About -30 years... Jk, I have an old 8 track myself, and I usually get about four hours unplugged, but it's an old weltron player.

please test it by some defined flashlight, like maglite, imalent, fenix.
On average you should receive 20 playing hours from batteries in your tape player.
Guinness world record confirmed that Panasonic's EVOLTA AA batteries are the longest lasting.
a panasonic triple a battery last about 4 hours nonstop.
In my many years of using all different types and brands of batteries. I have found that Energizer is better than Panasonic Energizer last a lot longer than Panasonic also. The only reason I buy Panasonic ever would be if I'm low on cash because they are cheaper. I wouldn't recommend using them in anything you plan to use on an everyday basis.
It's the other way around - the batteries powers the flashlight. There's no set answer to that. It depends on the capacity/size of the battery, and how powerful the flashlight is.
No set answer to that, it depends on the capacity/size of the battery and the power consumption of whatever they're connected to.
If you want any batteries to last longer then put the batteries in your fridge and that helps them to last longer!!
Frozen batteries last longer unfrozen batteries.
It depends on the size and the use. Panasonic is a brand, not a size. Life of Panasonic BatteriesAs with any battery regardless of the brand, it all depends on how much power the device needs to operate it. For instance, in one of the new style LED flashlights, I've had a couple of "AA" cells last several months under heavy use. However, in my digital camera, they're gone almost as fast as I can put them in. The other factor is how long they've been sitting in storage, either at the store or at home. Since batteries work by chemical reaction they can over a period of time, weaken themselves. One of the tricks we techs use is to put the batteries in the freezer if we plan to store them for awhile and then completely defrost them before using them, usually by holding them in our hands until they're warm again. That way, it's possible to store batteries for as much as five years because it slows down the chemical reaction taking place inside the battery. And of course, the "other consideration" to keep in mind is that all batteries are not created equal. Some brands just last longer than others, and you'll have to experiment to find which battery works best and lasts the longest for you. I know I have my favorite brands and I've even been surprised by some that I didn't think would be worth the price.
Lithium batteries can last one and-a-half to two times as long as NiMH batteries.
