Remember batteries with memories? You had to go through all the nonsense of completely discharging then recharging your batteries or your battery developed a memory. After a while you only got half the use from your battery. Batteries are too expensive for that nonsense. Get AA lithium batteries and get full power from them first time and every time. Lithium batteries are especially important for high power items like cameras and flashes.
The La Crosse runs off batteries, but the batteries will last a very long time.
With energy charged into batteries during day time, or then with other means, motor. Solar power is not enough to power a car by it's own anyway.

Standard electric kettle normally takes about 1600-3000 watts to operate. No modern batteries can supply this kind of power for the needed period of time (about 3-5 minutes).
Yes, a spy pen does require batteries and most tenduse to use rechargeable batteries. You will find that as the battery power becomes exhausted, certain things may need reprogramming such as the time.
No, you can store power during the day in batteries, or heat sinks, and use that at night, but you can't gather solar power at night.
Energy Is an interdisciplinary engineering science having to do with the efficient
No they lose power over time depending of there usage. You can refres them but they can never gain they full power.
