30 minutes to full battery
The above is “ad-speak- deception”
Who knows what “charges” means in this ad speech, maybe “ 5 minutes of charging gives 5 minutes of runtime from a previously dead battery”
Lithium batteries can take in a lot of current when they are near zero voltage rating,
and the amount of this current is mostly limited by how well the battery is cooled.
The Skil ad emphasizes a new material is used inside the Skil battery to wrap each cell and carry away heat.
Remember: if anything goes wrong a fire from a $29 Li battery
can burn down your $150,000 garage or house
Edit:
From a review.
A fan to keep it cool, and the power jump feature that takes a dead battery to 25% in just 5 mins is an amazing feature in a pinch!
