Dell has a rigorous qualification procedure by which all Dell batteries are validated to make sure proper function, performance and safety. Some non-Dell batteries are offered in the market place with claims of compatibility with Dell systems. Dell can not verify these claims, nor the safety of making use of them inside a Dell program. Dell strongly encourages our customers to utilize only Dell laptop batteries advertised as appropriate for their laptop model. Only Dell laptop batteries come with a 1-year warranty, are engineered for optimal safety and performance for Dell systems, and are supported by Dell technical assistance for the length with the warranty period.
