Amaya BL-25Bi Replacement Battery | 2500mAh Capacity | 3.7V Standard Voltage | 9.25Wh Rated Energy
A fresh cell for kabambe handsets that need to keep going from the morning matatu to the evening market.
Condition: New
Note: price and availability are subject to change without prior notice
Amaya BL-25Bi Replacement Battery is available at Mascom International for KSh 320, a brand new and sealed 2500mAh lithium-ion cell rated at 3.7V standard and 9.25Wh. The Amaya BL-25Bi Replacement Battery comes on Amaya's orange blister card marked "High Capacity Battery", with the code BL-25Bi printed on the cell so you can match it against the battery already in your phone. Its limited charge voltage is 4.2V, the usual ceiling for this type of cell. You can collect one at our shop in the Old Mutual Building on Kimathi Street, Nairobi CBD, or order it for delivery.
Built for people across Kenya who rely on a feature phone or budget handset with a back cover, the Amaya BL-25Bi Replacement Battery brings back the long standby time that made the phone useful in the first place. A mama mboga taking orders by call, a boda boda rider waiting for the next customer, or an M-Pesa agent running a second line all feel it when an old battery dies by lunchtime. Swapping in a new cell with the same code takes a minute, needs no tools, and costs far less than buying another phone.
Unlike the repair kiosks along Moi Avenue and River Road that sell unbranded cells labelled "original", Mascom International sells the Amaya BL-25Bi Replacement Battery sealed, with the specifications printed honestly on the pack. Customers across Nairobi tell us the hardest part is finding the right code, so bring your old battery or a photo of its label and we will check it against the Amaya BL-25Bi Replacement Battery before you pay. Walk into the shop on Kimathi Street, or order on WhatsApp for pay-on-arrival delivery to any county in Kenya.
Common Questions About the Amaya BL-25Bi Replacement Battery
How much is the Amaya BL-25Bi Replacement Battery in Kenya?
The Amaya BL-25Bi Replacement Battery costs KSh 320 brand new and sealed at Mascom International in Nairobi CBD. That price covers the 2500mAh cell on its blister card, Mascom's 6-month warranty against manufacturing defects, and pay-on-arrival delivery across Kenya. Amaya also makes the BL-25BT at KSh 520, which shares the same 2500mAh and 3.7V figures but carries a different code, so the KSh 200 gap is not an upgrade. Buy whichever code matches your old battery.
Will the Amaya BL-25Bi Replacement Battery fit my phone?
The Amaya BL-25Bi Replacement Battery fits only phones built for a BL-25Bi battery, so match the code before you buy. Remove your back cover and read the code printed on your old battery and on the label inside the phone. Same code means same size, same contact layout and same voltage. A battery that looks similar but carries another code may not seat properly or charge. If the label has worn off, bring the phone to Mascom International and we will check it for you.
How does the Amaya BL-25Bi Replacement Battery compare with the Amaya BL-25BT?
The Amaya BL-25Bi Replacement Battery and the Amaya BL-25BT share the same 2500mAh capacity, 3.7V rating and 9.25Wh energy figure, but they are not interchangeable. Each carries its own code and is built for different phones, with contacts arranged to suit those handsets. The BL-25Bi sells at KSh 320 and the BL-25BT at KSh 520 at Mascom International. Choose strictly by the code on your old battery, never by price or capacity, and the cell will sit and charge as it should.
How should I charge a new Amaya BL-25Bi Replacement Battery the first time?
Charge the Amaya BL-25Bi Replacement Battery fully before first use, using your phone's own charger. A new lithium-ion cell may take a few charge cycles to settle, so the battery indicator can look uneven during the first days. That is normal and clears with regular use. The cell's limited charge voltage is 4.2V, which your phone's charging circuit already controls, so no special charger is needed. After the first cycles, charge whenever it is convenient rather than running the phone flat every time.
Is the Amaya BL-25Bi Replacement Battery a good choice during KPLC power cuts and Kenyan heat?
A fresh Amaya BL-25Bi Replacement Battery restores the full 2500mAh rating to a worn handset, which matters when KPLC outages stop you charging for hours. Many families upcountry keep a feature phone on Safaricom or Airtel Kenya as a backup line for exactly these days. Heat is the main enemy of lithium-ion cells, so never leave the phone charging in direct sun on a matatu dashboard or a hot window ledge in Mombasa. A shaded pocket or bag helps the cell last longer.
What safety rules apply to the Amaya BL-25Bi Replacement Battery and my old cell?
Replace any swollen battery at once, because a puffed cell can push the back cover off and damage the phone. Never puncture, crush or burn a lithium-ion battery, including the Amaya BL-25Bi Replacement Battery. When you swap in the new cell, do not throw the old one in a fire or the household rubbish pit. Take it to an e-waste collection point instead, where used cells are recycled safely. Keep loose batteries away from coins and keys, which can short the contacts.
Who should buy the Amaya BL-25Bi Replacement Battery, and who should skip it?
Buy the Amaya BL-25Bi Replacement Battery if your phone uses a BL-25Bi cell and the old one drains fast, swells, or shuts the phone off early. It suits M-Pesa agents, shopkeepers and parents keeping a basic phone running for an elderly relative. Skip it if your code reads BL-25BT, BL-24EI or anything else, and buy that exact code instead. Skip it too if your smartphone has a sealed battery, because that needs a technician rather than a removable cell.
Is the Amaya BL-25Bi Replacement Battery worth buying instead of a new phone?
For most owners, yes: the Amaya BL-25Bi Replacement Battery costs KSh 320, a small fraction of a new feature phone. When the battery is the only part that has worn out, a new cell restores standby time while you keep your contacts, SIM setup and familiar keypad. Buyers throughout Kenya report that a fresh battery makes a tired kabambe usable for calls, SMS and M-Pesa again. If the screen, keypad or charging port is also failing, a new handset may make more sense.
Technical Specifications
Core Function and Electrical Ratings
- Lithium-ion chemistry — the rechargeable cell type used in modern phones, holding charge well between uses without the memory effect of older batteries.
- 2500mAh rated capacity — milliamp-hours measure how much charge the cell stores; a higher figure means longer use between charges in the same phone.
- 3.7V standard voltage — the nominal voltage your phone expects from a cell of this code, so the handset runs exactly as designed.
- 9.25Wh energy rating — watt-hours combine capacity and voltage (2500mAh multiplied by 3.7V), giving one direct figure for the total energy stored.
- 4.2V limited charge voltage — the highest voltage the cell should reach while charging; your phone's charging circuit stops it there automatically.
Compatibility and Code Matching
- Code BL-25Bi — printed on the cell; it must match the code on your old battery and the label inside your phone exactly.
- Same code means same size, contacts and voltage — the battery sits flat in the bay and its terminals line up with the phone's pins.
- Not interchangeable with the BL-25BT — that cell shares the 2500mAh and 3.7V figures but is built for different handsets and contacts.
- For phones with a removable back cover — made for feature phones and budget phones where the battery lifts out by hand without tools.
- Charges inside the phone — no separate charger needed; plug the handset into its usual charger and the phone manages the whole charge.
Build and Packaging
- Orange Amaya blister card — the sealed pack is marked "High Capacity Battery", showing the cell has not been opened or used before sale.
- Sealed, brand new stock — straight from the pack, unlike loose cells sold at kiosks with no history, labelling or traceable brand.
- Printed specification label — code, capacity, voltage and watt-hours appear on the cell itself, so you can verify exactly what you are buying.
- Flat removable cell format — a slim rectangular body that slides into the battery bay under the back cover and stays put.
- Amaya accessories brand — the Chinese maker behind the wall chargers, cables and power banks also stocked at Mascom International in Nairobi.
Safety and Care
- Replace a swollen cell at once — swelling signals internal damage, so stop using the phone and swap the battery straight away.
- Never puncture, crush or burn — a lithium-ion cell can overheat or catch fire if its casing is broken or heated.
- Keep out of direct sun while charging — heat on a dashboard or window ledge shortens the working life of any battery.
- Charge fully before first use — a new cell may take a few cycles before the battery indicator reads steadily.
- Recycle old cells — take a used battery to an e-waste collection point rather than the rubbish pit or a fire.
Inclusions and After-Sales
- One BL-25Bi battery — the cell itself, sealed on its blister card, with nothing else to assemble or set up.
- No charger in the pack — none is needed, because the phone's own charger tops up the cell inside the handset.
- 6-month Mascom warranty — covers manufacturing defects under normal use, with claims handled at our Nairobi CBD service desk.
- Free code check in store — bring the phone or old battery and staff confirm the match before you pay anything.
- Pay-on-arrival delivery — order on WhatsApp and pay when the battery reaches you, in Nairobi or any other county.
Package Contents
The Amaya BL-25Bi Replacement Battery ships as a single item: the BL-25Bi battery, sealed on Amaya's orange blister card. There is no charger or cable in the pack, and none is needed, because the cell charges inside your phone using the handset's usual charger. If your charger has also worn out, replacement chargers are available in store; bring the phone so we can match the plug. Check the seal when you collect, since an unbroken pack confirms the cell is brand new.
Warranty
Mascom International backs the Amaya BL-25Bi Replacement Battery with a 6-month warranty covering manufacturing defects under normal use. If the cell fails to hold charge or shows a fault from manufacture within that period, bring it to our Nairobi CBD service desk at the Old Mutual Building, where warranty claims are handled.
