Brownout - A steady state RMS voltage under nominal by relatively constant percentage.
1.5 Ah/10 = 150 mA (A cell's capacity is not the same at all discharge rates and usually increases with decreasing rate.)
Voltage Delay - Time delay for a battery to deliver the required operating voltage after it is placed under load.
Wall-less Design - A battery design where the structural support for the cells is formed by an open plastic framework.
Battery or Pack - Two or more electrochemical cells electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current levels. Under common usage, the term "battery" is often also applied to a single cell.
Thermistor - A temperature sensitive resistor, usually made from specially processed oxides.
UPS (single) - A UPS made up of one single UPS unit (rectifier/charger, inverter and bypass) and a battery.
