DieHard 71345 Platinum Battery Maintainer Review

That sucks! Don't buy this. I bought it at the end of May 2020. Only used a few times and already broken. Don't waste money on it.

Compared to other chargers similar to the ones I've had, this is very disappointing, I've never been able to start a nearly dead battery although mine old units handle it.

I was disappointed with this charger. It's much easier to maintain and simpler than I expected. My old die hard charger that eventually gave up was a much more durable device with plenty of starting power as opposed to this one. I wouldn't buy it again.

I bought this charger with boost function to replace the old broken one on the farm. I mainly use it to start a big John Deere snow clearing tractor on cold days. The boost works very well, especially when turning on the glow plug on the 6-cylinder diesel engine.

In start mode, the voltage should quickly rise to 250A. These are also the duty cycles of the current applied. Even in Boost 50A mode it does the same. "rDY" was displayed all the time in Run mode. Didn't show any voltage except in charge mode. It's too slow for my use. I run a generator for electricity. I will not run 20 hours!

It's a huge piece of crap that keeps turning off and after a few months I had it. I have yet to get it working properly. Trying to talk to DieHard about support gets nowhere. Every number I call they tell me I'm calling the wrong place and they give me another number to call. An endless carousel of calls with zero results. I honestly think they sold me a crappy income with no support. SAVE MONEY and skip this product!

The grip and display are poorly designed, not what you would expect from a reliable $200 charger. The device should have reverse polarity protection, but it doesn't work. When I put it in boost mode it never applied power to the 10 volt battery, the fan turned on but I held a voltmeter to it and it never started charging. I read and followed the instructions but it just didn't do what it said it would do. I never tried the boost start feature, I learned enough just trying to charge the battery.

Comes in standard packaging, works as expected. After taking the product out of the box, I found that the plastic handle and cable management are of poor design. They work, but the grip is what you'd expect from plastic. Not much better than the one your kid pulls out on their wheeled backpack. I expect more than that from this company and also the price. Second, there is a plastic "plate" on the front that houses the buttons, which is glued to the top for alignment of the buttons etc. This…
