Model CM12A (0757-15CEC)

Schauer Charge Master 12V, 12A Fully Automatic Multi-Stage Smart Battery Charger, with Battery Clips and Ring Terminals. Microprocessor-controlled high frequency switching technology. For all vehicle & deep cycle 12 volt lead-acid batteries.

This Schauer Charger features an Advanced Multi-Stage Charging Process:
1. Initial Battery Qualification - Detects battery voltage, sulfation, internal impedance, and charge rate acceptance.
2. Enhanced Battery Rejuvenation - If the initial qualification detected that the battery was in poor condition, Schauer's unique rejuvenation process (patented in USA and Europe) will begin automatically.
3. Smart Charging Stages
• Soft Start Charging Mode (C.C. Mode) - Gently ramps up the battery voltage to 11V.
• Bulk Charging Mode (C.C. Mode) - Delivers an almost constant current of the maximum output until the battery voltage reaches the preset voltage value.
• Absorption Mode (C.V Mode) - The charging current tapers and the charging voltage is kept constant at the preset value without overcharging.
• Equalization charging - Process that carefully equalizes the battery by removing acid stratification and restoring the battery's full capacity.
• Analysis Mode (Battery Retention Test Mode) - Battery voltage drop analyzed to determine battery fault probability.
• Float Mode - Allows the charger to effectively be left connected to your batteries; maintaining the battery at a safe level of 13.6V, and ready for use.
• Maintenance Mode - The program engages a special charging waveform and monitors the battery voltage variance. If the battery voltage drops, the special pulses will keep the battery in an optimal state. If the battery voltage drops even lower, the battery charger will switch into Bulk charging mode. The Maintenance Mode allows the charger to safely be connected to the battery over the course of a season.

The CM12A allows the user to select from 3 Charge Modes:
• 1 Amp Maintenance Mode (Fan OFF).
• 8 Amp Silent Slow-Charge Mode (Fan OFF).
• 12 Amp Rapid-Charge Mode (Fan ON).

Features

• USER-SELECTABLE BATTERY TYPE - Select from "Calcium", "AGM/Wet", or "Gel" for a charging profile tailored specifically to your battery.
• FULLY AUTOMATIC - The charger can be left on the battery indefinitely.
• INTERNAL OVERHEAT PROTECTION: The battery charger has a built-in overheat and overload protection circuit. When the charger is overheated, it will decrease the charging current. If the temperature is decreased, the charger will resume normal charging.
• TIMER PROTECTION: The charger provides a time limit for each charging stage. If charging does not sufficiently progress through a stage before reaching the stage time limit, the charger will stop charging for the protection of the battery and the charger. This may occur if attempting to charge any severely discharged or heavily sulfated battery.
• REVERSE POLARITY: The charger has reverse battery protection. If a reverse connection to the battery exists (Red LED ON, while output leads are connected backwards), simply unplug the charger from AC power and properly remake the connections.
• SHORT CIRCUIT PROTECTION: The charger has output short-circuit protection. If a DC lead short-circuit condition exists (Red LED ON, while output leads are connected backwards), simply unplug the charger from AC power and properly remake the connections. The charger automatically detects the status of the DC lead connections. If the charger detects short-circuit or reverse polarity connections, it will not deliver any output current.
• ENERGY-SAVING ECO MODE: This charger has an ultra-low power consumption circuit and operates at very high power efficiency. The charger will automatically go into ECO mode if plugged in, but the DC leads are not attached to a battery. During ECO mode, the power consumption is less than 0.7W, equal to power consumption of 0.02kWh per day. After a battery is fully charged and during long term Maintenance Mode, the total power consumption is approximately 0.06kWh per day.

These are real nice looking industrial look, but bear in mind, they don't come with the shelves
First, understand that you only get the structure, not the actual shelves. The structure is decorative, industrial. piping, which looks really cool., especially in my utility room. I'm gonna get some hardwood for the shelving, so I don't have a picture yet, but I will as soon as I get that. The frame is very stable and strong. So thumbs up on the stability, structure and quality. The directions are straightforward, and all the parts are there. It looks real nice in my utility room and will look real cool when I've got the shelving on there. It's definitely a good value for your money if you need more storage shelving.

Perfect companion to other HBLYJS bracket systems — great aesthetic, versatility and functionality
I’m already a fan of the HBLYJS wall bracket system that I used in my daughter’s room, so I wanted to try this floor-to-ceiling option from the same brand for a slightly different look. The two coordinate perfectly — same black iron finish, same industrial-farmhouse aesthetic — and provided nice cohesion. What makes this system stand out is the flexibility in how you mount it. You can rest the uprights on the floor or hang them from the ceiling depending on your space and what works best structurally. That's a rare option and makes it easy to fit into rooms where a standard wall-mount wouldn't work as cleanly. I chose to hang them from the ceiling, because I personally love that look. Just make sure you mount these into studs! Like the bracket set, planks aren't included, but picking your own wood lets you match stain color and cut boards to the exact length you need. The heavy-duty pipe construction feels solid and the vertical design makes great use of wall space without eating into floor space. I definitely recommend the HBLYJS wall bracket systems for the great aesthetic, storage, versatility and functionality they provide. I will likely be buying a few more sets soon.

HBLYJS Industrial Pipe Shelving System
This shelving system gave my room a cool industrial look. The metal brackets feel heavy-duty and very stable. Installation took a little time but wasn’t difficult. I like that I can choose my own wood planks for customization. It holds a good amount of weight without sagging. The black iron finish looks great against the wall. This was a solid DIY upgrade for my space.

Easy storage, good holding power
This industrial pipe shelving system is a very nice way to add DIY storage to any room. The parts come well protected and are easy to assemble. They come with all the hardware one needs to install, though I used my own wall anchors because I like the ones I use and I know they work very well. I also decided in the end not to use the support legs because they would have had the shelves too low when mounted from the ceiling. Instead, I took those off and flipped the frames over so nothing would get in there, and I'll probably get nipples and caps from the hardware store to finish off the bottoms. The frames are finished in black, and resemble old galvanized gas pipes. As previously mentioned, assembly is easy enough and they accommodate whatever width of shelf you want to put up, within a reasonable limit. I used 36" shelves because that's the space I had to work with. The fact that each flange has three screws, assuming this is installed correctly, it should be rock-solid. I know mine is. I installed this in our laundry room / craft room in order to get more storage space, because it is so very busy in there. Given one could purchase the parts needed to build one of these for less, it's still a good value for the money because then after you buy those parts you have to clean and paint them, as well as prepare the boards. All I had to do was assemble these, and then prepare the boards, which made my life easier and the time saved was well worth the little extra. They also look fantastic with natural-colored oiled pine. I recommend these racks for their aesthetic, ascetic appearance, and their ability to hold a good amount of weight and storage, and not to mention if they're installed like mine, they will hold rolled leather hides like nobody's business.
