Battery heated gloves are ideal for motorcyclists, skiers, fishermen, and snowmobilers, etc. The gloves are made out of different types of materials and generally come with a soft and warm insulation that also pads the gloves. Some models are waterproof and/or windproof. Most of them are also adjustable and come with a small edison battery-ion battery in each glove that heats them up.
Power cords - Again, in my opinion, they are poor quality and might damage your electronics. Duct tape sand paper painter's tape lithium facts and bungee cords are good though.
All the phones now come with lithium ion batteries and charging should not be an issue ...although it's best not to charge them over 24 hours..Overnight every night is fine...they all do have a life though leaving it off when you don't need it can extend that. Although you would miss calls.
OThe first type of battery used in laptops was Nickel- Cadmium (NiCad). These can still be found in some older laptops. Their lifespan between recharges is about lithium bettery stock two hours however this decreases with each recharge. Also, if a NiCad laptop battery is charged for too long it may explode.
Now you want to discharge the battery. If you disable the hibernation setting or anything else that might make the computer go into power saving mode, it would be better. Let the computer run until it shuts down due to loss of battery power, then turn it back on.
So, in summary, if you have a PC which is showing clock errors or BIOS problems look first at the little 3 volt battery. It could save you a fortune. Happy computing!
