2. Nickel–zinc battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–zinc_battery

   Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.

   3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries (Matchstick for reference). This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.

4. Nickel–hydrogen battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–hydrogen_battery

   A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]

5. Nickel–cadmium battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–cadmium_battery

   At one point, Ni–Cd batteries accounted for 8% of all portable secondary (rechargeable) battery sales in the EU, and in the UK for 9.2% (disposal) and in Switzerland for 1.3% of all portable battery sales. [7] [8] [9] In the EU the 2006 Battery Directive restricted sales of Ni–Cd batteries to consumers for portable devices.

6. Nine-volt battery - Wikipedia

   en.wikipedia.org/wiki/Nine-volt_battery

   The nine-volt PP3-size battery is commonly available in primary zinc–carbon and alkaline chemistry, in primary lithium iron disulfide and lithium manganese dioxide (sometimes designated CRV9 [2]), and in rechargeable form in nickel–cadmium (Ni–Cd), nickel–metal hydride (Ni–MH) and lithium-ion.

7. Nexus 6P - Wikipedia

   en.wikipedia.org/wiki/Nexus_6P

   The phone arrives running Android 6.0 Marshmallow. Compared to its predecessor Android 5.x Lollipop, the most significant changes include a new permissions architecture that allows for fine-grained control of app permissions instead of bulk permission granting during app install, and Google Now on Tap, an ability to perform a Google search based on the information currently displayed by ...
