The blaze broke out in Edinburgh Way, Harlow, at around 11am on Friday, August 15, near the River Way roundabout, and led to widespread disruption.
Roads were closed for several hours as emergency services responded, and work continued into the early hours to make the area safe.
Harlow Council believes batteries placed in household waste may have been the cause of the fire.
Councillor Nicky Purse, who is responsible for environment, said: “This incident could have been far worse, and it highlights the very real risks of putting batteries in your general waste.
“Batteries can ignite or explode when damaged or crushed, especially in bin lorries.
“We urge all residents to use the free battery collection service provided by the council.
“It’s simple, safe, and helps prevent dangerous incidents like this.
“Let’s all do our part to keep Harlow safe.”
The council’s free battery collection service is available to houses but not flats or communal properties.
Batteries should be placed in a clearly labelled cardboard box or plastic bag and left next to the black wheelie bin or purple bags on non-recycling collection days.
