Four fire engines and around 25 firefighters tackled a fire at a waste site on Gibbs Road in Edmonton.
Around four tonnes of general waste was destroyed by the fire. There are no reports of any injuries.
The fire is believed to have been accidental and was caused by the failure of a lithium-ion battery in a power bank.
A London Fire Brigade spokesperson said: "Lithium-ion batteries and electricals with hidden lithium-ion batteries should not be placed in the same bins as your regular rubbish or recycling. Instead, check with the retailer or your local authority's website for the safest way to dispose of lithium-ion batteries in your area and reduce the risk of fires occurring.
"Lithium-ion battery fires are a major risk. We’ve seen a growing number of fires at waste disposal sites that are believed to have been caused by a lithium battery.
"Although lithium-ion battery products that have been built to a poor standard are a higher fire risk, any battery is at risk of exploding and catching fire if it has been crushed or becomes damaged. Lithium-ion battery fires can be ferocious and can spread in seconds.
"Fires that we attend at sites like recycling centres and scrap yards can be very time consuming for our firefighters and often require a high level of resources to put the fire out. We’ve also seen the detrimental environmental and societal impact these fires can have on local communities."
Control Officers took the first of two calls at 1651 and mobilised crews to the scene from Edmonton and Tottenham fire stations. The fire was extinguished by 1847.
