Battery FAQs

What Dremel models are compatible with these batteries?

How do I properly charge these batteries for the first time?

Dremel batteries come partially charged. To ensure full battery capacity, we recommend fully charging your battery in the charger before using it with your Dremel tool. It is recommended that batteries be charged in environments where the ambient temperature is above 32 degrees Fahrenheit and below 95 degrees Fahrenheit. Additionally, it is recommended to store your Dremel tools and batteries in locations where temperatures will not exceed 120 degrees Fahrenheit.

Can these batteries be used in other tools or only Dremel tools?

What is the warranty period for these batteries?

How should I dispose of these batteries at the end of their life?

Lithium lon batteries must be collected, recycled, or disposed of in an environmentally sound manner. Dremel batteries carry the EPA certified RBRC battery recycling seal. This indicates that Robert Bosch Tool Corporation is voluntarily participating in an industry program to collect and recycle these batteries at the end of their useful life, when taken out of service in the United States or Canada. The RBRC program provides a convenient alternative to placing used Li-ion batteries into the trash or the municipal waste stream which may be illegal in your area. Please call 1-800-8-BATTERY for information on Lition battery recycling and disposal bans/ restrictions in your area, or return your batteries to a Bosch/Dremel Service center for recycling. Robert Bosch Tool Corporation's involvement in this program is part of our commitment to preserving our environment and conserving our natural resources.
