Product Description

Size: AA | Unit Count: 8

Product Description

The Fluke Networks MS2-100 Microscanner2 cable verifier verifies voice/data/video (VDV) cables and multimedia sources on common media types, including RJ11, RJ45, and coax. The meter displays a graphical wiremap, cable length, cable ID, and distance-to-fault. A tone generator produces digital and analog signals to locate cable or wire pairs. Digital mode locates high-grade cabling, including Category 5e, Category 6, and Category 6a in bundles or at switches, patch panels, and wall outlets. Analog mode verifies Category 3 and below voice-grade cabling, coax, security, alarm, and speaker wiring. VDV service detection verifies media services, including powered 10/100/1000 Ethernet switches, plain old telephone services (POTS) voltage and polarity, and Power-over-Ethernet (PoE) voltage and pairs. A backlit LCD is oversized for clear viewing in a variety of lighting levels, and a rubber holster protects the meter in rugged environments. Copper and fiber testers are used by network technicians to troubleshoot, maintain, and optimize performance of copper and fiber optic cabling, hardware connections, and network settings in enterprise networks.

A copper cable tester is a device for troubleshooting, inspecting, and certifying copper network cabling. Devices range from one-button tools for checking connectivity to complex tools for certifying network installations. Three types of testing include verification, to test whether a connection or cable is functioning correctly; qualification, to test a network's ability to support specific speeds and functionality; and certification, to verify whether a network installation meets industry standards. Cabling contractors, installers, and network technicians use copper cable testers to set up and maintain networks within a building or on a campus in corporate, academic, manufacturing, and other enterprise network environments.

Fluke Networks, a division of Fluke Corporation, manufactures tools and software for network deployment, performance management, and troubleshooting. The company, founded in 1992, is headquartered in Everett, WA.

Unit Count: 4Size Name: AA
The Energizer L91 Lithium AA cell is a fantastic power source. For high-drain applications, it offers great advantages over ordinary alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is important to recognize the strength of L91, and use it only in applications that give you the best results. Otherwise you'll be wasting your money.

According to data sheet published by Energizer, the capacity of the Lithium AA cell (L91) is 3000mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the Energizer E91 AA) is rated as 2800mAh, but only at a very light load of 25mA. At a heavy load of 1000mA (typical for a digital camera or flash unit), its capacity drops to below 1000mAh. This number gets even worse at low temperature. At zero degree C and 1000mA load, the L91 can provide about seven times more energy compared to the E91. This is where the marketing claim of "Last up to 7 times longer" comes from.

When used in a digital camera at room temperature of 25 degree C, the L91 is more likely to last 3-4 times longer than alkaline. This is enough to justify its price, which is also around 3-4 times higher than alkaline. However, in low-drain applications (such as smoke detector, wireless mouse or remote control) alkaline cells will last just as long at a fraction of the cost.

The L91 also contains much higher energy when compared to an ordinary rechargeable NiMH cell such as the Energizer NH15-2500.

[Updated on June 8, 2011]
Note: Amazon has moved two of my previous reviews (one for Energizer Lithium AA 4-pack, one for 8-pack) under one page. Therefore I have to update my review to add some new information - or else I look like a fool who says the same thing twice.

=== New information follows ===

There seems to be some confusion about those Energizer Lithium AA batteries. Several people have bought those batteries under the assumption that they are rechargeable, only to be disappointed later.

Despite the name 'Lithium', those Energizer Lithium AA batteries are very different from the commonly known 'Lithium-ion' rechargeable batteries. Namely:

- They are single-use batteries (NOT rechargeable like Li-ion)
- The terminal voltage for each cell is around 1.65V (compared to around 3.7V for each Li-ion rechargeable cell)

The two types of batteries are not compatible. If your camera accepts AA cells, then you should use those Lithium AA cells and not Li-ion rechargeable battery. Alternatively, you may explore other rechargeable battery options, namely:

1. Low-self-discharge NiMH AA cells, such as Sanyo Eneloop or Sony Cycle Pre-Charged. Those have a operating voltage of 1.25V per cell, so some cameras (especially those that use only two cells) may not operate correctly on those.

2. Nickel-Zinc rechargeable such as PowerGenix AA.

The Energizer L92 Lithium AAA cell is a fantastic power source. For high-drain applications, it offers great advantages over ordinary alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is important to recognize the strength of L92, and use it only in applications that give you the best results. Otherwise you'll be wasting your money.

According to data sheet published by Energizer, the capacity of this Lithium AAA cell (L92) is 1200mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the Energizer E92) is also rated as 1200mAh, but only at a very light load of 25mA. At a heavy load of 500mA (typical for a P&S digital camera), its capacity is reduced to about one-third. The difference gets even greater at low temperature. At zero degree C and 500mA load, the L92 can provide about seven times more energy compared to the E92. This is where the marketing claim of "Last up to 7 times longer" comes from.

When used in a digital camera at room temperature of 25 degree C, the L92 is more likely to last 3-4 times longer than alkaline. This is enough to justify its price, which is also around 3-4 times higher than alkaline. However, in low-drain applications (such as smoke detector, wireless mouse or remote control) alkaline cells will last just as long at a fraction of the cost.
