Vekibee 2 Piece Solar Powered Sonic Mole Repellent Review

The unit is equipped with Polycrystalline silicon 2.5V/ 80 mA batteries. These batteries are known to have a better efficiency output and conversion rate, as compared to the conventional 2V/ 30 mA batteries. As such, the batteries need a 4-hour exposure to the sun for them to be fully charged. Once fully-charged, these batteries can last for up to 5 days.
