Tip 98: Don't throw away all the old batteries
When a toy or device goes dead and you change the batteries, it could be that all of the batteries are dead, or it could be that only one or two batteries are dead and the others are fine. Many people throw away all the batteries when they change the batteries. I use a battery tester and check batteries before I throw them away. Batteries cost as much as $1 each, so it is worth a few seconds to check.
Tonight I had a dead night vision goggle system that turned out to have 2 dead AA batteries and 3 good batteries. We also had an Airsoft BB gun that would not shoot- it had 2 dead AAA batteries and 2 good ones. So just tonight I saved 5 good batteries by checking the used batteries coming out of dead toys before throwing them away. Why throw away good batteries?
