HP is recalling some laptop batteries due to concerns that overheating could cause fires and inflict burns.

The company issued the worldwide recall on Thursday, urging customers to check batteries in several laptop and mobile workstation models sold between December 2015 and December 2017.

The affected batteries shipped with certain HP ProBook 64x (G2 and G3), HP ProBook 65x (G2 and G3), HP x360 310 G2, HP Envy m6, HP Pavilion x360, HP 11 notebooks, and HP ZBook (17 G3, 17 G4, and Studio G3) mobile workstations. Some of the affected batteries were also sold as replacements.

In many cases customers won’t be able to replace the batteries themselves since the power cells are internal, so HP is covering the cost of installing a replacement via an authorized technician.

The recall affects around 0.1 percent of HP systems sold globally over the past two years, HP told ZDNet sister site CNET.

The US Consumer Protection Safety Commission (CPSC) says about 50,000 units are affected.

Machines affected by HP’s battery recall include certain HP ProBook models, as well as other laptops sold between December 2015 and December 2017.
