When used correctly and with appropriate chargers, rechargeable batteries, particularly NiMH chemistry, are generally very safe for use in children’s toys. The primary safety concern arises from the potential for short-circuiting. If the positive and negative terminals of a battery come into contact with conductive materials (like metal objects or even other batteries if stored improperly), it can generate significant heat, potentially causing burns or even a fire. This is why proper storage in battery cases or original packaging is crucial.
Another consideration is ensuring the use of a charger specifically designed for the type of rechargeable battery being used. Using an incorrect charger can lead to overcharging, overheating, leakage, or even explosion of the battery, posing a serious safety hazard. It is imperative to always use the charger recommended by the battery manufacturer or a reputable, certified charger that correctly matches the battery chemistry and voltage. Educating older children about the importance of not dismantling batteries or putting them in their mouths is also a vital safety measure, as with any small electronic component.
