Difference Between Nickel Cadmium, Nickel Metal Hydride and Lithium Ion Laptop Batteries

Nickel Cadmium (Ni-Cd)

Nickel Cadmium (Ni-Cd) batteries were the standard technology for many years, but today they are old technology and new laptops don't use them anymore. They are heavy and very prone to the "memory effect". When recharging a NiCd battery that has not been fully discharged, it "remembers" the old charge and continues there the next time you use it. The memory effect is caused by crystallization of the battery's substances and can permanently reduce your battery's lifetime, even make it useless. To avoid it, you should completely discharge the battery and then fully recharge it again at least once every few weeks. As this battery contains cadmium, a toxic material, it should always be recycled or disposed of properly.

Nickel Metal Hydride (Ni-MH)

Nickel Metal Hydride (Ni-MH) batteries are the cadmium-free replacement for NiCad. They are less affected by the memory effect than NiCd and thus require less maintenance and conditioning. However, they have problems at very high or low room temperatures which might actually cause them to catch fire. And even though they use less hazardous materials (i.e., they do not contain heavy metals), they cannot be fully recycled (yet). Another main difference between NiCad and NiMH is that NiMH battery offers higher energy density than NiCads. In other words, the capacity of a NiMH is approximately twice the capacity of its NiCad counterpart. What this means for you is increased run-time from the battery with no additional bulk or weight.

Lithium Ion (Li-ion)

Lithium Ion (Li-ion) are the new standard for portable power. Li-ion batteries produce the same energy as NiMH but weighs approximately 20%-35% less. They do not suffer significantly from the memory effect unlike their NiMH and Ni-Cd counterparts. Also, their substances are less hazardous. Because lithium ignites very easily, they require special handling.

• Floating orb can be taken with you, so it acts as a portable speaker too

Navdy is the Heads Up Display (HUD) for Older Cars That Want to Upgrade

This is Navdy's first heads up display design. There might be minor cosmetic touch-ups before the final product is released.

Preorder Now - $299US (Full Price $499US)

Release Date - Early 2015

San Francisco-based company Navdy is offering a solution for people with older cars since. For $499, it's come up with a flat projector you can mount to the top of your dashboard with a heads-up display that shows you key information like navigation and caller ID. It combines that with an infrared camera and microphone that watches and listens for hand gestures and voice commands so you can control your phone without taking it out of your pocket. Think of it like eyes and ears for your phone, and one that you can use with multiple cars.

Navdy's big sell is to let you see certain apps and notifications in a single or split view, something you might not get on your smartphone. If you're driving with directions turned on and get a call, Navdy splits those things up on its screen. You don't miss out on where the next turn is supposed to be, and avoid having voice commands interjecting into your call from your navigation app. The same goes for texts and emails: if you get either, they'll pop up on the right while directions continue to run; and if you want them read out loud, you just speak a voice command or use a gesture.

Now you can be more aware of your surroundings while interacting with your smartphone contacts.

"We think this is the first time head up display technology has been combined with touch-less gesture recognition, and also a real head up display that works in cars offered on the market. There's kind of a lot of things that we've had to pull together, and the combination of those things really creates a magic experience that's far better than the individual pieces." 

-Doug Simpson, Navdy chief executive

Potential Features:

• Round watch face
• 44mm stainless steel case
• Inlaid button controls on the bezel
