Frequently Asked Questions
Find answers to your most common questions about Waitley batteries, compatibility, shipping, and more.
Yes, Waitley batteries are fully compatible with original DeWalt and Makita chargers. The Waitley 20V range works with DCB102, DCB107, DCB115, and DCB118 chargers, while the Waitley 18V Makita batteries are compatible with DC18RA, DC18RC, DC18SD, and DC18SE chargers. You do not need to purchase any additional equipment to start charging immediately.
All Waitley high capacity tool batteries are CE, FCC, and RoHS certified. These certifications confirm that the products meet international safety and environmental standards. Each battery also includes built-in protection against over-charging, over-discharging, over-current, incorrect voltage, and short-circuit events.
The Waitley battery 5ah vs 6ah comparison comes down to runtime and weight. The 5Ah battery is slightly lighter and works well for shorter sessions or lighter tools, while the 6Ah battery offers approximately 20% more runtime per charge. For demanding or extended tasks, the 6Ah is the better choice, especially in the Waitley upgraded 20v real 6a plus version with its added USB charging ports.
The Waitley dewalt battery adapter acts as a converter that allows a 20V Waitley battery to power legacy 18V DeWalt tools. The adapter replicates the original DCA1820 interface and includes a USB port for charging small devices. It installs in seconds without any tools and provides a secure, stable connection for all compatible 18V cordless equipment
Protection mode is triggered by the battery management system when cell voltage drops below the safe discharge threshold — typically from leaving a battery fully discharged for an extended period. To reset, insert the pack into a compatible charger and leave it connected for three to five minutes. The BMS will detect the charger signal, verify cell condition, and exit protection mode to begin a normal charge cycle.
Waitley battery packs should be stored at approximately 40 to 60 percent charge in a dry location between 50°F and 77°F (10°C and 25°C). Storing a fully charged or fully depleted lithium-ion pack for extended periods accelerates capacity degradation. Recharging to the 40 to 60 percent range every three months during long-term storage maintains cell health and ensures the pack is ready for use when needed.
