Mascom International stocks the Amaya BL-25BT Replacement Battery at KSh 520, a brand new and sealed rechargeable lithium-ion cell holding 2500mAh at a rated 3.7V, for 9.25Wh of stored energy. The Amaya BL-25BT Replacement Battery has a limited charge voltage of 4.2V, and the code BL-25BT is printed clearly on its label. That code is the whole buying decision: it must match the battery coming out of your phone letter for letter. Pick one up at our first-floor shop in the Old Mutual Building, Kimathi Street, Nairobi CBD, or order it to your door.
Designed for owners of feature phones and budget handsets with a removable back cover, the Amaya BL-25BT Replacement Battery revives a phone whose old cell no longer lasts. Shop owners in Gikomba, M-Pesa agents in Kisumu and boda boda riders in Nakuru often keep a basic phone as their main business line because it is tough and cheap to run. When the battery fades, calls drop mid-sentence and the phone dies before closing time. A fresh cell with the right code fixes that in minutes, with no technician, no tools and no need to buy a new handset.
Where most Nairobi electronics shops hand over whatever loose cell looks closest, Mascom International checks the code against your phone before selling the Amaya BL-25BT Replacement Battery. That matters here, because Amaya also makes a BL-25Bi with the same capacity and voltage but a different code and contact layout. At Mascom International, we're seeing buyers return to the shop after kiosks sold them the wrong one. Bring your old battery, send a clear photo of its label on WhatsApp, or order the Amaya BL-25BT Replacement Battery for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the Amaya BL-25BT Replacement Battery
What is the Amaya BL-25BT Replacement Battery price in Kenya?
The Amaya BL-25BT Replacement Battery sells for KSh 520, brand new and sealed, at Mascom International on Kimathi Street, Nairobi. The price includes a 6-month warranty on manufacturing defects and pay-on-arrival delivery to every county. The Amaya BL-25Bi costs KSh 320 and lists the same 2500mAh and 3.7V ratings, but it is built for different phones. The KSh 200 difference reflects a different part, not extra capacity, so let your phone's code decide.
How do I confirm my phone takes the Amaya BL-25BT Replacement Battery?
Your phone takes the Amaya BL-25BT Replacement Battery only if its current battery reads BL-25BT exactly. Switch the phone off, slide off the back cover and lift the old cell out. The code is printed on its front label, and many phones repeat it on a sticker inside the battery bay. Compare every letter, because BT and Bi are easy to confuse. If the label is faded, our staff at Mascom International can identify the right battery from the phone itself.
Can I use the cheaper Amaya BL-25Bi instead of the Amaya BL-25BT Replacement Battery?
No, the Amaya BL-25Bi is not a substitute for the Amaya BL-25BT Replacement Battery, even though both list 2500mAh, 3.7V and 9.25Wh. The two codes are made for different handsets, and the contact layout differs, so the wrong cell may not connect to the phone's pins or sit flat under the cover. Saving KSh 200 on the BL-25Bi only makes sense if your old battery says BL-25Bi. Match the code and the phone works as it did when new.
How should I store a spare Amaya BL-25BT Replacement Battery in Kenyan heat and humidity?
Store a spare Amaya BL-25BT Replacement Battery partly charged, in a cool, dry drawer away from direct sun. Hot afternoons in Garissa or Kisumu and the damp coastal air in Mombasa both shorten the life of lithium-ion cells left in the open. Keep the spare in a small pouch so coins and keys cannot touch the contacts. Charging it fully every few weeks keeps it ready for KPLC outages, when a second charged battery saves a trip to a charging kiosk.
Why buy the Amaya BL-25BT Replacement Battery from Mascom International instead of a street kiosk?
Mascom International sells the Amaya BL-25BT Replacement Battery sealed, with its ratings printed honestly and a 6-month warranty behind it. Many kiosks around Moi Avenue and River Road sell unbranded cells stamped "original" with no way to verify capacity or age. Customers across Nairobi tell us those cells swell or fade within weeks. Here you also get a free code check before paying, a receipt, and a physical shop in Nairobi CBD to return to if a defect appears.
What do 9.25Wh and 4.2V mean on the Amaya BL-25BT Replacement Battery?
On the Amaya BL-25BT Replacement Battery, 9.25Wh is the total energy stored, and 4.2V is the highest voltage the cell reaches when fully charged. Watt-hours come from multiplying capacity by voltage: 2.5 amp-hours times 3.7V gives 9.25Wh. The 3.7V figure is the rated voltage the phone runs on during normal use. The 4.2V limit is handled by your phone's charging circuit, so you simply plug the handset into its usual charger.
Who should buy the Amaya BL-25BT Replacement Battery, and who should skip it?
The Amaya BL-25BT Replacement Battery is for anyone whose phone uses a BL-25BT cell that now drains quickly, runs hot or has started to bulge. Small traders, security guards on night shifts and grandparents with a simple keypad phone all benefit. Skip it if your battery reads BL-25Bi, BL-24EI or any other code; buy that exact match instead. It is also the wrong fix for a smartphone with a sealed battery, which needs a repair technician.
How do I know my old battery needs replacing before buying the Amaya BL-25BT Replacement Battery?
Your old cell needs replacing when the phone dies well before evening, switches off while still showing charge, or gets warm during simple calls. A bulging battery that lifts the back cover is the most urgent sign; stop using it immediately. Swapping in the Amaya BL-25BT Replacement Battery solves all of these when the battery is the worn part. If a new cell still drains fast, the charging port or phone board may be at fault instead.
Technical Specifications
Core Function and Power Ratings
- Rechargeable lithium-ion cell — the same battery chemistry found in modern phones, charged hundreds of times over its working life.
- 2500mAh capacity — milliamp-hours describe stored charge; this figure tells you how much the cell holds compared with your worn original.
- 3.7V rated voltage — the steady voltage the phone draws during normal use, matching what a BL-25BT handset is designed to receive.
- 9.25Wh stored energy — capacity multiplied by voltage, a single number that airlines and shippers use to classify a battery's size.
- 4.2V limited charge voltage — the full-charge ceiling for the cell, controlled automatically by the phone so overcharging is avoided.
Compatibility and the BL-25BT Code
- Code BL-25BT on the label — the only reliable way to confirm fit; compare it letter by letter with the battery you are replacing.
- Different from the BL-25Bi — identical headline ratings, but a separate code made for other phones with a different contact layout.
- Matching code means matching shape and terminals — the cell drops into the bay and its contacts meet the phone's pins correctly.
- For removable-battery phones — feature phones and budget handsets where the back cover comes off by hand and the cell lifts out.
- No phone list needed — the printed code on your old battery is more accurate than any model list, so rely on it.
Build and Label
- Brand new and sealed — supplied unused in its original packaging, so you are the first person to charge and use the cell.
- Printed rating label — capacity, rated voltage, watt-hours and charge limit are shown on the cell for easy checking against your old one.
- Slim flat body — a rectangular pack that fits flush under the back cover without forcing the case closed.
- Exposed contact terminals — the metal strip that meets the phone's pins; keep it clean and away from metal objects.
- Made by Amaya — the Chinese accessories brand behind chargers, cables and power banks already sold at Mascom International.
Charging and Daily Use
- Charges in the handset — use the phone's own charger; the battery needs no cradle or separate charging dock.
- Full first charge recommended — a new cell can take a few cycles before the charge indicator reads steadily.
- Avoid heat while charging — a phone left on a sunny dashboard or windowsill ages its battery faster.
- Partial charges are fine — lithium-ion cells do not need to be run flat before plugging in again.
- Replace if it swells — a bulging cell is damaged; stop using it, and never puncture or burn it.
Inclusions and After-Sales
- One BL-25BT battery — the sealed cell is the only item in the pack, ready to fit straight away.
- No charger or cable — the phone's existing charger powers it, so nothing extra is required for daily use.
- 6-month Mascom warranty — covers manufacturing defects under normal use, handled at our Nairobi CBD service desk.
- Code check before purchase — staff confirm your phone takes a BL-25BT before any money changes hands.
- Recycling advice — ask in store where to drop your old cell instead of throwing it in a fire or rubbish pit.
Package Contents
Inside the pack you get the Amaya BL-25BT Replacement Battery and nothing else, sealed and unused. No charger or USB cable is included because the cell charges through your phone with the handset's existing charger. If that charger is damaged, Mascom International carries replacement chargers in store, and bringing the phone helps us match the right plug. Keep the packaging until you have fitted the battery and confirmed the phone powers on, in case you need to raise a warranty claim.
Warranty
The Amaya BL-25BT Replacement Battery carries a 6-month warranty from Mascom International covering manufacturing defects under normal use. A cell that will not charge or holds far less than it should because of a factory fault can be brought to our Nairobi CBD service desk, where claims are assessed.
