Capacity is 1900mAh (7.22Wh), matching the OEM specification. It fits any unit carrying part number 0B200-02170000 or B11P1602.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZB500KL, X00A, X00ADA compatibility:\u003c\/strong\u003e\n    All three model codes refer to the same ZenFone Go 5.0 hardware platform. They share an identical connector pinout, battery bay dimensions (64.28 × 56.64 × 5.10mm), and the same BMS handshake with the charge IC — so one cell covers the full production run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a ZB500KL unit. The BMS accepted charge current without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold before the cell reached damaging depth.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge-to-charge cycle before normal use. The fuel gauge IC is still calibrated to your old cell's discharge curve. One full cycle lets it remap against the new cell so percentage readings track accurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ZenFone Go 5.0 shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZenFone Go 5.0 uses a coulomb counter fuel gauge that was trained on the original cell's voltage-versus-capacity curve. A new cell has a slightly different curve — the voltage drop at low charge is steeper than the old degraded cell the gauge expects. When the modem transmits or the screen lights up, current draw spikes and the cell voltage sags below the shutdown threshold even though the gauge still reads 20–30%. Running one full discharge cycle down to automatic shutdown, then charging uninterrupted to 100%, rewrites the gauge's reference curve and eliminates the false-floor cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone does not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the replacement cell dropped below approximately 2.5V per cell before installation, the BMS has entered lockout mode to prevent damage — and the phone will show nothing when you press the power button. Connect the phone to a wall charger (not a PC USB port) and leave it for 15–20 minutes without pressing anything. The charge IC delivers a low-current pre-charge trickle that brings the cell above the BMS re-enable threshold, after which normal charging resumes. If the charging indicator does not appear within 30 minutes, check that the battery connector is fully seated at 3.8V rest voltage before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392028311642,"sku":"BWCS-AUB500SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392028344410,"sku":"BWCS-AUB500SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392028377178,"sku":"BWCS-AUB500SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUB500SL-1.webp?v=1779143029","url":"https:\/\/batteryweb.com\/products\/asus-zenfone-go-50-replacement-battery-38v-1900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
