SANISI V6W33 15V 54Wh 4‑Cell Laptop Battery for Dell

SANISI V6W33 is a brand-new 15V 54Wh 4-cell replacement battery built to restore portable power to compatible Dell Inspiron, Latitude and Vostro laptop models.

If your Dell laptop no longer holds a charge or dies quickly on battery power, the SANISI V6W33 offers a direct-fit OEM-quality replacement option. This battery matches the original 4-cell layout and electrical specifications (15V, 54Wh) used in many 13"–16" Inspiron, Latitude and Vostro machines. Before ordering, confirm your laptop’s battery shape and model number to pick the correct 3-cell or 4-cell variant for a perfect fit.

How do I know this battery is compatible with my Dell laptop?

Compatibility depends on both model family and the physical battery type installed in your machine. The V6W33 replaces Dell part numbers such as V6W33, TN70C, G91J0 and others listed by SANISI and fits many Inspiron, Latitude and Vostro series models. Always open the laptop’s back cover to compare the original battery’s size and connector to ensure you choose the 4-cell 54Wh option rather than a shorter 3-cell or longer 64Wh variant.

• Fits many Inspiron 13/14/15/16, Latitude 3320–3530 and Vostro 13/14/15/16 models.
• Replaces listed alternate part numbers like V6W33, G91J0, TN70C variants.
• Confirm physical length: 3-cell (short), 4-cell (long) — check your original battery.

What performance and safety features does this SANISI battery include?

The V6W33 is manufactured new and includes multi-layer protection circuits to guard against overcharge, over-discharge, short circuit and high temperature events. SANISI specifies the battery for up to approximately 500 recharge cycles under typical use, and the pack is built to match OEM voltage and capacity for stable operation. While it restores battery runtime, actual lifespan and runtime vary with usage patterns and charging habits.

• Rated 15V and 54Wh — designed to match original laptop power requirements.
• Protection: overcharge/discharge, over-temperature and short-circuit safeguards.
• Manufactured new; estimated up to 500 recharge cycles under normal conditions.

How do I install the replacement battery and what comes in the package?

Installation is straightforward but requires a small screwdriver and a static-free work area. Power down the laptop, remove the back cover, unplug the old battery connector and unscrew the mounting screws before swapping in the SANISI unit. The package includes a single brand-new OEM-style battery and SANISI offers customer support if you encounter fitment or installation questions.

• Package contains 1 x brand-new SANISI OEM-style 4-cell battery.
• No tools provided — use proper screwdriver and static precautions.
• Support: replacement within 12 months and 30-day full refund policy.

Who is this for: The SANISI V6W33 4-cell battery is intended for Dell owners who need a reliable, like-for-like replacement battery for Inspiron, Latitude and Vostro laptops that originally used a 4-cell 54Wh pack. It suits technicians, students and professionals seeking a cost-effective OEM-compatible swap to restore unplugged runtime—provided they confirm model compatibility and battery size before purchase.
