DieHard Platinum 6V/12V Battery Charger and Maintainer

Works great on my Lincoln LS

Have it on my LS that sits most of the time with a 12 year old battery

Good as a maintainer for medium to large batteries

When I first tried this charger/maintainer on my 04 nissan maxima, I just wanted to basically top off the battery. I plugged it in and it displayed the battery was at 96% charge. I left the the Diehard connected for 4 hours and noticed that the level did not increase. After checking the manual, it states that it can only charge batteries up to 550 CCA. My battery had 650 cold cranking amps. So basically, the 3 amps was just enough to maintain it's current charge level. I was hoping that this would be a good slow charger. I have not been able to try it as a charger but good as a battery maintainer. I like the 3 provided options to hook it up to the car...via clamps, O ring connectors for a semi/permanent connection(pig tail at the other end that easily connects to the charger/maintainer), and cigarette connector.. It does have a solid feel to it. I also like the led display, stating the status. I bought it during a last minute Chrirstmas sale for $24.99

Fix my battery Issues

This was exactly what I have been looking for, I have an SUV and several added electronics and my battery would lose its charge but now it is always maintained ..

Great Maintainer!

A very nifty unit. Excellent display. Nice that it handles both 6V and 12V.

High Quality Product at a Fair Price.

The product is VERY easy to use - no need to be a mechanic to use the product. The charge time is very quick and the digital read out makes battery charging easy. High quality product. Very easy to buy the product with the "order on line and pick up at store" program.

Like it

I like the way it shows percentage charged and the speed of charging.

Nice

Does what its suppose to do.

Works Great

Great at maintaining and/or charging any AGM, deep cycle or conventional battery. The 6v option is nice too for the old bikes too

What a charge!

Very easy to use and keeps me from replacing the car battery so soon.

Simple and effective

I have used this charger several times on 12V batteries installed in and outside of the car. Easy to connect, charger does the rest.

Excellent and practically fool-proof

I like that this comes with three ways to connect to the vehicle battery: old-fashioned compression clamps for direct connecting to a battery, terminals that I connected to my motorcycle battery, and cigarette lighter style power adapter connector that doesn't even require the hood to be raised! Also like the diagnostic readout that displays current level of charge as percentage charged, gives an idea of how 'bad off' the charge is. Cables are fairly long also. I got this on sale for twenty two dollars which helped justify since I already had the 2/10/50 amp model but needed something to maintain mower and motorcycle batteries.

Alternative to BatteryMINDer 12117 and CTEK Multi US 3300

I also own a BatteryMINDer 12117 and CTEK Multi US 3300. The DieHard unit is the least expensive of the lot and yet comes complete with a cigarette outlet connector (which the others do not). The unit has a rugged feel to it and even the battery clamps appear to be heavy duty. On the con side, the quick-disconnect ends would not mate flush on mine (quality control problem?). Also, it is the least well documented of the lot. Anyone who might want one of these gadgets would probably appreciate some technical details. For example, the instruction booklet has no mention of the AGM type batteries which probably means it's not for OPTIMA and other gel cell batteries. However, those with run-of-the-mill batteries who want simplicity, the DieHard unit is almost perfect.

Nice features, easy to use

Automatically adjusts to the right settings, switches to trickle charge when needed, and displays the % charge of the battery.Includes strong clamps, terminal mount adapter, and lighter socket plug which are all easily changed.Compact, lightweight, and built-in hanger.

Worth every bit the money

It worked perfectly...I had a riding lawn mower battery that had died, and it recharged it with no problem. I would highly recommend this product.

Great Product!

Best I have seen

Great Product- I purchased one and returned to buy another one, I use them on water craft, but great for other vheicle to keep battery at it best.

Best Battery Maintainer Out There

The display on this is the best. I just purchased another brand a year ago and replaced with this one. Great options, love the display.
