Multifunction Universal Digital Battery Charger

This is a convenient universal charger with 4 dedicated charging slots (each slot can charge the battery independently, no need to insert batteries in pairs). It works with almost every type of battery on the market including NiMH, NiCd and Li-Ion. Each slot has a spring retainer that is used to hold the batteries in place while charging. I love the versatility of this charger. It can be used not only for battery charging, but also as a tester/maintainer. The normal operating mode is charging…

Pros
  • Dual Mode - Two built-in modes: CHARGE and TEST. The charging mode has a current selection (300-1000mA) that allows you to set the charging current for each battery. While the test mode checks the capacity of your battery.
Cons
  • Something different

One of the best chargers to keep your NiMH batteries in good condition!

This charger is very good at eliminating mismatches when charging ALL THE SAME batteries! DO NOT use other brands of batteries and/or mAh batteries in this charger! It assumes they are all the same battery and constantly adjusts the power it puts into each battery based on battery resistance/ohms, voltage and possibly other measurements it takes. You can tell the batteries are getting warm when they are all aligned because they are being charged evenly. After a while, however, they stop syncing

Pros
  • Single charger. With four separate charging slots, the TN456 Smart Charger is not limited to charging in pairs or even the same cells. Each charging slot can be personalized for a specific battery to change its settings (charging mode/current). * Only charges 2 C size batteries at the same time.
Cons
  • Slightly torn

Get this if you want your rechargeable batteries to last longer.

Batteries are more volatile, as many of us know, requiring special charging techniques and careful separation to prevent overcharging and possible destruction. Tenergy TN456 answers the call. One of the reasons I like it so much is that it automatically selects the best charging mode over a wider range than comparable devices. In my cordless soldering iron, for example, I use the rare "Sub-C” nickel-cadmium rechargeable batteries. Only the TN456 can charge them correctly. It's also well made…

Pros
  • Intelligent design. With just one button, you can easily switch between display options to show charge/discharge capacity, battery voltage, charge/discharge current, internal resistance or elapsed time. The backlit LCD display is easy to see and read. In addition to charging batteries, the TN456 also features a USB port that simultaneously charges your portable devices.
Cons
  • Available in white only
