Product Description

Amazon.com Product Description

The Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer is a unique AC powered automatic charging accessory for use with everything from smaller batteries designed for motorcycles, tractors and mowers, to standard car / truck batteries and marine / deep cycle batteries. Designed around an internal microprocessor which constantly collects information from the battery that the unit is attached to, the SEM-1562A effortlessly and quickly ensures that your 6 and 12-volt batteries are maintained at optimal levels, and does so in the fastest and most convenient means possible.

An easy to monitor control panel makes charging effortless.

Microprocessor Controlled Charging for 6 and 12 Volt Batteries

Microprocessor controlled charging and maintenance is simply the easiest way to keep batteries at optimal power levels. This convenience and speed is experienced from the moment that the SEM-1562A is connected. First, the unit utilizes the user's choice of either easy-to-connect and remove battery clips, or permanent ring terminals (both included), each of which allows for charging or maintaining of batteries whether they be in or out of vehicles. The SEM-1562A also features automatic voltage detection which allows it to automatically determine whether the connected cell is a 6-volt battery or a 12-volt variety. This eliminates the possibility of damaging a battery due to choosing the wrong charging settings. Once your battery type has been identifified, a multi-phase charging process kicks in which plays out via the unit's automatic Charge / Maintain modes. Tipped off by the data analyzed by the onboard microprocessor, your battery is supplied with a constant charge until it reaches a preset level - at which point charging ceases. Eventually, if the charge falls below a certain level the SEM-1562A automatically transitions into Maintain Mode, delivering a small, safe charge that will raise the battery's level back to where it should be.

Fast recharging of multiple battery types and sizes (50% depletion assumed).

Ease of use both in or away from your vehicle.

In addition, because of the constant monitoring the battery, the SEM-1562A can react to charging needs swiftly, efficiently and accurately, allowing charging cycles to click on and off in the same way. Because of this, batteries can be left attached to the SEM-1562A indefinately for storage without the risk of overcharging and/or damage. Additional features include: automatic temperature compensation which adjusts the maximum charge voltage and maximum maintain voltage based on the ambient air temperature; thermal runaway, which automatically reduces the current if it detects the battery may be getting too hot; an auto-start feature that keeps power from flowing unless a proper connection exists, or in the case of a reverse hook-up; and a Desulphation mode for charging batteries left discharged for an extended period of time.

5.0 out of 5 stars Great charger but better deal is waiting for you, December 17, 2007

This is a great charger but the same company (schumacher's battery maintainer), makes an identical product for sears, branded as diehard.
It costs the same as on amazon but comes with a 3 year warranty, not the standard 1 yr. warranty found here. Plus you don't have to deal with shipping hassles when you can just go to your local sears and pick one up or exchange if you have problems.

This review is from: Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer (Automotive)

After having the battery on my "summer only" convertible go
flat last winter I decided to invest in a battery maintainer.
The Schumacher SEM-1652A was the best compromise of price (around
$40 with shipping), features (a normal charging rate, and a
lower maintaining rate, with overcharge protection and indicator
lights), and small size (fits easily under the hood by the
master cylinder, battery wiring adaptor with quick connect makes installation and removal a snap.
I'd add a few extra crimp-on terminals of various ring sizes to the kit,
so different power connections with the wiring adaptor could be made
(my car has the battery mounted in the front fender well, I had to get
larger ring terminals to go on the remote jump starting terminals
under the hood.

Update: I bought a wattmeter to measure the power use of a fridge ( seemed to be running more than
normal, we replaced it with an energy star rated model ) so I hooked up the Schumacher maintainer
to the meter to see what it drew when it was trickle charging / maintaining. Charging was .25 amps or about
30 watts per hour, and maintaining was .11 amps or about 13 watts per hour. Pretty low energy use in my book.

3.0 out of 5 stars Don't use for deep cycle batteries, November 30, 2009

This review is from: Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer (Automotive)

Bought this charger to charge/maintain my deep cycle battery used for emergency power outages. The manual included with this charger even describes it charging deep cycle batteries and gives a charging estimate of ~36hrs. Fine for what I'm looking for. The charger repeatedly aborted the charge on my brand-new battery. Their customer service tech said it wasn't meant to charge deep cycle batteries due to the higher internal resistance. This should have been made more clear in the packaging, labelling and product description. I've lost time and money. Now I have to go buy a 'real' charger...

Update - The charger was actually DOA. I returned it and replaced the charger with a new one on an auto-shop recommendation. It is working fine. Schumacher didn't want to own up to a bum charger when I called them earlier.
