Personal Battery Caddy

This is a line of battery cases available in many different presentations, colors and sizes for different battery types. We'll review the slim line because it is the most suitable for EDC.

There are 6 models in the slim line: 4xAA, 4x123, 6xAAA, 4x9v, 4xC, 4xD. Each model is available in different colors: GITD, orange, yellow, clear, red, green and black.

The caddy is constructed in solid plastic, each battery is well protected and locks in place with a small plastic tab, inserting and removing batteries from the holder is easy and the locking mechanism seems to be strong enough to be used thousands of times. Both the positive and negative contacts of the batteries are protected to prevent shorts.

The finishing of the product is of high quality, there are no sharp edges or pointy corners so you can put them in your pocket or inside a bag without any problems. The colors are bright, the glow in the dark version charges very well and glows bright for the first minutes with a glow enough to find them in complete dark for several hours.

There is no attachment point for a splitring, lanyard or a clip so you have to just drop the caddy inside a pocket or bag.

If you need to carry spare batteries the Personal Battery Caddy is a very high quality product with many versions available and will do exactly what you expect it to do: hold and protect your batteries.

ZST MBT Battery Tester

This is a battery tester that measures the battery capacity and not its voltage, the capacity is a far better way to know how much juice the battery has left, in many batteries the voltage will be constant until the cell is near exaustion so measuring voltage has no purpose.

This model can measure more than 30 battery types, including Alkaline, Lithium and Rechargeable C, D, AA and AAA batteries. Primary and rechargeables 123 and CR2 batteries.18500, 17650, 18650, 3v lithium coin like CR2016 and CR2032. A23 batteries, 9v batteries, and many others. It is practical to say that it will be hard for you to have a battery type that can't be measured with this tester. 104500 batteries can be tested even if not listed and some smaller batteries like 10440s can also be tested but it is not recommended to test more than once because the test may take a margin of the battery charge.

Using the tester is very simple: Put the battery with the positive pointing down in its place and use the small probe in the negative contact, percentage of remaining battery capacity is indicated on the LED bar display. The test takes aproximately 2 seconds per cell.

Given that mixing lithium batteries with different charge in a flashlight can result in an explosion (according to several reports) the tester is a good way to know both cells are in the same state of charge. A very nice tester that can be used in a huge number of batteries.
