TOPIC: Battery Storage
12 Volt Batteries, are the best bet for storing energy during the Aftertime, but where car batteries are the most readily available, Golf Cart batteries or Deep Cycle batteries work the best. A Variety of Types exist. Batteries Stored for later use need to be Fresh, and require Distilled Water and Sulfuric Acid. Batteries, even Ni-Cad, can become Dead but can get New Life and need to be Charged by a fast or Slow Charge, or Reactivated by a Desulfication pulser or perhaps a Reverse Charge, and need to be Maintained in any case. The State of Charge can be measured. Charging can potentially be done by Static Electricity, and boosting by Microwave. Overcharging should be avoided. Corrosion can be repaired. Two comprehensive PDF books are available to cover all aspects of battery maintenance - a book on Rebuilding Lead-Acid Batteries and another on Primitive Survival Batteries.
Battery use has its Limitations and can be Costly, but Consumption differs and Affordable systems are available. However, going Without Batteries is difficult, unless one uses a Diversionary Load technique. A Vital Power source, a Brownout solution, was constructed by a Troubled Times member as a Solution to meet his Concerns. Where electricity stored in 12 Volt DC batteries can be converted to AC to run higher voltage appliances, such as computers, there is Conversion Waste. A potentially good source of 12 Volt batteries in an emergency may be Cellular Sites used to power cell phones. Urine Batteries, Earth Batteries such as a Soda Can battery, or Fruit Juice Batteries can be constructed. The Boy Mechanic explains. Fuel Cells such as Hydrogen Cells, used by NASA in space, are a Potential battery type, with Plug Power focusing on residences. Lithium batteries have long life.
