When asked which power tool brand someone should go with, most pros and experienced DIYers will drive home the importance of battery power, battery life, and availability before they mention special features, speeds, or durability. That’s because, without reliable batteries, the tool extras. .
One of the most common ways DIYers kill their batteries’ potential lifespan is by keeping them on the charger. This can cause overcharging, which will result in a drastically shorter usable lifespan. A better course of action is to remove batteries from the charger. .
On the opposite end of the spectrum from overcharging, putting dead batteries away for long periods will also kill their capacity to hold a charge over time. You can avoid this by swapping to a. .
At this point, it might seem like batteries are the Goldilocks of the tool world, but you should not store batteries fully charged. First, fully charging a battery will shorten its lifespan.. .
If they’re not paying attention, it’s very easy for a DIYer to run a battery down until it’s completely dead, but deep drains aren’t good for modern battery chemistry. Also, with older nickel-cadmium batteries, it was recommended to drain them completely before storage.. [pdf]
