Review: This is a simple to use unit, that seems to work well. I have used it for several weeks now. It is too early to say how long a battery maintained by this unit will last over one that is not maintained. Of course, if I didn't have a problem with such a battery in the first place, I wouldn't have gone to the expense of getting one. We have one automobile that is driven infrequently and for which I have replaced a battery once a year for the past four or five years. I used to keep a charger on that battery, but I suspect that I was contributing to the problem of building up lead sulfate crystals (sulfated battery) by doing so. So on the advice of a reputable shop, I switched to this battery minder. Though that shop did not recommend a specific model or manufacturer, they did emphasize getting a "good one." After reading reviews, I chose this model. So far, so good. I really liked the fact that the unit came with temperature sensors for charge and cycle regulation, though this auto in question is garaged and doesn't see extreme temperatures in this climate. But most of all, I liked the extra cables provided so that one could use the big alligator clamps or hard wire the connections to the battery with the additional provided cabling. I hard wired it to the battery and just leave the pigtail sticking out so that the unit can be reconnected after the car is used and disconnected before use quickly and conveniently. I am seriously considering getting another unit for my garden tractor/lawn mower. Update November 6, 2022: On October 20, 2022, I discovered that the BatteryMiNDer 2012 had failed. I usually glance at the unit every morning when I walk out to get the paper. On that morning, I noticed all lights on the unit were off. I checked the power cable and found that no matter what or where it was plugged, the power light would not come on, and that the unit was inop as measured with my volt-ohm meter. The unit had been in service in my garage protected from the weather since it was first put into service on August 15, 2022. The unit works very well and with that I am pleased. I have never attempted to start the car with the unit attached, btw, so that was not the cause of the failure of the original unit. The unit failed after about 2 months in service. I called the company on their 800 number, spoke to a man named "Dave," who said that there may have been a power surge (I doubt it as nothing in my home or garage else was affected). He issued a RMA number and instructed me to return the unit at my expense. Since I still had the original packaging, I repacked the unit with all the cables and accessories and took it to the Post Office on Oct 21 (USPS $12.50 to Huntington, NY). It was received at VDC Electronics on Oct 24th. I received notice that the unit was inop (Surprise! Surprise!) and would be replaced without charge. A brand new unit was shipped to me on Oct 26th from their NJ warehouse. I received it Friday evening Oct 28 at 7PM by UPS. I put it immediately into service once again, taking care again to save the original packaging just in case. All in all, great customer service. No complaints. ## Features - EXTENDED BATTERY LIFE - Automatic full time desulfator reverses sulfation (a buildup of lead sulfate crystals) the primary cause of early battery failure by using a patented range of high frequency pulse desulfation (not high voltage) to safely remove sulfation and recondition weak batteries. Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition. Extending battery life up to four times when compared to new batteries not being properly maintained - AMBIENT TEMPERATURE SENSOR – Installed temperature compensation precisely adjusts battery voltage based on temperature sensor readings. This ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. Reverse polarity, short-circuit and over temperature protection. - SIX BATTERIES AT A TIME - Maintains up to six batteries at a time when connected in parallel. Requires the use of Y-Connectors 210AY (sold separately). Ideal for winterizing Cars, Trucks, Motorcycles, ATV, Boat, RV, etc. Worldwide 100-240 VAC 50/60 Hz input. - INCLUDES – Included in the box is Model 2012, an installed Ambient Temperature Sensor, 2’ Battery Clip Cord with Quick Connector, 2’ Fused Ring Terminal, & a 6’ AC and 6’ DC cord. - FCC CERTIFIED - Certified by the California Energy Commission as meeting the current efficiency standards which means it meets strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005EKY1EM | | Amperage | 2 Amps | | Best Sellers Rank | #20,062 in Automotive ( See Top 100 in Automotive ) #138 in Battery Chargers | | Brand | BatteryMINDer | | Customer Reviews | 4.7 4.7 out of 5 stars (1,011) | | Date First Available | July 27, 2011 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.8 pounds | | Item model number | 2012 | | Manufacturer | BatteryMINDer | | Manufacturer Part Number | 2012 | | Product Dimensions | 9 x 3 x 10 inches | | Voltage | 12 Volts | ## Product Details - **Brand:** BatteryMINDer - **Colour:** Black, Red - **Item weight:** 1.8 Pounds - **Output voltage:** 12 Volts (DC) - **Product dimensions:** 7.6D x 22.9W x 25.4H centimetres ## Images ![BatteryMINDer 2012 Battery Charger by BatteryMINDer - Image 1](https://m.media-amazon.com/images/I/81W199qu0IL.jpg) ![BatteryMINDer 2012 Battery Charger by BatteryMINDer - Image 2](https://m.media-amazon.com/images/I/91BCzJtQL9L.jpg) ## Questions & Answers **Q: will this Battery charger/tender charge a dead battery or just maintain an already charged one?** A: Depends on the battery. If it is a large battery (ex. 110ah), then it will only maintain. If the battery is smaller (ex. 20ah), then the charger will charger it and maintain it. In regards to charging up a dead battery, again it depends on the battery and what the voltage is on the battery using a voltmeter. If the battery is too low, it may need to be charged up in parallel with another battery and charger. Feel free to call our free tech support for further questions, 866-668-3163. **Q: can a vehicle be periodically started with the minder hooked up to the battery and plugged into AC power ???** A: You probably could but why would you want to? Because the BatteryMinder has some pretty sensitive electronics to monitor the battery charge level and temperature, I would not recommend leaving it attached to the battery when you start the vehical... at least I wouldn't do that. **Q: not sure what this product is for is it only for reviving and desulfarating or is it also good for keeping a bettery afload for long peiods of time?** A: I have had batteries in sporadically/ rarely used vehicles and machines maintained with this brand of trickle charger regularly last 10, 12 years and longer, way beyond their projected 3-4 year life times. I almost believe batteries last indefinitely, as long as they are on this little charger. Can't recall one ever becoming unusable as long as they're on the charger continuously. Use them religiously on boat, 4 x 4's, truck, all batteries I have that work only occasionally. This thing has not let me down; quite the opposite. Great product, pays for itself over and over. Only caveat is, if power goes out and stays out unexpectedly, the little LED green light remains on and will slowly drain the battery over a long period of time. So as long as the charger is hooked up, it MUST have a stable, uninterrupted power supply. Also, if battery is too weak before first use, it won't help. Best for maintenance of decent battery, not restoration of one already bad. There is a critical voltage below which these chargers will not work. Hope this helps. **Q: My last batteryminder came with the quick disconnect plug/cable that is permanently attached to the battery, is it included in the pkg? thanks.** A: Yes, the quick disconnect is part of the charger and it comes with two attachments one with cable clamps and one with oring connectors for a permant type connection just like the picture. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***0 on 5 March 2025* It was as described. ### ⭐⭐⭐⭐⭐ Review *by J***K on 24 August 2022* This is a simple to use unit, that seems to work well.
