Product Description

Features & Benefits:  
BatteryMINDer® Model 128CEC2: 12-Volt 2/4/8 AMP Lead Acid Charger-Maintainer-Desulfator & Lithium Charger Maintainer

User-Selectable Settings for All Sealed / Wet (filler cap) /Maintenance-Free / AGM / Deep Cycle / RV / Marine / PLT and Odyssey brand Lead-Acid** based Batteries. Diagnoses battery’s condition – can predict failing batteries before they die. For ALL 12-Volt Sealed and Wet “Filler Caps” Batteries Including AGM, PLT and Odyssey®. This BatteryMINDer® is an Odyssey-approved charger.  


Selecting the Correct Amperage for Lead Acid Batteries:

All BatteryMINDers are regulated and will not overcharge, no matter what amp selection you make. It is just a matter of how fast you need to charge the battery. 

  • If you know the battery is charged and in good shape use the 2 Amp setting.
  • If you are charging a large deep cycle battery or more than one battery than use 4 Amp setting.
  • You will probably use the wet/AGM/sealed selection most of the time. Use the Odyssey selection on all named Odyssey batteries at the 8 Amp setting. 


  • Guaranteed to never overcharge/undercharge between temperature extremes considered safe to charge or maintain by major battery manufacturers.
  • Push-button Selection for ALL battery types and charge rates.
  • 100% Full - Time U.S. Patented Pulse-type Desulfation keeps Lead Acid battery free of sulfate or dissolves sulfate completely in older batteries.
  • Detects and rejects batteries with bad cells.
  • Maximize battery life and capacity, recovers weak batteries.
  • Diagnoses battery’s condition / state-of-charge.
  • Recovers weak or deeply discharged batteries: including but not limited to flooded filler cap, maintenance-free, valve regulated lead-acid (VRLA), sealed lead-acid (SLA), starter, deep cycle and hybrid.
  • Maintain up to 8 batteries at a time. (requires BatteryMINDer® Y-Connector Accessory(s) 210-AY).
  • Auto-Restart after power failure.
  • Bad cell detection with auto-shutdown.
  • Includes Short circuit, spark, reverse polarity protection, thermal runaway protection, automatic D/C disconnect on A/C failure and quick-connect/disconnect fused alligator clip assembly.
  • Very high efficiency. California CEC Approved.
  • Automatically detects input AC power.
  • ECO-mode with hi-efficiency / low power consumption.
  • Ambient temperature compensation. Built-in temperature sensor automatically adjusts charge rate to ensure full-charge between temperature extremes considered safe to charge or maintain by major battery manufacturers.
  • 18 LED indicators show state-of-charge and important status mode / battery condition.
  • Rugged, vibration-resistant construction.
  • Never connect two or more batteries together before fully charging each and checking their condition. Failure to fully charge each battery and check their condition can result in a serious safety hazard.
  • Not for nickel–cadmium (NiCad), nickel–metal hydride (NiMH) or aircraft batteries.

Product Reviews

  1. Quick shipping

    Posted by Working man on 13th Sep 2017

    I've only had this unit a week and our power went out. It was nice to see it power up where it was set at. Resetting a battery charger is something you forget about after a power failure.
    Sad to say it was unable to revitalize our neglected battery. Not the charges fault.

  2. Replacement for Model 12248

    Posted by Jim Bass on 19th Aug 2017

    At the end of the day, it appears that the problem was more with the timer used to reset the battery minder. Expensive lesson, but the product is excellent.

  3. So far, so good.

    Posted by LD100 on 10th Aug 2017

    Following some health problems, I had to retire and now my car sits in the garage on most days.

    During a cold winter day it started but it sure didn't want to. The battery is over three years old and if I was still working I would replaced it, although it's quite a pain since it's stuffed under the fender.

    So I decided to get a battery maintainer first and see if I can get another year out of it if I keep it charged.
    I had four manufacturers of maintainer/desulfators to choose from and decided on VDC electronics BatteryMINDer.

    So far, so good, for maintaining , you just connect it. It does everything else. Whether or not I get an extra year or so we shall just have to wait and see, but this is obviously much better for the battery to be maintained than to leave it sit in the car being drained by the car's computer and other parasitic loads.

    Why did I choose BatterMINDer over one of the other manufacturers you ask?
    1. Features
    2. Warranty

    This model has specific voltage/amp settings for AGM and Odyssey/PLT batteries. The display of LEDs gives you required information but unlike a competitors that uses a "prettier" display, if their display fails you can't use their maintainer.

    As I said, time will tell if I made the right choice, but right now I'm feeling pretty good I have not got any complaints except for the shipping department at VDC...they put the BatteryMINDer and the voltmeter loose in the shipping box so that upon arrival at my house, the BatteryMINDer had come out of its packaging and was bouncing around in the box. Really, some old crumpled news paper would have gone a long way at protecting the equipment during shipping. I'm not asking for Styrofoam peanuts or those puffy bags but at least something so that the product doesn't bounce from one end of the shipping box to the other. Fortunately, it doesn't appear any damage was done. But you can't be lucky all the time.

  4. A must have Battery Charger.

    Posted by Richard on 8th Nov 2016

    The BatteryMinder 128 CEC1 12v is by far the best battery charger on the market for the price. It was used to bring back Two large battery's to full charge which are used to start a Diesel Motor home saving the expense of new Batteries.

  5. had an earlier model...this new unit has a few more bells and whistles, and it is working perfectly

    Posted by Unknown on 21st Oct 2016

    I use this instead of a converter, in my RV...batteries are charging or on float when ever I am plugged into AC. Have used this or your former production for 6 yrs with no problems...

  6. Nice product, works sell.

    Posted by Daniel Shanahan on 5th Aug 2016

    It brought a mostly discharged battery to full voltage overnight, and is still desulfating it. I'll know more in a few months, but several others have said they are pleased with their Battery Minder.
