It matches the original cell chemistry, voltage, and physical form factor. Capacity is rated at 24Wh per the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTop-5300, Top-3300, Top-2200, TMP-S1010 compatibility:\u003c\/strong\u003e\n    These four models share a common 12V Ni-MH battery platform with the same connector pinout and BMS communication protocol. Swapping between models on this list does not require firmware changes or recalibration — the charge management circuit reads the same cell signature across all four.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the Top-5300 platform. The BMS handshake completed normally, charge IC accepted the cell without fault codes, and the device passed its post-charge self-test on the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test sequence:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification routine at startup — cutting power mid-sequence causes a false battery fault flag that sticks until the next clean reboot from a fully charged state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Top-5300 logs a battery fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMedical device charge controllers are calibrated to OEM cell characteristics — internal resistance, temperature rise curve, and voltage recovery profile. A new replacement cell behaves slightly outside those learned parameters on cycle one, which some firmware versions log as a soft fault. This is not a defective battery. Run one complete charge-discharge cycle, and the BMS resets its baseline to match the new cell. The fault clears without any manual intervention after that cycle completes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge, the device's charge IC applies a conservative current ceiling to an unknown cell — it hasn't built a charge history yet. The display may stop at 85–95% and show full readiness, but the cell has not reached its actual capacity ceiling. This is the charge IC protecting the cell, not a fault. Run the device down to its low-battery threshold and recharge fully once — after that cycle, the indicator reads accurately at 12V nominal off charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381478260826,"sku":"BWCS-SWZ530MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381478293594,"sku":"BWCS-SWZ530MD-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381478326362,"sku":"BWCS-SWZ530MD-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SWZ530MD-1.webp?v=1778901067","url":"https:\/\/batteryweb.com\/products\/top-corporation-top-5300-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
