Best tips for extend Dewalt DE9094 tool battery life
How to Extend the Runtime of Dewalt DE9094, DC9091 Power Tool Battery
Follow manufacturer guidelines to ensure the best cordless drill battery life. The rechargeable power tools battery lifespan depends upon how you use—or even fail to use— the drills, and how you store the tool battery when it's not being used. A few "best practices" help ensure those rechargeables last as long as the tools that require them.
Moderate Temperature, Longer Dewalt DE9094 Drill Battery Life - Allow the battery to reach room temperature indoors before recharging it. The temperature of the battery while it charges also affects its lifespan. If you are using a battery outdoors on a cold winter day, charging it outside could result in permanent damage that shortens battery life. The same holds true when charging a battery that's been exposed to summer heat and full sun all day. If you've used the battery in extreme conditions, allow it to sit for a few hours indoors, or in a location where it can reach room temperature, before charging it.
Storage On Battery Charger - Not all battery chargers are created equally, so reading the power tool's manual is the key to ensuring maximum battery life. For instance, leaving a typical tool battery on the charging base with the charger plugged in could overcharge the battery and shorten its life. Many companies recommend removing the battery from the charging base after the battery is charged. Dewalt recommend leaving the Dewalt DC9091 tool battery on the charging base with the base plugged in, thanks to a maintenance mode that keeps a battery fully charged, ready to use.
Self-Protecting Drill Batteries - Battery life shortens significantly when used in high-torque situations or when the cordless power tool's motor is under heavy continual load. The battery may overheat, which could shorten its usable lifespan. Many newer lithium-ion batteries, such as those made for Dewalt, Makita tools, feature intelligent circuitry that automatically shuts off power when under intense load. In this case, a series of lights flashes on the battery. The battery must cool again before reuse.
