Frequently Asked Questions - VLEVP2 VELLEMAN
What types of batteries can I charge with the VLEVP2?
The VLEVP2 is compatible with rechargeable Li-ion batteries with nominal voltages of 3.0 V / 3.2 V, 3.6 V / 3.7 V, or 3.8 V, including sizes 10440, 14500, 14650, 16340, 17670, 18350, 18500, 18650, 18700, 22650, 25500, and 26650. Do not use non-rechargeable batteries or other chemistries.
How to choose the appropriate charging current?
Use the CC button to select 0.25 A (for small batteries like 10440 to 18700), 0.5 A (for batteries from 18700 to 26650 with capacity ≥ 2500 mAh), or 1 A (for batteries with capacity ≥ 2000 mAh for fast charging). Refer to the manual for optimal choice.
What do the LED indicators mean?
During initial self-check, the indicator is red for 2 seconds. In standby, it is green. During charging, it is red. When the battery is fully charged, it turns green again. In power bank mode, the color indicates the charge level of the inserted battery.
Can I use the VLEVP2 as a power bank?
Yes, if you insert a Li-ion battery of at least 2000 mAh in channel CH1 and the charger is not plugged into mains. Press and hold the charging current button for 1.5 seconds to activate the USB output. The LED indicates the remaining charge level.
How to set the charging voltage?
Use the voltage switch on the charger to select 3.2 V, 3.6 V, or 3.8 V. For example, for a nominal 3.6 V/3.7 V battery, choose 3.6 V. Make sure the voltage matches your battery.
Can the charger revive deeply discharged batteries?
Yes, the VLEVP2 has a 0 V battery activation function. It starts charging gradually. However, if the battery is too damaged, it may not be recoverable.
What if the screen shows no level bars?
This may indicate that no battery is inserted, there is a short circuit, the battery voltage is below 1.0 V, or the battery is reversed or poorly connected. Check polarity and battery condition.
Can I charge two batteries of different voltages at the same time?
Yes, the two channels are independent. You can charge batteries of different voltages if you set each channel to the appropriate voltage. Select the voltage via the switch for each channel if necessary.
Does the charger stop automatically?
Yes, once the battery is fully charged, the charger stops charging and the indicator turns green. If the battery remains in place and its voltage drops below a threshold (3.9 V or 3.3 V depending on configuration), an automatic recharge cycle starts.
How to clean and maintain the VLEVP2?
Unplug the charger and clean the case with a damp cloth. Do not use abrasive products. Keep it away from water, excessive dust, and extreme temperatures. No special maintenance is required.
