But it works - Chargers

So this is my second charger. The first charger I bought in 2010 is a Tenergy T9688 which I use at work and it works well. I needed one for my home and couldn't find the same one as before so I bought the TN299. The weird thing about these chargers is that if one charger tells you the battery is bad and doesn't try to charge it, the other charger will charge it. This happens in both cases, so I'm pretty sure I've thrown away good batteries in the past. So together they are 5 stars but…

Pros
  • High quality workmanship
Cons
  • Something else

Beta? Not ready for prime time!

A lot of people love this charger but my experience was just the opposite. Its ergonomics are terrible: you can't read the battery gauge graphic or switch positions. The battery charger sliders sound intimidating and are so poorly designed and manufactured that they are difficult to use in the first place. The worst thing is that the latest charger now rates almost new Tenergy NiMHd batteries as bad, while the chargers from other manufacturers only rate them as good. So I don't know if it's…

Pros
  • High test scores for grip and durability
Cons
  • Not as thick as other models

Much better than almost all other chargers

This is the best charger I have ever used, mainly because: A. It can work with almost every battery I have, including LiPO4, which is a lot good is. It features fully independent charging - with approximate status indicators - for each of the four battery bays. Most chargers work in pairs. I always seem to be charging an odd number or odd sets of batteries, so having everyone completely independent is really nice. So why not five stars? room for growth. eg: β€’ I wish it could charge more…

Pros
  • practical item
Cons
  • I will add later
