Batteries used for cars, buses and trucks are Auto Batteries. These batteries are designed and build to provide a very large amount of current for a very short period of time to start the vehicle’s engine. Once the engine is running, the alternator in the vehicle takes care of all of the power needs of the vehicle and also quickly charges the battery back to its full potential.
Inverter batteries are designed to provide a small amount of current consistently for longer durations of time.All the backup power solutions, Inverters and UPS function by converting the DC current into AC current as all of our electric appliances run on AC power. UPS and Inverter batteries are also known as deep Cycle batteries as they discharged over a much longer time as compared to Auto batteries.
The design of these batteries is different.
The automotive batteries consist of large number of thin plates. This provides a large surface area of plates to react with the electrolyte to produce higher amount of current quickly.
The Inverter Batteries consist of lower number of plates which are much thinner as compared to auto batteries. The electrolyte volume of the inverter batteries is more so that the chemical reaction takes more time to produce current. This makes Inverter Batteries to provide a consistent amount of current for extended periods.
