I've been hearing mixed advice about battery charging. First, there were recommendations to drain ni-cad batteries completely before charging, and now I'm seeing tips suggesting that we shouldn't charge lithium-ion batteries past 80% to extend their lifespan. Should I be concerned about leaving my DEWALT batteries in the charger all the time?

Typically, I charge mine, check them monthly, and top off any that need it. I’ve found that keeping an eye on battery levels helps maintain performance!
I usually charge my batteries and then pull them off the charger as soon as they're done. If you only use your tools sporadically, they'll hold their charge just fine. No need to overthink it!
To get the most life out of your batteries, it’s better to avoid leaving them on the charger indefinitely. The general idea is that charging to 80% can lead to less wear over time compared to hitting a full 100% every time. If you’re using your batteries often, following a few best practices can help, but for casual users, it’s usually not a big deal. Just find a balance—don’t stress too much about it.
