Review of Black and Decker Smart Battery Charger 30 Amp Fully Automatic Electronic Battery Charger - South African version: 12V charger at 220/230V:
Excellent value for money. I use this battery charger mainly to charge 105Ah deep cycle 12 batteries from a low output generator when camping at places where there is no power.
The red clamp gets a bit hot when in 30Amp mode but a wet cloth solved this problem.
This Charger can be set for gel or acid batteries. It can analyze the battery for voltage as well as the alternator of a motor car.
When you for example set it on the 30 Amp mode,
it first analyze the status of available charge and then automatically start at the highest safe amps that will not damage the battery and lower it in stages until it stops at the full setting. It can charge at 2 / 10 30 Amp settings and there is also a 80 Amp setting, not for charge but to boost for a quick start of a vehicle with a flat battery. It can charge a completely drained 12 battery of about 50 Ah in a little over 2 hours to completely full.
It can give you a digital output of the available voltage left in the battery.
The feature that originally persuaded me to buy this charger apart from the strong Amp output was that the manufacturer claims the charger to draw only 550 Watt.
I run this charger successfully from a small 650Watt 220V output generator which completely charge a 102Ah 12 deep cycle battery from 25% to 100% in just 5 hours on a relative hot day (about 30 degrees of C). The generator did not suffer and I am now secure of my power when camping.
The unit is not very big and light due to the exterior made of B$D's durable plastic.
If I must go out now to buy a charger again, I will make the same choice, and I am a very demanding buyer before I make my choice.
