SINGAPORE - More fires were caused by batteries of electrical bicycles, personal mobility devices and power banks last year (2016), the Singapore Civil Defence Force (SCDF) said in a press conference on Friday (Feb 17).

SCDF asked users of such devices to look out for faulty electrical circuitry and to avoid overcharging batteries, which could cause a fire.

Here is a look at four such incidents.

1. E-bike charging at coffee shop catches fire

Last September, an electric bicycle being charged at a coffee shop in Telok Blangah caught fire.

The e-bike was left at Block 12, Telok Blangah Crescent, when it caught fire.

Bystanders put out the fire before the Singapore Civil Defence Force (SCDF) arrived.

A taxi driver who saw what happened said the bike first made creaking noises before emitting smoke and bursting into flames.

2. Fire possibly caused by charging electric bike battery in Pasir Ris flat

On July 8, a fire broke out at Block 750, Pasir Ris Street 71.

It was possibly caused by an electric bicycle battery, which was left to charge.

A video of the fire showed flames in the flat, which was on the fourth storey.

No one was injured.

3. Two die in fire possibly caused by charging drone batteries

Two people died in a fire at Parry Avenue on June 9, 2015.

Investigations later found that the fire could have been caused by drone batteries, which were left to charge overnight.

The fire started in the wee hours of the night in the living room of the two-storey semi-detached house, where three drone lithium polymer batteries were charging on the carpeted floor.

The home owner's wife and his business partner died in the fire.

4. Electric bike sparks fire in Hougang flat

In January 2013, a fire broke out in an Hougang flat, sparked by an electric bike that was being charged.

Three people who suffered from smoke inhalation were rescued by SCDF, even though the blaze was contained in the living room of the third-floor unit.

An explosion was heard when the fire broke out in the flat at Block 619.
