Don,t waste your money.

I got this battery charger for a birthday gift. The battery charger I had before for over twenty years was a Centuary. It cost around $100.00.I have used it this charger three times to charge up my diesel truck. Well the cabels touched Pos.& Neg. instint death to the charger. There is no circuit breaker on it if this happens. Spend a few dollars more get a centuary or shumaker.

limited usage

OK as a charger-as a starter not so much. I just now replaced the puny clamps that had started to rust. I find a portable stand alone jump starter more reliable.

Great back up

|

I use this charger regularly from May to October during our salt water boating season. We carry four extra, large batteries on our 30 year old boat. We use the backup batteries together with an inverter to run our computers, phone chargers, and my CPAP machine while we spend 3 or 4 days anchored up somewhere. This process leaves the boat batteries to run the boat appliances. Once we return to our boat slip we use the DieHard charger to recharge all.

Unreliable design

|

I am a highly experienced engineer, and I purchased one of these chargers. I only used it for about 8 times over a 2-year period. The last time it failed completely. When I dis-assembled it, I saw the five small transistors that produce the load current. One fails, and they all fail. I have no idea why it failed, as I was only trying to charge a small mower battery. There are no parts available, and I was denied Sears servicing of the item. There is no schematic or parts lists available.

I have had excellent lifetimes on my other past Sears products, but this one is terrible in every way except its looks.

If you do have one, treat it very carefully in every way is my only suggestion.

Very practical and helpful

|

I bought this battery charger for my husband car. he rarely used this car so whenever he needs it, it wont run cause its battery dies. this battery charger is very helpful and practical . its size is perfect.I think this kind of battery charger should be available in everyone's home as it is as important as an extinguisher.

Do Not Buy

|

Purchased this charger about a year ago, have used a few times. Last week I charged a battery overnight and simply unplugged the power cord and walked out of my garage for a few minutes. I came back in to a cloud of smoke coming from this charger and the positive and negative cables melted all the way into the unit. Serious fire hazard, this unit should be recalled. Worst unit I have ever owned and would not recommend buying one period.

First one didn't work

|

Brutal winter and the first one we bought didn't work.
Took it back and it was replaced quickly and the second one worked.
I guess I would recommend you check it before you leave the store.

Does a good job

|

Has worked perfect for a few months. Great to keep a battery maintained, its automatic. Unit has some weight to it, made at the same country Schumacher chargers are made. Charge dead batteries slow for best results.

Diehard 2/10/50 Amp Battery Charger

|

Solid built should last for years to come. Price was about 50% of what another high quality brand. I bought four of these one for me, one for my son and two to sell to pay for all four. I had a 2/10/50 Amp that I had for about 20 years that I sold also.
I like the 50 Amp start so you can start the car fast. I also like the automatic 10 amp changes to 2 amps once the batter is fully charges. Also like that it will fully charge a 12 volt car battery in 4 to 5 hours. These chargers are not needed all the time but when you need one they are great to have. I have let my neighbors use this charger and that make me a hero.
Overall I like these charger very much.
