Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer

I use this model on all of my vehicles including my tractor and they work perfectly. Since purchasing these units I have not had to buy any new batteries. They are a great product and a great value. The price I found for these at Amazon.com was less than I could buy them for locally.

Worked great right out of the box.  Absolutely no issues so far.  Smaller and much easier to use that the older style of 8-10 amp chargers.  I would recommend this one and I am a pretty good mechanic.  I own a heavier chargers for when batteries go dead from open doors on the cars, etc.  However for bringing your battery up, or leaving it plugged in and charging to maintain the batteries, this unit is excellent, especially for those with bigger trucks that have 2 batteries.

This is a very rugged looking unit which has worked very well so far. The 6 amp capability is a bonus for a battery maintainer.

This is a great tool to save time driving to a parts store for basically the same test they'd perform. But you still really need a load tester to truly diagnose a "dead" battery (I bought the old school Schumacher). It will tell you the current charge state which is what I bought it for.

This charger/maintainer may work as a maintainer but I wouldn't recommend it as a charger because it is very slow.  1.5 amps should be enough to charge a battery but the way this one is designed, it will take forever to charge a battery that is only slighty discharged.  I put it on a battery that was discharged enough that one of my other 1.5 amp charger/maintainers would charge it steady.  This unit however constantly turns on and off as it is charging.  I put it on the battery for 24 hours and it was still turning on and off.  I then put one of my other charger/maintainers on the same battery and overnight, the battery was fully charged.  Then I put this unit back on and finally the light stayed on indicating full.  If I turned the car lights on, the charger would begin clicking on/off again but soon after turning the lights back off, the charger's light went back to steady on.  So I think it works as a maintainer but I wouldn't rely on it to charge.  I called customer service to see if the unit should always turn off and on and sent an email.  The email reply said the unit shouldn't work that way and I should call customer support.  The customer support person had to ask someone but came back and said that is the way it should work.  On the other hand, when he asked what ends I used, I told him the alligator clips to which he replied, make sure I have them secure in the 110 outlet.

This charger / maintainer lives up to my expectations and performs as advertised by the manufacturer.  Out of all the units I looked at this one states that it will charge sealed and AGM batteries.

I purchased my unit from the distributor directly in Bradenton fl...they got it to me fast because I needed it promptly. I used this unit the program two BMW ABS MODULES, one JAGUAR SEAT MODULE...The unit maintained the needed voltage required to carry out the procedure. At times the voltage read 14.2-14.6, and on the lower side 13.58 because the radio and park light were on...I am very satisfied with the unit and recommend it to anybody that flashes, encodes, or codes vehicles...I have had mine now about 3 months and I have no complaints....if you need more info call Graham directly in Bradenton at Powermax and he can help...

I went for this slightly higher priced unit to get the automated 10 second test time and Digital read-out. Works pretty well. Buy this before you buy a battery or charger you muy not need. Use the handle the back/bottom gets hot. Let it cool before storing it away. The battery clamps should be a heavier gauge, I had to straighten mine. I've been sold on the brand for years. I have a Schumacher Charger/Starter over 25 years old a bit worn but still working.

Good charger to maintain your battery in storage. I have three of these on various cars that are in storage. It will keep the battery topped off just fine.  I would not rely on this charger for a fully discharged battery.

Using this battery in child's electric car which runs at about 7-10 amps @12V.  It works great. I use Schumacher Model# SEM-1562A to charge it. This battery is inexpensive and has higher capacity vs the original battery. It's gone through many charge cycles and is still working great...The secret to battery longevity is not to let the battery run to zero volts by frequently charging it.

Very good product. Purchased it to replace a 14.4 battery. This charger replaces several different voltage chargers for Skil products.
I'd recommend this product.

Smartest tender/ charger I've ever used and cheap too! Active monitoring charges intermittently as the battery can accept current and actually shuts off when the battery is "full" so you don't boil off electrolyte or warp plates. MOST important is that it will take a good battery to 13.2 volts where they should be. Every other charger I have, fancy or plain, only gets to about 12.6V

A word of caution, make sure you're buying THIS charger. Schumacher makes an identical looking unit (in the same case, different stickers) that isn't smart and doesn't reach the 13.2 volt charge necessary for optimal battery life.

excellent charger, no complaints and as far as I can tell it even chargers at 3.0 speeds. it charges a dead battery before I have a chance to discharge a full battery with heavy use

Like having these small chargers for charging and maintaining batteries. What I really like about this maintainer is it works on 6 volt and 12 volt automatically enabling me to move it from vehicle to vehicle.

Mounted this on a golf cart I converted from Lead Acid to Lithium battery.  I had no 12 volt power with the new battery and no previously mounted converter.  Has been working well powering lights but no heavy loads as of yet.

I love how it maintains the charge.  I come home from a day at the lake, put it on the charger, and it knows when to switch over to a maintain mode instead of full blown charge.  If you don't have one of these for your boat, you're wasting your time with chargers the night before.

i keep this trickle charger attached to my automobile battery when the vehicle is parked at home.  i leave it outdoors and forget about it, except to check the voltage in the battery once in a while.  it maintains the battery at 13.32 volts constantly and is ready to go when i am.  i do not drive very often, maybe once a month, so this device is ideal to maintain the charge in the battery.
