Excellent Battery Charger - (EBC)
Pros: This is an excellent battery charger in my experience with numerous brands/models of "electronic" pulse/desulfating type chargers. I have tested other brands of pulse style chargers and the battery maintenance voltage was not correct for the various types of batteries, i.e. flooded cell, Gel, AGM - which all require a different maintenance voltage to be 100% charged without being over-charged. By using a lower voltage than the proper maintenance voltage required these other chargers never fully charged the battery. The BatteryMinder 128CEC1 performs properly at the correct maintenance voltages for all three battery types. In addition this charger comes with a temperature sensor to adjust the voltage based on ambient temp - which is important or the battery may not be fully charged or over-charged. BatteryMinder also offers special models of this charger for Odyssey, Gill and Concord batteries which require different maintenance voltages.
Cons: The quality seems excellent but these chargers are pricey IMO. No doubt this is a reflection of the charger's performance and consumer demand for quality products. IMO this is a perfect example of getting what you pay for so while pricey I have bought several of these 128CEC1 model BatteryMinder chargers because I need reliable charging/maintenance on expensive AGM and flooded cell batteries in classic/unique cars.
These chargers come with an excellent warranty though you probably won't need it. If you do however it's nice to know that you have a 5 year warranty. The ring terminal accessory is useful for vehicles that need to be quickly and conveniently connected to the charger.

After testing other brands of pulse/desulfating type battery chargers the BatteryMinder 128CEC1 proved to be the only model worthy of consideration due to the shortcomings of the other brands that I personally tested.

Great product
Pros: Now whether or not the charging algorithm does chemically desulfate the battery or not is still up in the air for me (this is some seriously advanced electro-chemistry and the effectiveness is debatable). I have done some brute force desulfating with good results using an adjustable DC power supply but it requires constant monitoring. However, I have checked this bad boy out with an O-scope and it does control itself very well and produces the pulses it says it does so at least there's a good implementation of that algorithm. Time will tell if it has restored the battery completely or just topped it up temporarily.
Cons: Nothing bad so far.
Lot's of good products and information on this site. Thanks!

Excellent product. Simple to use.
Didn't realize my "charged" batteries were only half charged by my standard automotive charger. Put the BatteryMINDer on all my car, truck, tractor and RV batteries and wow what a power difference. Not cheap put WELL WORTH the money.

Excellent charger, does what it says
Had this about 1 month now and it's worked perfectly. I had 3 batteries that my old charger would throw errors and no charge. The 128CEC1 noted the low condition of them and had no issues charging them to full. Layout is easy to read and the unit is very compact. Highly recommended. And Batterystuff was great to buy from as well, fast shipping.
