Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition. Dubbed the chargers with 'brains,' they are the first to fully-automatically reverse the primary cause of early battery failure known as 'sulfation'. Sentry SFR Ferroresonant series marine battery chargers are in an elite class, setting the standard for dependable battery chargers. They do all of this without ever overcharging, no matter how long they are left on charge - days-weeks-or even months. BatteryMINDers® are the new generation of SMART, pulse type 'computer-on-a-chip' chargers, that safely charge and maintain all size / type / brands of batteries including starter, deep cycle and sealed types including AGM 'dry' made by OPTIMA, ODYSSEY, EXIDE, INTERSTATE, et al. Our preference would be the USA made charger as they are more durable, last longer, and get the batteries to a fuller charger.
VDC Electronics provides 12-Volt or 24-Volt battery chargers/maintainers/desulphators for all your boating needs. With a larger battery such as yours we would recommend a marine 12v 10 amp charger such as the NOCO Genius 12v 10 Amp Marine On-Board Battery Charger, or a USA made Dual Pro 12v 10 Amp Sportsman Series On-Board Charger.
A BatteryMINDer® can extend the life of your Marine Battery.
