It fits the AHTO platform used in operating rooms to deliver sterile fluid during surgical procedures. Voltage and cell chemistry match the OEM specification for this pump series.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAHTO platform compatibility:\u003c\/strong\u003e\n    The AHTO irrigation pump uses a fixed 16.8V Ni-MH pack with a specific connector and BMS handshake tied to that voltage rail. Swapping chemistry or voltage causes the pump controller to reject the pack outright. This replacement matches both the electrical spec and the physical footprint of OEM part numbers 250-070-602, 250-070-601, and B11533.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and load cycles on the AHTO pump. The BMS completed its self-test sequence, accepted the charge IC handshake, and held voltage under pump motor load without triggering a low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test cycle:\u003c\/strong\u003e\n    After installing this battery, let the pump complete its full power-on self-test without interrupting it. The AHTO's BMS runs a verification sequence at startup. Cutting power mid-sequence logs a false battery fault that persists until the next clean reboot — this is a device behaviour, not a fault with the cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AHTO pump BMS rejects a new Ni-MH cell on first boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AHTO's charge controller was calibrated against a known internal resistance profile from a cycled OEM cell. A fresh Ni-MH cell presents lower internal resistance and a slightly different charge curve, which the BMS can read as outside its acceptance window. This does not mean the replacement is faulty. One full charge-discharge cycle normalises the cell's internal resistance and aligns it with the BMS's learned threshold. Run this cycle away from the operating room before placing the battery into clinical rotation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePump alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS self-test threshold was set against a partially degraded OEM cell and the new cell's charge profile doesn't match what the controller expects to see at 16.8V full charge. The alarm is a threshold mismatch, not a capacity problem. Run one complete charge-discharge cycle on the new pack — most AHTO units recalibrate after a single full cycle and stop alarming. If the alarm persists after two full cycles, check that resting voltage after charge reaches 16.8V before reinstalling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381425111130,"sku":"BWCS-SKA250MD-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381425143898,"sku":"BWCS-SKA250MD-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381425176666,"sku":"BWCS-SKA250MD-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SKA250MD-1.webp?v=1778900681","url":"https:\/\/batteryweb.com\/products\/stryker-irrigation-pump-ahto-replacement-battery-168v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
