TKV2V (also listed as 0TKV2V) is a 6-cell lithium-ion laptop battery primarily for Dell Inspiron models, including the N4020 series. It is a common OEM/replacement part number for these older Dell notebooks.
The TKV2V is a rechargeable Li-ion battery pack designed as a direct replacement for the original battery in compatible Dell Inspiron laptops. It provides portable power, is typically black, and features standard laptop battery form factor for easy installation (user-replaceable in most models). Replacement versions from third-party brands (e.g., Denaq, WISTAR) are widely available and claim compatibility with original OEM specifications. Some higher-capacity variants exist, but the standard is ~48 Wh.
For the most accurate match, check the part number printed on your current battery or the laptop's service tag/manual. Specs above are compiled from multiple battery retailers and listings for the TKV2V / Dell Inspiron N4020.
