The BL-49FT battery model name, typed as bl49ft or just 49ft, is a 5000 mAh, 3.85 V pack that listings match mainly to Tecno phones: the Spark 6 Go, Spark 5 Pro, Spark 5 Air and Camon 15. Some sellers add Infinix and itel models, but those claims are weaker.
Tecno, Infinix and itel share a parent company and reuse the BL-49 prefix, so the two letters at the end are what tell the packs apart.

BL-49FT, BL-49NT, BL-49PT: reading the suffix
All three start with BL-49 and all three are around 5000 mAh, which is exactly why shops mix them up. The suffix matters: BL-49NT fits a different set of Tecno and Infinix phones, and BL-49PT is listed for newer models such as the Pova 5 Pro. Two Tecno cells with identical mAh may still have a different flex cable or a few millimetres more length.
What the BL-49FT label looks like
A genuine BL-49FT sticker shows the code in large print, the 3.85 V nominal voltage, a limited charge voltage line, the capacity and a batch or date code. Tecno cells often carry a QR code as well. The suffix letters FT are printed right after the 49, with or without a hyphen. If the sticker on a new pack shows only "for Tecno" and a big mAh number, it is a generic part. Ask the shop to show you the sticker before the old cell is removed, so you can compare both labels line by line.
How to confirm before you order
On Spark and Camon handsets the model sits on the About phone screen inside Settings; Tecno model numbers start with letters such as KE or CD. Write that down, then compare the sticker on the old pack: BL-49FT, 3.85 V and a capacity near 5000 mAh. A new pack should carry the same suffix and a batch number.
Budget packs sold as BL-49FT online are often lighter than the original and claim 6000 mAh or more. Such a pack can swell within months. Weigh it against the old one and refuse it if it is clearly lighter.
Life and charging on a 5000 mAh Tecno
Spark phones use efficient chips, so a healthy BL-49FT usually lasts a full day and more with calls, chat and video. Charging is slow by modern standards, often 10 W or 18 W depending on the model, so a full charge takes two to three hours. If a replacement charges much faster than that with the same charger, its capacity is probably smaller than the label says.
Where to get it replaced
Tecno and Infinix service centres in India stock genuine packs for popular models. Take the phone, not just the code, so they can check the model number. See our mobile battery replacement guide and the list of Samsung, Motorola, Tecno and other packs.
