Simply AMAZING!: Tools & Equipment

My 2005 6.0 diesel has hardly been driven, it has 2 almost new batteries. Turn on this charger. Read 34%, I was like I knew! When running, I read no more than 13.4 volts. I let it run for about 35 minutes, both batteries were NEW again! This is the best charger I have ever used and very simple! A bad truck alternator now lasts much longer! 1 MUST HAVE!

Pros
  • Great for me
Cons
  • Some faults

Extremely reliable

This is my third. Bought it for the first time a few years ago, it worked almost all the time to hold the battery in my truck carpet cleaner. It was turned on and off multiple times a day. When he wasn't in the truck, he loaded my bike. I bought two more. One for my bike and one for my neighbor's bike. He borrowed mine a lot so I just bought him his own lol. I recommend to everyone. It also loads pretty quickly.

Pros
  • All right!
Cons
  • Brief instructions

Thinking about buying another one

Simple, lightweight, great value and works exactly as advertised. I bought this for my motorcycle battery when storing it over the winter. It detects the condition of the battery and charges accordingly. In my case my battery was half dead and I had no juice to start my bike. When it first connected, it noticed its condition and began charging quickly. After a few hours, the battery was charged and the charger automatically switched to service mode. I really like this product. It also worksโ€ฆ

Pros
  • Great for a small home
Cons
  • Definitely a bad product

One major downside - tools and equipment

This battery holder works. To be honest I can't say it works perfectly because as a maintainer I don't leave it enabled because that's not how I use them. If you're like me and don't believe he won't burn down your house or melt your battery in a puddle of molten lead and acid, you know this. Every time you unplug him, you'll have to tell him what your battery's chemistry is. You want to put it in your boat for the winter, leave everything packed up, and only turn it on four or five hours aโ€ฆ

Pros
  • Good product for the price
Cons
  • Long delivery time

Worked once then drained my new battery

I hooked this up to a brand new 12v battery. lead-acid battery. He charged it and a few days later I found that the new battery was dead and the charger wouldn't charge it. I tried the charger with another battery and it didn't charge that battery either. This led to me finding a 40 year old Schumacher charger in the attic that my father gave me. I cleaned it, plugged it in and it charged both batteries perfectly. Amazing that you have to resort to antiques to charge a simple battery. It isโ€ฆ

Pros
  • This is amazing
Cons
  • Everything is fine

I bought this charger for battery maintenance on a collector car in my garage. It turns out that it is completely useless for this purpose. When you turn on the charger for the first time, you must manually select the battery type (lead-acid or lithium-ion) before it starts charging/service. In the event of a power failure, the charger will reset and battery operation will be suspended until you manually reset the battery type. If you don't know the power is out, you can go back and find a dead

Pros
  • Easy to use
Cons
  • There are cons

Charger EZPZ with a banner!

I am a retired auto mechanic with a lot of experience with chargers. Received this today to replace Die Hard #71239 which is made by Schumacher and is identical to this SP1297 except it is red and Die Hard is black. A beautiful digital display banner guides you through connecting and charging. Reads the battery level and once fully charged, the device will enter auto-float mode and the device's green light will flash slowly to indicate it is in "maintenance mode". I've had the Die Hard modelโ€ฆ

Pros
  • Slim design
Cons
  • ---

Schumacher SP1297 The best charger repair shop I have ever had.

In Master's Charger World, it's Cat Meow. I need a 3 amp charger so I can use it on my lawn mower, truck and tractor battery. Also, I didn't need a 6V charger, so I chose this one because it can charge 12V lead-acid, gel, and li-ion batteries. This charger will display the current battery level in % and then proceed to charge and display the % of battery level in real time! When the battery level reaches 100%, the charger will stop charging and automatically enter auto maintenance mode andโ€ฆ

Pros
  • A Sea of Positive Emotions
Cons
  • No show

Useless as a battery holder!

The statement "plug and forget" printed on the packaging is completely wrong. In fact, if you really want to "plug and forget," buy a spare battery. Why? Because this charger is not a real battery. When you connect it to a battery and plug it in, the first thing it does is ask what type of battery you want to charge. As soon as you have made a selection, the battery will be charged. The problem is that as soon as the charger loses charge for even a moment, it forgets which battery you chose and

Pros
  • handy article
Cons
  • so far, so good
