Made of soft PVC, this pair of caps will safely cover and protect the positive end of your Ni-MH AA batteries. 

If uncapped, the exposed positive end may make contact with other metal, such as keys, coins or other batteries. They can short out or overheat which may destroy the battery's integrity and may become a fire hazard and vent Potassium Hydroxide. 

TIP: Some will get an extra pair and paint the end green or red to indicate fresh, charged batteries from used ones while on-the-go.
