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 kobalt abbau-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.
The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.
Also keep in mind that when your iPod mini battery does die, it requires a proper funeral inside a proper container. No you don't need to buy a casket and a plot but you do need to adhere to local lithium bettery stock laws when it comes to battery disposal.
On February 25, 1998, I went into a cold and deserted New York City area park and prayed for deliverance from alcohol, drugs and mental illness. I cried and fell on my face with outstretched arms begging for my freedom. In the invisible realm I sensed a heaviness being lifted, I felt bondages being broken, chains snapping and a sense of release. I walked out of that park a free woman.
For jobs where the batteries are required to be light weight as well as being reusable, then lithium batteries are ideal. But if a battery is needed to be very reliable or to remain unused for a long time then they might not be the right batteries for it.
