Two-pack Li-ion batteries

The set supplies two 3.7 V 890 mAh BL-5B cells and a compact AC charger that accepts 100–240 V input and delivers 4.2 V at 600 mA. A fold-flat plug makes the unit easy to pack, while the built-in LCD shows red during charging and green when the cells are full or on standby.

Folding plug and LCD status remove guesswork

The flat-pin design lets the charger sit flush against a wall socket or power strip without blocking adjacent outlets. The screen replaces simple LEDs, so you can confirm charge progress at a glance without unplugging the unit.

890 mAh capacity per cell decides suitability

Each battery stores 4.26 Wh, matching the original BL-5B rating for the listed Nokia, Rollei and other compatible handsets. Devices needing higher capacity or a different form factor will not work with this pack.

Questions about this item

How often will the 890 mAh Li-Ion batteries need replacing?

Li-Ion cells typically last 300–500 full charge cycles before capacity drops noticeably; with two batteries you can rotate them to extend the interval between replacements.

What stops the charger from running indefinitely when left plugged in?

The smart LCD charger switches from red (charging) to green (standby/full) at 4.2 V 600 mA output, so it stops delivering current once each 3.7 V cell reaches full charge.

Does the foldable-plug charger get hot during all-day charging?

Input is 100–240 V AC at 50–60 Hz with only 600 mA DC output, so heat stays low; the green LED confirms standby once the 4.26 Wh batteries are full.
