How does the MXS 5.0 protect and extend battery life?

The charger uses a multi-stage charging process that adapts to battery condition and temperature, preventing overcharge and reducing sulfation with a dedicated reconditioning step. Built-in temperature sensing adjusts charge voltage so batteries receive the correct charge in cold or hot conditions.

• 8-step charging program that includes reconditioning and maintenance phases
• Temperature compensation to avoid under- or over-charging
• Spark-proof, reverse-polarity protected for safe handling
