The Dell Inspiron N4020 Laptop Battery is available at Mascom International for KSh 3,200, a brand new 11.1V, 4400mAh replacement battery with six lithium-ion cells. It slots into the back edge of the 14-inch Inspiron N4020, N4030, N4030D, 14V and 14VR, a family of everyday home and student laptops. Collect it at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, where the team will check the fit at the counter if you bring the laptop. You can also order it for pay-on-arrival delivery anywhere in the country, after confirming the part code with us on WhatsApp.
Built for university students, teachers, small-business owners and families keeping an older Inspiron in daily use, the Dell Inspiron N4020 Laptop Battery answers a simple need. Many of these laptops now die the moment the charger cable slips out, which makes them useless in a lecture hall with too few sockets or a hostel room during a blackout. A student at Kenyatta or Moi University can lose an assignment draft that way. Fitting a fresh Dell Inspiron N4020 Laptop Battery brings back cordless use, so the laptop moves from desk to class to the kitchen table without a cable trailing behind.
Where most Nairobi electronics shops guess at which battery fits, Mascom International matches the part code on your old pack before you pay. Buyers throughout Kenya report that a working battery is what turns an old Inspiron from a desk-bound machine back into a usable laptop for typing, eCitizen forms and M-Pesa statements. The Dell Inspiron N4020 Laptop Battery comes with a 6-month warranty and pay-on-arrival delivery to all 47 counties. Message the code from your old battery on WhatsApp, or walk into the Kimathi Street store, to confirm the Dell Inspiron N4020 Laptop Battery fits.
Common Questions About the Dell Inspiron N4020 Laptop Battery
How much does the Dell Inspiron N4020 Laptop Battery cost in Kenya?
The Dell Inspiron N4020 Laptop Battery costs KSh 3,200 as a replacement unit at Mascom International, Kimathi Street, Nairobi CBD. That figure includes the 6-month warranty against manufacturing defects but no charger and no fitting labour. Fitting is simple, since the pack slides into the rear of the laptop and locks with a latch. Delivery is pay-on-arrival, so you only pay once the battery is in your hands. It sits KSh 200 above the Dell Latitude E6400 Laptop Battery, which suits a different Dell range.
Which Inspiron models does the Dell Inspiron N4020 Laptop Battery fit?
The Dell Inspiron N4020 Laptop Battery fits the Inspiron N4020, N4030, N4030D, 14V and 14VR, all 14-inch models that share one battery shape and connector. It does not fit the Inspiron 14R with model number N4010, which looks similar but takes a different pack, often coded J1KND. Customers often mix the two up, so check carefully. Look for the model number on the sticker under the laptop, not only the name near the keyboard, before you order.
Is the Dell Inspiron N4020 Laptop Battery the same as the Dell Latitude E6400 Laptop Battery, since both are 11.1V 4400mAh?
No, the Dell Inspiron N4020 Laptop Battery and the Dell Latitude E6400 Laptop Battery share the same 11.1V and 4400mAh rating but are not interchangeable. The Inspiron pack mounts at the rear of a consumer laptop, while the Latitude pack clips into the underside of a business laptop, and their shapes and connectors differ. Mascom International sells the Inspiron battery at KSh 3,200 and the Latitude battery at KSh 3,000. Matching voltage and capacity never guarantees a fit, so always buy by laptop model or part code.
What part codes on my old battery match the Dell Inspiron N4020 Laptop Battery?
The Dell Inspiron N4020 Laptop Battery matches packs labelled TKV2V, W4FYY, FMHC1, YM5H6, M4RNN, 4J99J, KG9KY, PD3D2, YPY0T or 312-1231. Slide out the old battery and read the label on its underside to find the code. If the label has worn away, the model sticker under the laptop works just as well. Send a photo of either one to +254 708 852 521 on WhatsApp and our team confirms the match, saving a buyer in Kisii or Kakamega a wasted delivery.
Is the Dell Inspiron N4020 Laptop Battery a good fix for studying through power cuts?
Yes, the Dell Inspiron N4020 Laptop Battery lets the laptop keep running on stored power when KPLC supply cuts out in a hostel or at home. Charge it fully whenever mains power is on, then save your work often during an outage. Dim the screen and close the browser tabs you are not using to stretch the charge. In hot rooms, or during Mombasa's humid months, use the laptop on a hard surface so the vents stay clear, since heat ages battery cells faster.
Who should buy the Dell Inspiron N4020 Laptop Battery and who should skip it?
Buy the Dell Inspiron N4020 Laptop Battery if your N4020, N4030, 14V or 14VR still boots, types and browses well but cannot work away from the socket. Students, home users and small shops keeping a sound older laptop running get the clearest value. Skip it if you own an Inspiron 14R N4010, which needs a different battery, or if the laptop has a failing screen or charging port, since a battery will not cure those faults. Buyers needing a fast machine for heavy software are better served by a newer laptop altogether.
Can the Dell Inspiron N4020 Laptop Battery make an older Inspiron useful again?
The Dell Inspiron N4020 Laptop Battery fixes unplugged runtime only; it does not make the laptop faster. If the laptop already handles your documents, email and browsing comfortably, the battery is the missing piece that turns it portable again. If it feels slow, the battery will not change that, because speed depends on the processor, memory and drive. Some owners pair a battery with a storage or memory upgrade from a technician they trust. Judge the laptop's speed first, then decide whether KSh 3,200 on a battery is the right spend.
How do I fit and look after the Dell Inspiron N4020 Laptop Battery?
The Dell Inspiron N4020 Laptop Battery slides into the rear edge of the laptop and locks with the battery latches, with no tools needed. Shut down, unplug the charger, close the lid, turn the laptop over, slide the release latch and pull the old pack out. Push the new one in until the latch clicks. Charge it fully before using it cordless for long. Avoid storing it completely flat for weeks, and keep it out of hot cars and sunny window ledges.
Technical Specifications
Cell and Capacity
- Rated at 11.1V nominal — matches the voltage this Inspiron family expects, so the laptop charges the pack normally.
- 4400mAh capacity — about 49 watt-hours of stored energy for typing, browsing and video lessons away from a socket.
- Six-cell lithium-ion layout — the standard format for this Inspiron battery family, balancing weight and runtime.
- Lithium-ion chemistry — no memory effect, so short top-ups between classes do no harm to capacity.
- Fresh cells — never used or reconditioned, so the pack starts at its full rated capacity.
Compatibility and Model Matching
- Fits the Inspiron N4020 — the 14-inch home and student laptop this battery is named after.
- Fits the Inspiron N4030 and N4030D — closely related models that share the same bay and connector.
- Fits the Inspiron 14V and 14VR — the retail names used for laptops in this same family.
- Not for the Inspiron 14R N4010 — that model takes a different battery, often coded J1KND.
- Model unclear — send a photo of the sticker under the laptop on WhatsApp and we confirm the right battery.
Part Codes to Match
- Matches TKV2V and W4FYY — widely seen codes printed on packs for this Inspiron family.
- Matches FMHC1, YM5H6 and M4RNN — further codes for the same six-cell battery.
- Matches 4J99J, KG9KY, PD3D2 and YPY0T — additional codes from different production runs.
- Matches 312-1231 — the longer service-number format found on some labels.
- Code faded or missing — a photo of the laptop's base on WhatsApp lets us confirm the match instead.
Build and Safety
- Rear-mounted design — the pack slides into the back edge of the laptop and locks with latches, no screws involved.
- Black casing — matches the dark underside of these Inspiron models.
- Built-in protection circuit — guards the cells against overcharge, deep discharge and short circuits.
- Charge level shown in Windows — the battery reports remaining charge so you know when to plug in.
- Firm latch fit — the pack stays put when the laptop travels in a backpack between home and class.
Charging and Care
- Charges through the laptop's existing Dell adapter — no separate charger is required.
- Full first charge — lets the Windows gauge learn the new pack's capacity for accurate readings.
- Partial charge for storage — cells age slowest when kept neither full nor empty during long breaks such as school holidays.
- Keep away from strong heat — car interiors and sunny ledges shorten lithium-ion life.
- Hard, flat surfaces during use — beds and cushions block vents and raise the battery's temperature.
