It is better to use 20-amp charger.
Initially, the battery took an unexpectedly long time to charge using my NOCO GEN5X1 5-amp charger (over 60 hours). After contacting Eco-Worthy customer support, I decided to purchase their 20A 12V/24V Smart Battery Charger (SKU: US-L03CDQUS20A1-1).
UPDATE: After using the Smart Battery Charger, the battery charged from 23% to 100% in just over 8 hours. I recommend purchasing a smart battery charger in conjunction with the battery, especially if you don't already have a 20A charger. Eco-Worthy customer support was very professional and helpful, and I appreciate their assistance.
