Li-ion Battery

vs

Lead-Acid Battery

Advantages of Panasonic Li-ion Battery Vs Lead Acid

High Rate Discharge

Compact Size

SOC/SOH Detection

Long Life time

High Rate Discharge when the power go down. Li-ion

battery have better High Rate Discharge compared to

Lead-Acid.

Li-ion battery can detect State-Of-Charge and State-Of-

Health. Therefore, you can use UPS anytime, therefore

no need to worry about battery levels and degradation .

Li-ion battery is about 2 to 3 times smaller in size

compared to Lead-Acid. So, Li-ion Battery is Space-

saving.

Li-ion battery is about Double or more Lifespan

compared to Lead-Acid.

You can reduce battery change and maintenance cost.
