Solid battery tester with the capacity needed to test four D-cells at once

Overall, I like the build quality and it seems to be a good tester unit (I own ten VP4+ units). One VP4+ (that I bought from Amazon) had an issue with the rubber zipper pulls on the case crumbling and breaking for some reason. I have been using a single pair of the USB test leads pretty extensively, and one of the spring-loaded probe ends has a habit of sticking in the retracted position. I'm not sure why, but it doesn't affect use of the tester significantly. A drop of mineral oil might fix it right up. I just wish the testers had an even larger capacity for my specific project needs. A 10-bay tester that could accommodate D-cells would be awesome!

  • What device/application do you use this with? Used to test and charge several hundred D-cell NiMH batteries

So far so good

The charger gives me confidence that the cells are being charged properly, and I can test them to sort out the ones that have might have some issues, before stringing them together to make a battery pack. I've only had this product for a few days, but so far it seems to be working fine. My only complaints would be: 1) That if you move it around, the power might cut out briefly. the DC power plug into the unit doesn't take any tugs to the side at all. If you are testing cells, this could set you back a few hours. 2) I wish it had a function to charge/discharge for storage. I have many cells that I probably wont use for a few months, it would be nice to test them and then return them to 50-60% charge for storage...

**** Charger

I purchased this on 2/26/2019. Within a couple months, the force of holding batteries in part of the charger - but not the other - twisted the cheap plastic chassis and it cracked. I taped it to prevent further twisting and it continued to function fine. That was, until today. Like some other reviewers, I now have an issue with the spring in the first slot. I had a battery sitting in there, untouched and charging, when I heard a loud snap. The spring inside has either broken or detached, and now the first slot of the charger is pointless. I won't be buying another one of these.

I wanted a really good charger.

I wanted a good charger that could charge a variety of types and sizes of batteries. After asking around and researching chargers. I purchased the XTAR Dragon. It was pretty new at the time and I paid double what they are selling for now. That being said I can rest assured that if I am not around and someone puts a battery in to charge it that it adjusts and charges it. I like a lot of the features this offers, plus I know that it has the ability to do stuff I haven't tried yet. I am happy with this charger, it seems to do it all.

  • What device/application do you use this with? All types of rechargeable batteries.
