It replaces OEM part numbers T1G6P, 0449TX, PRW6G, 312-8479, ONTG4J, and CN-0449TX. At 29.97Wh and 5.33mm thin, it fits the slim chassis without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVostro V13 family compatibility:\u003c\/strong\u003e\n    The V13, V130, V13Z, and V1300 all share the same 11.1V battery rail, flat Li-Polymer form factor, and connector pinout. Dell used multiple OEM part numbers across production runs, but the electrical spec and physical fitment are identical across all four models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Vostro V130. The BMS communicated correctly with the Dell EC, charge current tapered normally at top-of-charge, and the protection circuit tripped as expected at low-cell-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after installation:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells in Dell notebooks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Vostro V13 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vostro V13 uses a fuel gauge IC that builds a discharge model against the original cell's internal resistance profile. A new cell has different resistance, so the gauge miscalculates the voltage cliff — the point where cell voltage drops sharply under combined CPU and display load. The system reads this drop as critically low and forces shutdown even though charge remains. Running two or three full discharge-to-hibernate then full-charge cycles allows the fuel gauge IC to re-map the new cell's profile and eliminates the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting 0% or \"unknown battery\" immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dell BIOS reads battery identity and state-of-health from EEPROM data embedded in the battery's BMS chip. When a replacement cell is first connected, the BIOS has not yet validated that EEPROM data and may report 0% or flag the battery as unknown. This is not a fault with the cell. Power the laptop off completely, reseat the battery connector firmly, then boot and allow the system to sit at the desktop for five minutes while the EC polls the BMS. If the warning persists after one full charge cycle, check that the connector is fully engaged — even one pin out of contact causes this on the V13's slim board layout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409787420762,"sku":"BWCS-DEV130NB-1","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409787453530,"sku":"BWCS-DEV130NB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409787486298,"sku":"BWCS-DEV130NB-3","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEV130NB-1.webp?v=1779580887","url":"https:\/\/batteryweb.com\/products\/dell-vostro-v13-replacement-battery-111v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
