Our wholesale rechargeable batteries are made with lithium-ion batteries. Lithium-ion batteries are long-lasting, low maintenance, and more environmentally friendly compared to other battery types. They have a long lifespan and can be recharged hundreds or even thousands of times before they need to be replaced and require little maintenance and do not need to be primed or conditioned before use. They are also more environmentally friendly than other types of batteries since they do not contain heavy metals such as cadmium or lead. Bear Rootz wants to keep the environment in mind. It is important to recycle lithium-ion batteries properly to minimize environmental impacts and recover valuable resources. Many countries have regulations in place to encourage the proper recycling of lithium-ion batteries. Two resources for finding a recycler are the Earth 911 database and Call2Recycle. You can also send individual batteries to specialized battery recyclers, retailers that are participating in take back services, contact your local solid waste, or household hazardous waste program for more options.
