What happens if you put non rechargeable batteries in a battery charger?
Furthermore, is it dangerous to charge non rechargeable batteries?
For one, a non-rechargeable battery, also called a primary cell, is known to overheat and some even explode when placed in a charger. Even if it does not explode, recharging non-rechargeable batteries still pose as a health risk. It contains toxic chemicals that could seep through when heated.
Additionally, can you recharge any battery?
Yes, alkaline batteries can be recharged. However, it is not considered to be cost effective and does have some risks. Recharging any battery can cause the production of gas within the battery. Nimh batteries had a higher capacity, more recharge cycles, and little or no memory effect compared to the NiCad batteries.
Storing batteries in a freezer can't actually charge them because there is no power source where the charge will come from. So storing them in a room with low temperature will extend the period retaining their charge. To make it clear, storing the batteries in the freezer doesn't help recharge batteries.
