Most of the battery chargers I've tested , and this includes ALL from Harbor Freight and Sears will not put out 14.3V to bring a battery all the way back to full charge. The B&D as listed above is the only one.
I bought brand new Johnson Control batteries (Walmart) and simply couldn't get them to full charge. Tried my big SEARS charger/starter, tried my old SPORTMAN 10A, tried the $27 Harbor Freight, tried the 12V outlet on my Honda 2000 generator. Nothing would bring the batteries full. The B&D was ordered from Amazon and arrived last weekend. In 48 hours it had the batteries singing and my Trimetric 2025RV FINALLY reading correctly and showing proper full charge.
If you don't bring the battery back to a full charge with 14.3V you are killing your batteries slowly but surely.
The converter in my truck camper will only put out 12.7V....Terrible! All of the other chargers in my arsenal will only max out to 13.2V....Not good enough!
If you have a GEL or AGM battery this is even more critical as these batteries require a much higher charge rate than Wet batteries.
There are many, many articles on the internet about this...All riveting reading!.... :-)
