Customer Reviews
I did a bit of research before purchasing this product. If you want a quick charge, I have read that your battery won't last as long. For battery life, the ideal charge is low amerage. I appreciate that this charger provides a low amp charge to the battery. I had an older battery charger that I believe prematurely destroyed one of my 12v batteries, so I did my best to find the best value replacement. As a matter of fact, the way I saw the older charger behaving (according to my digital multimeter), I was concerned that it could cause the battery to explode or start a fire. I decided to get a new one. I looked at all of the battery chargers I could find on Amazon and other sites. Eventually, I settled on this particular model for these reasons:
1. Provides a low amperage charge, which is supposed to help prolong battery life.
2. Desulphination mode, which is supposed to help prolong battery life.
3. Safety shutoff features, so that it doesn't overcharge the battery.
4. Reads the battery polarity and illuminates a red light if you have it reversed.
5. Excellent review on Amazon and other sites that sell battery chargers.
I've only been using the battery minder for a couple of months, but I think it is working well. The recharges and maintenance modes seem appropriate. The batteries seem to last a long time after I charge them. This product seems to be living up to the claims and ratings. I am impressed.
I've been using the small BatteryMinders (the 1.3 Amp maintainers) for the past few years and decided that for some of my larger batteries, especially the deep cycle setup used in conjunction with a set of solar panels, that I needed something that was capable of pushing much more than 1.3 Amps. Enter this product with its 2 / 4 / 8 Amp settings and the ability to automatically reduce the Amp "push" and start cycling the battery (or in my case batteries, as I have 4 large deep cycle batteries connected in parallel) with a maintenance charge.
So far I've been very happy with this product as I have been with the 1.3 Amp BatteryMinder in the past. The construction is solid, a direct-wire connector is included, the ability to connect directly with included clips is great, and there isn't that "it's going to break next week" cheap feel that some of the other competing products have (I bought a used bike and a competing product came with it - now it is hooked up to a BatterMinder and the other charger is sitting in a box).
If you have need to keep a large battery or bank of batteries well maintained and on a steady charge, be they for your trolling motor or a battery backup for your sump pump (because the power always seems to fail during a rain storm just when you need that pump most), I strongly recommend this product.
I installed this for my 4 very large house batteries on my RV. Since it cost about $1800 dollars to replace those batteries I am interested in getting as long a life as possible. It has been in place for about 2 weeks and so far it is doing what I expected. The batteries hold a charge longer than before. This type of battery in Arizona normally lasts about 4 years, and this set is 18 months old and beginning to show its age. But with this device installed they are back to about 95% of what they were when they were new. My only complaint is about the temperature sensor that can be used with the unit, it does not come with the device, but is an extra cost option. I think it should be included since it provides a feature of the device.
