Dear Adafruit,

Thank you so much for your products.

I have a question to ask:

The batteries arrived fully charged and the power lasted for a long time. Now they both run out of power. I plugged them into a charging port and left each of them for two days in. However, the power lasts only for several minutes :(

Could you please advice me on what I am doing wrong?

My order No: 1613657-4903921068
Items: 2 x Lithium Ion Polymer Battery - 3.7v 500mAh[ID:1578] = $15.90
1 x Adafruit Micro Lipo - USB LiIon/LiPoly charger (v1) [ID:1304] = $5.95

Many thank you,

Uli

What voltage do you see between the pins of the JST connector?

make sure you're pluggint the microlipo in correctly - when no battery is attached you should still see the red and green LED's dimly lit

3.7/4.2V

There is never any light on microlipo - whether a battery is plugged or not

Hi again,

Thank you for your previous replies.

Could you please advice how long it usually takes to charge one battery. It’s plugged in for 2 hours already and the light is still bright red (haven’t changed on green to indicate that a battery unit is charged).

it charges at 100mA so if you battery is 500 mAh it will take 5 (500/100) hours or so
