It matches the original voltage and capacity spec exactly. Physical dimensions are 86.95 × 71.05 × 4.30mm — measure your bay before ordering if your unit has been previously repaired.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e59 Titanium and A59 Titanium fitment:\u003c\/strong\u003e\n    Both model names reference the same hardware platform. The connector pinout, BMS communication protocol, and cell footprint are identical across the 59 Ti lineup, so one cell covers both designations.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the cell through charge and discharge under screen-on and modem-active loads. The BMS held cutoff correctly at low voltage and accepted charge current without thermal events through a full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge-to-charge cycle at standard current. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated measurement baseline.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Archos 59 Titanium after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a faulty cell. When the modem transmits or the screen brightness peaks, the new cell draws a short burst of high current. If the fuel gauge IC is still calibrated to the old degraded cell's curve, it reads 25% while the actual cell voltage has already sagged below the shutdown threshold — roughly 3.2V under load. The phone cuts out to protect the hardware, not because the replacement cell is defective. One full discharge-charge cycle at standard current corrects the mismatch between the stored curve and the new cell's actual voltage profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the cell voltage dropped below approximately 2.5V per cell, the BMS enters a lockout state and blocks normal charge current to prevent damage. The phone shows nothing — no charging indicator, no boot. Connect the phone to a wall charger and leave it undisturbed for 20–30 minutes; most BMS controllers accept a trickle current at this voltage and will exit lockout once the cell reaches roughly 3.0V. If the indicator still does not appear after 45 minutes, try a different cable and confirm the charger delivers at least 5V\/1A before assuming the cell is at fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392111706202,"sku":"BWCS-AVS590SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392111738970,"sku":"BWCS-AVS590SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392111771738,"sku":"BWCS-AVS590SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVS590SL-1.webp?v=1779143848","url":"https:\/\/batteryweb.com\/products\/archos-59-titanium-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
