I like AlzaPower products, but this one really didn't work. The display is basically useless there, because the vast majority of data on it are totally random numbers (checked by multimeter and thermometer) - charging currents, temperatures (both are significantly higher in real life than shown on the display - and when I write significantly, we are talking about a difference of 0.5 A or 20°C). This is related to the fact that the charger "blasts" the batteries with an absolutely absurdly high charging current (which leads to overheating, risk of battery failure and shortens its life), which cannot be regulated in any way. Batteries get so hot when charging that one is afraid to leave the charger "alone" in case a battery fails. And no, it's probably not a problem on the battery side - I have about five sets of AA batteries of different manufacturers, condition and age, all getting "loaded" exactly the same. This charger really failed.

The data on the display are totally random numbers, both temperature and charging current (measured with thermometer and multimeter). So the display is only there to "show something".
Unreasonably high charging current that cannot be regulated.

Easy operation
Applicable for all common battery types
Clear indication
SLOTS ARE NOT EQUALLY WIDE, which is not mentioned in any description! The outer ones are for cells with a diameter of up to 32 mm, but the inner ones are only about 20 mm. Larger batteries (like the 26xxx) can only fit three in the charger.
It has no current regulation - at most you can use a weaker power supply, which simply does not give more, but this is a bit awkward solution, moreover, functional only for a specific set of batteries

An overview of whether the battery is charged.
I don't know, after less than two weeks of use the charger started smoking. Fortunately, we were nearby, so we disconnected right away. But since it smelled like a burn, we're glad we didn't burn out. Alza has now sent us new goods, but I'm quite afraid to use them.

It can recognize the battery type, individual batteries can be monitored. After experience with no name chargers luxury.

It is supposed to have protections but the two things I described above show that it is not very good quality and I would worry quite a bit about the safety of using this device unsupervised.
Display with information
Different modes
Temperature sensor not working shows 29 but the flashlight is 47 degrees
A battery that has 1000 mah so it charges over 1000 mah

Three types of batteries tested with charging even fast I would say
I was buying a bigger version, with four slots but only two D batteries fit at a time! It is a question how much you can hold the smaller version of this charger, if only one or two.
