For battery. The version .3 charges the 12-volt lithium-ion battery in just 30 minutes instead of three hours.
After that I could barely 20 holes perform (6mm drill about 4 cm deep).
Typical lithium ion I expect after a few charges over 30 holes to bewerkstellige so. For home use, I think that's quite sufficient. He probably is for normal drilling or screws without hammer, hold much longer.
Conclusion:. For home use super for drilling than the screws with the included adapter and bits I'll soon have to buy another Worx product to look like like this make up.
