW-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PEZ373PW-1.webp?v=1779759303","url":"https:\/\/batteryweb.com\/products\/panasonic-ey3732-replacement-battery-108v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
