Boat Battery Replacement
The Macgregor 26 came with just one battery. I have added a second one not only for safety reasons but also because we used the boat as an RV and needed backup power in remote areas on land and in water. The original battery was a general high cracking type and at that time, the second battery I added was similar. I used to manually switch between the two as needed. Eventually the original battery failed because I have used it to operate the various 12volts units such as fridge, 240V inverter, etc overnight and drain too much out of the it. I have replace the second battery with a Deep Cycle Type. A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. In contrast, starter batteries (e.g. most automotive batteries) are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity.
