How to connect a battery in Series?
The positive terminal of the first battery is connected to the negative terminal of the second battery, the positive terminal of the second is connected to the negative of the third, etc. The voltage of the assembled battery is the sum of the battery voltages of the individual batteries. So the batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged.
What is a marine battery?
Marine batteries are considered a "hybrid" battery which actually falls between the starting and deep-cycle batteries. Marine batteries are usually rated using "MCA" or Marine cranking amp which is rated 32 degrees F, while CCA is at zero degree F. (For more information on CCA, CA & MCA, please see below)
What is the CCA rating?
The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V.
Are lead acid batteries recyclable?
Lead is the most recycled metal in the world today. The plastic containers and covers of old batteries are neutralized, reground and used in the manufacture of new battery cases. The electrolyte can be processed for recycled waste water uses. In some cases, the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte. In other instances, the sulphate content is removed as Ammonia Sulphate and used in fertilizers. The separators are often used as a fuel source for the recycling process.
