Melting snow from yesterday - but there is the wonderful AL 800!

Battery automatic charger AL 300 per f. 2-6-12V batteries

Customer Review

The reality is different, can as the massive 5-star reviews suggest: this unit is definitely not recommended. Because it is an outdated underpowered part, which also still devouring a huge stand-by power.
But there is good news: a successor AL 800 is quite outstanding and therefore highly recommended! Since a good year, it is already available. It is based on modern high-performance and low-power switching electronics, the old AL 300PRO contrast to outdated inefficient transformer technology.

For comparison, the facts in detail:
(The values ​​apply to the new AL 800 / AL the old 300PRO)

max. Battery charging current: 850 mA / 180 mA
(Based on 36 Ah battery, car battery, with no-load voltage of 12.8 V own, so in good state of charge)
This results in a power output of the battery pack of 10.9 W / 2.3 W
this is the power (from the grid): 16.1 W / 9.0 W
As a result of this situation, an efficiency of 68% / 26%
Power dissipation (recording minus delivery performance) in this situation: 5.2 W / 6.7 W

For the purpose according to device usage, therefore, to maintain charged for a long time, the following applies. The periods in which there is a charging operation, in comparison to the time periods in which there is no charging operation, extremely low. You might very roughly be 2% of the total time, which is a device connected to the conservation of charge to a battery. This means that the standby consumption is a crucial factor for the energy balance of the equipment.

Power dissipation in standby operation (ie stand-by consumption): 1.8 W / 6.4 W
(Measured at the free terminals)

Including these values, the difference of the above efficiencies for both units is even more dramatic!

Electricity costs per year (see also Conclusion below): 4,40 / 15
Charging indicator light (yellow): yes / no
Weight incl. Terminals: 163 g / 343 g

CONCLUSION:
The new AL 800 has a four to five times net power at a third to fourth of the power loss over the old AL 300PRO.
For example, the case that an unused lead battery is kept fit over's year, the following applies: The new AL 800 used for only about 17 kilowatt hours (kWh) per year, the old AL 300PRO contrast, about 57 kWh (thus running a modern refrigerator three to four months). For about 26 cents for kWh electricity costs amount to at AL 800 only around 4.40 euros a year, the old AL 300PRO but around 15 euros per year. The AL 800 is only slightly in the price above the AL 300PRO and is to obtain cheap at the electronics shippers ELV, Pollin or Voelkner. Amortization of acquisition-costs in just a few months - super, right? And you will not only save dough, but especially valuable energy and doing what our environment and future.

Finally something different:
This review text I reingesetzt as little experiment here. Because I had noticed the blatant discrepancy between the vast number of positive reviews and the reality. After all, until now (early March 2013) evaluated in the just over two months since the first publication of five people my commentary to be helpful. And so far, it is registered as a single 1-star rating and is therefore in a prominent place. Everyone can therefore easily make knowledgeable about the facts. All the more surprising, I find, therefore, that are partly already in the daily rhythm unrestrained constantly rausgehauen new 5-star ratings, the authors / internal consistently noticed a particularly interesting rating scale: strong ignorance. Of course, you know Einstein's dictum that probably not only the universe is infinite ... And always were people who tried to open the people with facts eyes, fights or some even taken their lives (Socrates, Galileo, Sophie Scholl , ...). But it is not kind of cute, to get here in this tiny and super mundane individual cases may reflect an example, that there's nothing but purely nothing seems to have changed in today's hyper-media supplied and cluttered era? Can see what politics and society constantly show you here: that the ignorant cry of the large amount of rational and sustainable decisions and developments on issues such as energy policy, transport revolution, social justice, sustainability etc. pp. Prevented?
Well, now I'm curious how this little experiment goes on ...
