ZTS MINI-9RL Multi-Battery Tester

Indispensable pour une vrai évaluation.

This battery is well worth the price. It tests the battery under load, which is the only way to accurately test batteries. It test the most common batteries. Makes it easy to weed good from weak or bad batteries.I travel throughout Oklahoma shooting safety videos. My wireless mics use 9VDC batteries. The ZTS Mini-9RL lets me test the batteries before venturing hundreds of miles into the field for a shoot. If you want to really test your batteries, this is the meterm to buy.

Someone recommended that the poles be changed so that the negative side of the battery was used to make contact and the wire probe used to make a positive connection. I agree this would be a great improvement and make the device much easier to use. Labeling should also be updated to include some of the newer Ion type batteries.

You need a battery tester that actually puts a load on the battery to get an accurate testing. This is a great little tester. I have 2 of them. I will eventually have to take the plunge and buy the big one. You won't regret it you will reach for it all the time and it will pay for itself in batteries. So just do it already.

I love the fact that it uses a pulsed load to evaluate the battery condition, not just reading the voltage like cheaper testers. However, since I won't use this very often, and it requires four AAA batteries, I'll worry about them leaking out during storage. I sort of wish it had an external power source, but instead, I'll just remove the batt's when the unit isn't being used. Btw, it does a great job at evaluating Ni-MH batteries, which is one of the main reasons I chose it.
