Kobalt 40V Battery Charge Time

If you’re like most people, you probably don’t think too much about the battery in your power tools. But if you’re a Kobalt 40V user, it’s important to know how long it takes to charge the battery so you can plan your projects accordingly. Here’s what you need to know about Kobalt 40V battery charge times.

So if you’re working in freezing temperatures, make sure to give yourself some extra time for the battery to charger completely. Bottom line: If you’re using a Kobalt 40V tool, plan on spending about 4 hours charging the batteries when they’re fully depleted. Keep an eye on the weather and temperature conditions to be safe, and always have extras on hand so you can keep working on your project without interruption!
