DeWalt DCB205 20V MAX Battery

When using a standard DeWalt DCB115 4-amp charger, it takes roughly 90 minutes to fully charge a completely dead DCB205 battery. If you upgrade to the rapid DCB118 fast charger, that charge time drops to about 45 minutes. The battery also features an LED fuel gauge to let you know when it is ready to go.

Yes, the DCB205 utilizes the standard DeWalt 20V slide mechanism, meaning it is 100% compatible with all 20V MAX tools, including the newer Powerstack models. DeWalt designed their 20V line to be universally compatible, so you can use this older battery on new impact drivers. It will also work on their 60V tools like the Flexvolt circular saw when used in a multi-battery configuration.

No, like all lithium-ion batteries, the DCB205 will drain rapidly if left in freezing temperatures below 32 degrees Fahrenheit. Cold weather increases internal resistance, causing the battery to deliver less power to your drill or saw. For optimal lifespan and power delivery, DeWalt recommends keeping the battery at room temperature before use.

Yes, the DCB205 has more than double the cells of the standard 2.0Ah battery, providing roughly 2.5 times the runtime on a single tool. This makes it an excellent upgrade if you are using high-drain tools like the DeWalt weed eater or circular saw. It is noticeably heavier than the 2.0Ah pack, but the extended runtime is worth the weight trade-off.
