About Covid - you need to avoid DIRECT contact with infected people.

Yes, this battery is really good. It has Cold Cranking Amps (CCA): 450, Reserve Capacity (RC): 66, Ampere-Hour (AH): 38, and it is a Dual Purpose AGM Battery. This means that it has enough power to start (even in cold weather) and more time to last.
Another good option is Exide Edge FP-AGM51R...
