Warranty support also leans in favor of brand-name packs. While budget shoppers might lean toward replacements, long-term users often prefer the LBXR20 battery for peace of mind. For heavy tool use, the original still holds the edge. In the end, the choice comes down to balancing cost with trust. Many agree that the LBXR20 battery remains the safer long-term winner.
