It replaces OEM part BAT-120002 and restores power to units where the original cell has degraded. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBLT-1203A platform fit:\u003c\/strong\u003e\n    The BLT-1203A uses a 12V Li-ion architecture with a BMS that validates cell chemistry at startup. This replacement cell matches the voltage rail and connector pinout, so the device's power management circuit reads it correctly on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the BLT-1203A's startup self-test sequence and monitored BMS handshake. The protection circuit engaged correctly at full charge and held the low-voltage cutoff within the expected range for this cell chemistry.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interrupting or powering it off. Medical device BMS firmware runs a verification pass at startup — cutting power mid-sequence logs a false battery fault that persists until the next full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BLT-1203A runs a BMS learn cycle during its first few power-on sequences after a new cell is installed. If the device stalls mid-boot or displays an error, it usually means the BMS has not yet characterised the new cell's internal resistance profile. This is not a fault with the replacement battery. Power the device off fully, recharge to 100%, then restart — the boot sequence typically completes cleanly from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge of a new Li-ion cell, the BLT-1203A's charge IC applies a conservative current limit while it measures cell impedance. This causes the charge indicator to plateau below 100% longer than expected — sometimes stopping at 95–98%. This is the charge controller behaving correctly, not a capacity defect. Leave the device on charge until the indicator completes; it will reach full charge within the first two cycles. After that, the charge IC recalibrates and normal charge curves resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381466693722,"sku":"BWCS-BLT120MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381466726490,"sku":"BWCS-BLT120MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381466759258,"sku":"BWCS-BLT120MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLT120MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/bollywood-blt-1203a-replacement-battery-12v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
