UPS battery Vs Car battery
Both UPS and Car batteries are available in lead-acid type as well as lithium-ion type. But despite the same technology used to produce these batteries, there are still many differences between them due to their application.
Most of the batteries available in the current market are still lead-acid based. Hence we will cover the difference between lead-acid based UPS batteries Vs Car batteries.
There are several types of Lead-acid batteries and some of the common types of batteries are mentioned below.
Classification based on configuration.
Flooded (also called Standard or Wet) battery
Sealed Type battery [also known as VRLA]
Classification based on application.
SLI Battery [Starting, Lighting and Ignition]
Deep Cycle Battery.
Both UPS and Car batteries are available in Flooded as well Sealed casing, hence to understand the difference between Car and UPS battery all you need to understand is the difference between SLI and Deep Cycle Battery.
SLI Battery (also called Cranking or Engine Battery) :
SLI stands for Staring, Lighting and Ignition. These types of batteries are developed to deliver a high burst of current for a short time [30 sec] while maintaining the battery terminal voltage of at least 12 Volt and then can be quickly recharged.
These batteries have relatively thin plates and a high plate count. This provides a large surface area of plates to react with the electrolyte to produce a higher amount of current quickly.
These batteries are also marked with CCA and CA ratings.
CCA rating of a battery:
In a cold environment, the ability of the battery to discharge current is low as compared to in a warm environment. CCA (cold cranking ampere) rating of a 12-volt battery, defines the ability of the battery to discharge current at -18°C (-0.4°F) for a time period of 30 sec while maintaining the battery term
