DeepSea Power & Light SeaBattery & Charger

Available to rent

The High-Current SeaBattery takes the already versatile SeaBattery to the next level by allowing users to draw up to 100 amps. 


The High-Current SeaBattery takes the already versatile SeaBattery to the next level by allowing users to draw up to 100 amps. The power module is a pressure-compensated submersible battery pack designed to perform at any depth, even the high pressure, low temperature environment of deep ocean trenches. Routine deployments to 6,000 meters as part of sea floor instruments and towed camera sleds have proven the SeaBattery power module to be both reliable and robust in the most demanding of subsea applications.


Power & Light Charger

MajorCharge Pro Battery Chargers can be used to recharge virtually any type of battery, including conventional liquid electrolyte, maintenance-free absorbed electrolyte, deep-cycle, and gelled type batteries. The MajorCharge Pro features patented three-stage constant current, constant voltage charging format.

A constant current bulk charge MajorCharge Pro applies to achieve the fastest possible return of energy to the battery. This constant voltage stage is proportionally timed and temperature compensated, minimizing electrolyte breakdown and gas emission.

The final standby float charge stage will replace standing losses and keep the battery in a fully charged state & "Ready" mode. As soon as the battery is connected, a desulfation circuit encourages the breakdown of large sulfate crystals which can develop during prolonged periods of deep discharge.
