Yes but nothing drastic. As the number of devices grows so do the number of rechargeable batteries in devices around you. TLDR You can charge non-rechargeable batteries but they might explode if you do so.

Recharge cordless tool batteries as soon as you notice a decrease in power. Never store NiMH in the refrigerator. Charging takes in between 1 and 25 hours with 4000 mW charge power. This can rupture the seal resulting in leakage of the contents or even explosion.
