OptiMate 7 AmpMatic Silver Series Battery Chargers

The OptiMate 7 AmpMatic Silver Series is a fully automatic, multi-step smart battery charger and maintainer for 12 V lead-acid batteries, including AGM, GEL, EFB, and STD types. It automatically adjusts its 10-amp charge current based on the battery's size and condition, and features a "save" program to recover low-voltage, sulphated batteries as low as 0.5 V. This weatherproof charger is designed for long-term, unsupervised use to keep batteries in optimal condition. Key features: * Fully automatic: Connect the charger to the battery and it performs a fully automated 9-step charging process, requiring no supervision. * Ampmatic current: The charger automatically adjusts the charge rate to match the battery's size, delivering more current to larger batteries and less to smaller ones. * Battery saving: It can save and recover deep-discharged batteries that are sulphated, as low as 0.5 V. * Temperature compensation: It adjusts the charging voltage based on the ambient temperature to optimize the charge, ensuring it is higher in the cold and lower in the heat. * Long-term maintenance: It maintains the battery at a full charge and good health when left connected 24/7. * Weatherproof: The charger is built with a sealed case, making it weatherproof and suitable for both indoor and outdoor use in a wide temperature range. *Tested and safe: It includes a test phase to check the battery's condition before and after charging, and has electronic protection against short circuits and reverse polarity. *Versatile: It is designed to work with a wide range of 12 V batteries, from 3Ah to 400Ah, and is suitable for vehicles like cars, trucks, motorcycles, and boats.
