BatteryMINDer® Model 2012-AGM : 12V 2 AMP Charger-Maintainer-Desulfator For Optima, Odyssey, Polaris, Yuasa & Other High Performance Specialty 12 Volt Sealed AGM Lead-Acid Batteries (Worldwide Usage)

In Stock
BatteryMINDer® 2012-AGM is a SmarTECHnology™ microprocessor controlled charger/maintainer/desulfator for Optima, Odyssey, Polaris, Yuasa & Other High Performance Specialty 12 Volt Sealed AGM Lead-Acid Batteries . Plug 'n Run feature means "no buttons to push." It is designed with 7-stages and is fully automatic. This charger actively monitors your battery's voltage, amperage acceptance and temperature at all times. Features easily understood diagnostic LED indicators that display the battery's condition and actual state-of-charge profile. Working through a series of charging and diagnostics stages, the internal program adjusts its output several times a second based on sensor reading to quickly and correctly charge your battery. When used as a maintainer, the BatteryMINDer® is guaranteed to maximize your battery's life and storage capacity. The temperature compensated long-term maintenance stage will add years of service. Patented full-time high frequency pulse desulfation (NOT high voltage) prevents battery sulfation on new batteries or eliminates in older batteries, the #1 cause of early battery failure. Unit can maintain up to six 12 Volt batteries at one time when connected in parallel by using SmarTechnology™ Y-Connectors 210AY or customer supplied 18-Gauge insulated wire.

Product Description

Features & Benefits:  
BatteryMINDer® Model 2012-AGM: 12-Volt 2 AMP Charger-Maintainer-Desulfator for Optima, Odyssey, Polaris, Yuasa & other High Performance Specialty 12 Volt Sealed AGM Lead-Acid Batteries

  • Designed for High-Performance Specialty AGM Sealed Batteries (such as those made by Optima, Odyseey, Polaris & Yuasa.
  • Guaranteed to never overcharge, regardless of how long connected.
  • Temperature compensation ensures proper charge in hot or cold environments.
  • Installed ambient temperature sensor for 0°F–130°F operating range ensures the battery will never be overcharged or undercharged regardless of temperature extremes. Optional "at the battery" sensor is also available for greater accuracy when battery and charger are not in same ambient temperature environment.
  • Diagnostic LED indicators for power, polarity reversal, battery weak, load, bad cell, testing, desulfating, temperature compensation, charging stage and charge level.
  • Maximizes battery life and capacity, reconditions weak batteries.
  • Automatic high frequency (not high voltage) pulse desulfation (U.S. patented.)
  • Plug 'n Run operation-no buttons to push.
  • Microprocessor controlled ensures accurate-precise charging and maintenance during entire lifetime of unit.
  • Maintains up to six batteries at a time (6 or 12 Volt batteries connected in parallel) Requires use of Y-Connectors 210AY (sold separately) or customer supplied 18-Gauge insulated wire2.
  • FCC certified.
  • Extremely efficient, low operating costs.
  • Automatic disconnect and resume if AC power is interrupted.
  • Short circuit, spark, polarity and thermal runaway protection.
  • Built-in Battery Condition Indicator.
  • Worldwide 100-240 VAC 50/60 Hz input.
  • 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 use with aircraft batteries. For information about BatteryMINDers designed for use with aircraft batteries, see our Aviation Application page.
  • IMPORTANT INFORMATION ON USING PRODUCT OUTDOORS: Always mount units in vertical position with cord sets exiting downward to ensure weather tight integrity. Unit must be mounted this way to ensure long term trouble-free life including weatherproof integrity. Mounting in any other manner or using unmounted (parallel to ground) except indoors may cause unit to fail due to water intrusion that is unable to drain correctly to avoid damage.
  • BatteryMINDer® Model 2012-AGM is precision set for Specialty AGM batteries including but not limited to: Optima and Odyssey. Not for use with non-AGM batteries.

Product Reviews

  1. Great battery charger

    Posted by Fca450 on 31st Jul 2017

    The one I had didnt work well with agm batteries, so i bought this one and is workinh really good

  2. Great charger at a good price

    Posted by Unknown on 8th Mar 2017

    I replaced an older model with the new 2012-agm. My Prius has a agm battery and I do not drive a lot. The charger is completely automatic. I just plug it in and let it do it's job. Great Charger.

  3. Great Value

    Posted by Thomas Axel on 20th Sep 2016

    Plug and play. Cannot get any easier or better to keep AGM batteries up and desulfated.t

  4. Great battery tender

    Posted by Unknown on 7th Sep 2016

    very nice charger that is idiot proof as far as hookup. came with generous accessories for battery hookup.Gives good info while battery is charging. works well and is maintaining my 3 AGM batteries as we speak

  5. Can-Am Spyder AGM maint

    Posted by AncientMariner on 21st Sep 2015

    Product installed easily. However, polarity markings on temperature sensor connectors are difficult to see and not even mentioned in shipping documentation. I recommended to my sister that she use nail polish to mark polarity. Better would be a polarized plug that can't be misconnected.

  6. 2012 AGM

    Posted by Unknown on 9th Sep 2015

    This is my second 2012 AGM, they are used on two limited use BMWs (the replacement batteries are $400+). I have used the 1st 2012 AGM for over 3 years and have not experienced a battery failure issue.
    Great product for the price, I would recommend this to anyone for a limited use vehicle.

  7. 2012-AGM on a 18Ah

    Posted by William P. Turczynski on 18th Jul 2015

    Easy Plug&Play setup. An old 18 Ah battery that was down to 75% capacity has shown 3-6% gain in the first three days of charging. This is going to be a good test for this charger.

  8. Works as advertised.

    Posted by Dave on 8th Jul 2015

    The test will be how long the car batttery lasts (original Saab battery lasted 5 yrs. 3 months with no BatteryMinder) and how long the BatteryMinder lasts.

  9. Top quality

    Posted by mustang_309 on 28th Feb 2015

    Works as advertised. only drawback is it would be nice if the charge cord were a couple feet longer.
