Variable Length Flexible Battery Tester (1.5V/9V)

Pros: Works well without having to power it with separate battery power. Easy to read scale quickly informs tester of remaining power remaining in the battery. Tests many sizes & is pretty acurate.

Cons: A bit lean on the build side, though for the money & occasional use one simply cannot go wrong with this portable unit.

Other: For the price you truly cannot go wrong. Will make wonderful gifts to anyone who uses a lot of batteries. Cool little unit!

Pros: Cheap battery tester that does 9 volt batteries as well

Cons: just a cheap plastic gadgget with resistors inside

Other: its ok, if you don't have a battery tester buy this for cheap

Pros: Affordable & portable, lightweight flexible (will test many different battery types), this handy tester reads voltages at an acceptably accurate manner. Easy to read & handle as well.

Cons: A little on the cheap end build-wise, but hey!: considering the price there is no real complaint here in this.

Other: Not only is this deal worth it but they would make great little gifts as well. Can' go wrong in purchasing these small wonders!~

Pros: Valuable for anyone who wants to know the charge of batteries.

Cons: Dial almost always sticks at max when first measuring a battery, regardless of charge (shaking it is the only way to reliably unstick it).
A fully charged battery and one that's borderline have only a few mm difference on the dial between them. Only truly dead batteries venture into the red zone.
Poor slide mechanism.

Other: Overpriced considering the dodgy build quality, but I don't exactly see any other battery testers around. A must for anyone who has no other method of testing batteries.

Pros: easy to use, tests all common batteries

Cons: could be smaller, doesn't have spring on sliding test part.

Other: if you need one, get one... but with multimeter you can do lot more...

Pros: good test

Cons: wire on mine broke inside

Other: great for price but might break

Pros: It works and helps you to understand how much energy your batteries have approximately. It can measure lots of battery types.

Cons: Cheap material. Looks like it has a short usefull life and will break down rapidly.

Other: It has a cheap material.
it's fragile
Looks like doesnt have a long life
Dont give the exact mAh value.

But it works and helps you to measure your batteries overally and it's cheap. If you need a gadget such like that, buy one.

Pros: - Works on almost all batteries! (Including button batteries)
- The price is OK for this product.
- 2 different volt readings, one for button batts and one for the rest.

Cons: - Build quality, looks a little cheap and probably is, but i haven't had any trouble with it. Should last long if handled with care.

Other: You get what you pay for! If you need a tester to show aproximatly how much there is left on your batteries, this is the one.

Pros: You can understand whether your batter is full or not and you can seperate the usefull ones from a batch of bateries.

Cons: You cant understandt exactly how much battery power does it have. Its needle is not usefull to show the level. The colors of the graph are not helpfull.

Other: You cant see very well how much power exactly does it have but you can buy it if you need. Built quality is very low. It's not for a professional use.

Pros: This is the gadget you ever wanted without knowing you needed. Can test the most popular models of batteries. I can't believe that took so long for someone build and sell such a thing, since the batteries exist and are very popular for many many years. The price is very good.

Cons: Useless to test CR123A, CR2 or others with voltage different than 1.5v.

Other: I bougth another, because my father kinda "stole" mine. He loved that too.
