The purpose of the battery:

Current technology allows batteries to operate at high temperatures with a temperature range of -20 degrees. Up to + 50. They left an impression, but that doesn't mean that life in this area is the same. I am sorry! Maximum safe temperature, maximum battery life is 20. It is good to place the battery in a cool place on the boat, preferably in a storage compartment below the seat, where the temperature of the tank cools and prevents overheating. Do not use ACID batteries on the pontoon. The space is small. In addition, the acidity of the bottom of the acid battery will cause burns and clothing damage
