HP ProBook 4520s Laptop Battery is in stock at Mascom International for KSh 3,000, a brand new 10.8V 4400mAh replacement pack for the ProBook 4520s, ProBook 4320s and HP 620. The HP ProBook 4520s Laptop Battery is a compatible replacement built to the PH06 format that HP used across this family of older business laptops. You can collect it from our shop on the first floor of Old Mutual Building, Kimathi Street, in Nairobi CBD. Bring your laptop along and our team will check the fit at the counter before you pay.
Built for accountants, small business owners, university students and NGO field staff who still rely on an older ProBook, this battery solves a common problem. A worn-out pack lasts minutes off the wall, or the laptop shuts down the moment you pull the charger. During a KPLC power cut, that means lost work and a dead machine. The HP ProBook 4520s Laptop Battery restores unplugged running time, so you can finish a KRA return, close a spreadsheet or keep a Zoom call going until power returns. It also lets you move the laptop between desks or rooms without losing your session.
Where most Nairobi electronics shops sell unlabelled batteries from a box behind the counter, Mascom International matches the pack to your laptop's model sticker or the code on your old battery first. Send a photo of either on WhatsApp and we will confirm the HP ProBook 4520s Laptop Battery fits before you order. Customers across Nairobi tell us a fresh battery kept an aging ProBook in daily service for far less than the cost of another laptop. Order the HP ProBook 4520s Laptop Battery for pay-on-arrival delivery, or walk in and have the fit checked.
Common Questions About the HP ProBook 4520s Laptop Battery
How much is the HP ProBook 4520s Laptop Battery in Kenya?
The HP ProBook 4520s Laptop Battery costs KSh 3,000, brand new, at Mascom International in Nairobi CBD. That price covers one 10.8V 4400mAh replacement pack and a 6-month warranty against manufacturing defects. It does not include a charger, since your existing HP adapter powers it. You can pay on arrival anywhere in Kenya, or pay at the counter in Old Mutual Building after our team checks the fit on your laptop. The ProBook 4530s battery in the same batch also costs KSh 3,000.
Which laptops does the HP ProBook 4520s Laptop Battery fit?
The HP ProBook 4520s Laptop Battery fits laptops that take HP's PH06 battery, including the ProBook 4520s, 4320s and HP 620. The same pack is listed for the ProBook 4325s, 4420s, 4421s, 4425s and 4525s, plus the HP 420, 425 and 625 and the Compaq 320, 321, 420, 421, 620 and 621. The quickest check is the code on your old battery: PH06, 593572-001 or BQ350AA. Send that code or your model sticker to us on WhatsApp before ordering.
How does the HP ProBook 4520s Laptop Battery compare with the HP ProBook 4530s Laptop Battery?
Both packs cost KSh 3,000 at Mascom International, but they fit different laptops and cannot be swapped. The HP ProBook 4520s Laptop Battery uses the older PH06 shape and connector for the 4520s, 4320s and HP 620. The 4530s battery uses the later PR06 shape for the ProBook 4530s and 4535s. Choose by the laptop on your desk, not by the price. If your model number starts with 452, 432 or 442, the 4520s pack is the one to buy.
How should I charge and care for the HP ProBook 4520s Laptop Battery in Kenya's heat and power cuts?
The HP ProBook 4520s Laptop Battery lasts longest when kept away from heat and charged regularly. Avoid leaving the laptop in a parked car in Mombasa or Garissa sun, and keep the vents clear of dust so the pack does not cook under load. During long KPLC outages, drain it, then recharge fully once power returns. If the laptop stays plugged in all week, run it on battery for an hour now and then. Store a spare pack at roughly half charge.
How long does the HP ProBook 4520s Laptop Battery run on one charge?
Running time from the HP ProBook 4520s Laptop Battery depends mostly on what the laptop is doing and how bright the screen is. Its 4400mAh capacity at 10.8V works out to about 47Wh, the standard rating for this battery family. Typing documents, email and light browsing draw far less power than video calls or long spreadsheets. Older hard drives and dusty fans also raise power use. Lower the screen brightness and close idle browser tabs to stretch each charge further.
Can I fit the HP ProBook 4520s Laptop Battery myself?
Yes, the HP ProBook 4520s Laptop Battery is an external pack that slides into the bay underneath the laptop, so no screwdriver is needed. Shut the laptop down, unplug the charger, slide the release latch and lift out the old battery. Drop the new pack into the bay until it clicks. Charge it fully before the first long session off mains power. If you prefer, bring the laptop to our Kimathi Street shop and our team will check the fit with you.
Who should buy the HP ProBook 4520s Laptop Battery, and who should skip it?
Buy the HP ProBook 4520s Laptop Battery if you own a ProBook 4520s, 4320s, 4420s or HP 620 that still runs well but dies off the charger. It suits offices, schools and cyber cafes keeping older machines working. Skip it if your laptop is a ProBook 4530s or 4535s, because that model needs the PR06 pack instead. Also skip it if the laptop itself is failing; at that point a used EliteBook or ThinkPad from Mascom International is the better spend.
Is it worth replacing the battery on an older HP ProBook 4520s in Kenya?
A new battery is worth it when the rest of the ProBook 4520s still works properly. For KSh 3,000, the HP ProBook 4520s Laptop Battery turns a desk-bound machine back into one you can carry to a meeting in Westlands or a lecture at Kenyatta University. Adding an SSD at the same time makes the laptop feel quicker too. If the screen, hinges or motherboard are failing, put the money toward a replacement laptop instead.
Technical Specifications
Cell and Capacity
- 10.8V nominal voltage — matches what the ProBook 4520s and its siblings expect, so the laptop charges and reads the pack normally.
- 4400mAh rated capacity — the standard size for this battery family, giving the full running time the laptop was designed around.
- About 47Wh of stored energy, worked out from 10.8V and 4400mAh — the figure airlines and couriers ask about for lithium batteries.
- Lithium-ion chemistry — light for its capacity and free of the memory effect, so topping up between meetings does no harm.
- Charges through your existing HP laptop adapter — the laptop controls charging, so no separate charger or dock is needed.
- Brand new cells with no prior charge cycles — every bit of rated capacity is available from the first full charge.
Compatibility and Model Matching
- Built to HP's PH06 battery format — the code printed on many original packs for this family, which makes matching simple.
- Matches HP part numbers 593572-001, 587706-751 and BQ350AA — check the label on your old battery for any of these codes.
- Fits the ProBook 4320s, 4325s, 4420s, 4421s, 4425s, 4520s and 4525s — the core business laptops this pack was designed for.
- Also listed for the HP 420, 425, 620 and 625, and the Compaq 320, 321, 420, 421, 620 and 621.
- Does not fit the later ProBook 4530s or 4535s — those use the PR06 shape, sold separately at Mascom International.
- Unsure of your model? The sticker under the laptop names it; send a photo on WhatsApp and we confirm the fit.
Build and Safety
- External slide-in pack — locks into the bay under the laptop with the existing release latch, with no screws or tools.
- Shaped to sit flush with the laptop body — no bulge at the back, so it fits a standard laptop bag or sleeve.
- Built-in control board reports charge level to Windows — the battery icon shows remaining charge and time, as with the original.
- Contacts sit in a recessed connector — protects the terminals from dust, which matters on dusty roads and in busy offices.
- Avoid heat above normal room temperature — leaving the laptop in a hot car shortens the life of any lithium battery.
- Recycle the old pack responsibly — bring it to our Kimathi Street shop rather than dropping it in household rubbish.
Inclusions
- One brand new 10.8V 4400mAh replacement battery for the ProBook 4520s family, ready to slide into the bay.
- No charger or power cord in the package — your existing HP adapter charges the pack through the laptop.
- HP laptop adapters are sold separately at Mascom International if your current charger is worn or missing.
- Fit check available at our Nairobi CBD counter — bring your laptop and confirm the pack locks in before paying.
- Covered by a 6-month warranty against manufacturing defects, handled at our service desk in Nairobi CBD.
