FAQ about Sears Battery Charger

Is my battery due for replacement & can you explain my 12 volt (2-10-50 amp) charger's actions? the John Deere brand 42" lawn tractor is two years old, original battery. just got through a mild winter with no tractor activity since October. The battery is dead. Hooked it to a Sears 2-10-50 amp charger set at 10 for the last four hours. the needle started at about 11:45 if it were a clock face. Now it's at about 10:00. Is dead after this winter normal? It didn't happen last year. What should I expect the life of the battery to be? How should the needle behave if it was charging normally? Would I damage the charger or the battery if I move it to 50 amp setting and leavet their. That setting seems to be for Starting not charging and when I put the button on 50 the needle jumps over to about 2:00 (on a clock face). Thanksfor any info/advise that makes sense. I'm NOT an expert on batteries, after being in the electrical / electronic business for over 30 years, but, I can tell you 1 thing, a lead/ acid battery can " poop " out on you because of non-use. The way that this battery works is that the acid eats away at the plates and causes a chemical reaction that makes an electrical differentiation between the + and - side of the battery. If the battery is left to it's own device, it will eat it's self. When used the battery will use all of it's plates and poles, when not used it will erode the closest poles and give you a " dead cell ". Other than going out in the dead of winter and driving you lawnmower around, there is NO GOOD WAY, that I know of, to preserve your battery. The same thing happens if you let your car or truck sit for a few months, the battery would, simply " poop out " on you. You might try a solar, trickle charger, they let the battery stay heated, which is good. Other than that, expect to replace the " pain-in-the-butt " about every 2 years. Hope this helps, don't be dismayed, a lot of people have this same problem.

What is the best car battery charger to get? I have an old Sears 2/10 amp battery charger that is real old and in need of replacing. I cooked a lawn mower battery the other day because I left the charger on it too long, and figure it's time for one of the newer models that monitor the charge rate and taper off slowly and stop completely when it's fully charged. So what is the best type to get? I've read bad things about the Vector's, their clamps supposedly break easily. What else should I be looking at? This answer comes from an expert in both the automotive battery field and also the automotive charger field as well.
I realize many people answering will have their own opinions and guesses, as I've seen some wild guesses already.
One thing you should know here is that you don't have to spent over $50 for a GREAT BATTERY CHARGER!
Reason I say this is because my original SCHUMACHER FULLY AUTOMATIC ANALOG model battery charger model # SE-520MA is going on over 9 years old now after charging hundreds of my personal AGM batteries, and still works as good as DAY ONE! Great analog charger which I bought at WALMART for roughly $43 + tax.
Not bad at all considering DACOR DIVE CO wanted to charge me $180 for a 3-amp (hopefully fully automatic) charger in which to keep my DPV underwater dive vehicle AGM batteries fully charged. OUCH!
After testing that SE-520MA charger to factory AGM battery specs, it worked so perfectly as to the CYCLIC charging rate. PERFECT right on the money voltage wise! Still is today! Great charger! Both 2 amp & 10 amp rates plus a 3-way selector switch for all 3 types of batteries.
One position for FLOODED LEAD ACID batts on MANUAL mode, one position for FULLY AUTO mode AGM & GEL CELL batts, and one more position for FULLY AUTO mode DEEP CYCLE batts.
My original AGM type YUASA DPV scooter batteries are still factory fresh strong after some 9 years of use, so it pays to use a GREAT charger!! Fully automatic battery chargers are the only way to go if you want your batteries to last over many charge cycles!
Henry, who is now retired from SCHUMACHER, was terrific in going over the SE-520MA charger specs with me to assure me it would match my battery needs perfectly! Great engineer and can't say enough about him. He will be missed!
Steve, who now has taken over his place, is very knowledgeable also and knows the product line very well. We talk quite regularly on battery charger applications. I helped field test the newest SC-1200A mentioned below as to the computer ALGORITHM TWEAKS
So when SCHUMACHER was coming out with the newest (revamped second generation models) FULLY AUTOMATIC SPEED CHARGE series I had to have one of the SC-1200A models to test.
I was so pleased with the computer ALGORITHM that I only had a few minor inputs as to the ALGORITHM TWEAKS. Other then that it was almost a mirror image of my SE-520MA analog charger. Only better and computerized!
It has 3 selectable rates at 2-8-12 amps respectively. It has 3 types of batt selection as to FLOODED LEAD ACID, DEEP CYCLE, or AGM & GEL CELL.
One other great feature of the SC-1200A is that it checks the batt for any signs of early SULFACATION and runs it through a DESULFATION mode if the batt is questionable.
If the batt truly is bad it will fail it and end the charge test. I purposely tried a known bad AGM battery on it and it sure does work great! No other charger out there that I'm aware of has this feature!
I would also recommend first fully charging any/the intended battery, to be stored or FLOAT MAINT CHARGED, with a home/auto FULLY AUTOMATIC TYPE CHARGER similar to say a SCHUMACHER model# SE-520MA, or their newer SC-1200A FULLY AUTOMATIC SPEED CHARGE computerized switching type model.
The WALMART model # is WM-1200A and cost is roughly $42 + tax.
These are my 2 personal choices, which I use everyday to charge all my AGM type 12-volt batts that I use in my under-h2o diving equipment and AGM type batts I use for all my computer UPS units as well.
They both work flawless and to perfect battery specs I might add. I also use both chargers as well on all my other car/motorcycle type flooded lead acid batts because they are FULLY AUTOMATIC selectable type chargers for under $50.
WALMART, SEARS, and others sell the same or similar model # as well, as they are all made under the SCHUMACHER name. Price will be the cheapest no doubt at WALMART, as I seen it around $42 + tax.
I hope this helps everyone out to make a good choice when buying a great long term charger!
Thx for your time!

How do you know your car battery is charged using a Sears manual battery charger on 40 amps? It has a meter. What should the meter read when the charging is done? on the meter if the battery is good charging on 40 amps it should show lowest reading( this shows that the battery is not recieving a charge )
if it reads high the battery is either bad or not fully charged.
the way to check for a bad battery is if it is reading high and the battery is getting warm/hot to touch.

how do you know when a autu battery is charged with a Sears 10-2 amp charger? if the charger has an amperage gauge, when turned on in the 10 amp charging range, the gauge will be down to zero when the battery is charged up.

How do I use this old Sears battery charger? I do need my battery charged for an hour or two. Got this Sears charger, plugged in with the clips on the proper poles. It''s a 6 and 12 v charger. I turned it to 12 volt. No other dials or knobs on charger. Is it supposed to charge? I see nothing moving on the dial, after 30 minutes of plug in. In addition to the previous answer, make sure the charging clips are making good contact. Sometimes you have to remove the battery cables and clean the connections, as the build up an oxidation that increases the electrical resistance. Make your connections to the battery first then plug in the unit.

battery charger correct setting? hello, i have a old lawnmower that i need to charge the battery. it was running fine last spring. but before the winter i forgot to disconnect the battery. i could always charge it fine but for some reason this year i cannot remember the correct settings to charge it. it is not the average battery. it is about the size of one, but it is longer and skinnier. I think it is a motorcycle battery. First of all, here is what the battery charger says on it. it is a 1994 Sears charger First switch DEEP CYCLE or ALL OTHERS Second switch 6V 10 AMP - or - 12V 2 AMP - or - 12V 10 AMP then it has the jump start button I have tried the 12V 2 AMP but it does not seem to work. What would be the correct settings to put it on for that style of battery? It is completely dead. Or a reverse hook up? Haha please help. thanks

Can you guide me in choosing an automotive battery charger? My hubby asked for a battery charger for Christmas. I know he needs one for the lawn mower battery but also for the camper and boat. I know the battery on the camper is a deep cycle and the one on the boat is a marine battery (is that deep cycle too?) He mentioned something about keeping the battery maintained. Is there a charger out there that I can get for both types of batteries? One that will also be a maintenance charger? Or do I need to get one for the regular batteries and a second for the deep-cycle batteries? I've tried looking at Sears, Northern and JC Whitney online but I don't know what I'm looking for. I'd like to stay under $200, if possible. Thanks in advance for any advise. i own a repair shop,and you need one that will do a battery as small as a 2 amp battery which is what a lawn mower battery is,,go to advance auto parts they have a nice one for around 70 bucks,that will do all different types of battery's including the deep cycle battery's also,,i own one,and use it all the time,and have never had any problems from it,,and i think its on sale right now also,,good luck,,just tell them what you want ,and they,ll know which one you need,,good luck with it,i hope this help,s,,have a good x-mas.

Evaluating light on 9V cordless drill battery charger stays on and will not allow the battery to charge? When I place the 9V Sears craftsman cordless battery into the charger the evaluating light stays on and the battery will not take a charge. If I lift the battery out of the hole just a little bit and the evaluating light does not go on then the battery will charge. The problem is that the battery needs to be propped up very carefully and a spacer added to keep the battery from falling completely into the hole and this takes just the right tough. Many times I return to check the battery and the eval light is on and no charge. So I start again. Can the eval system be disabled? Unplug the charger. Use rubbing alcohol and clean the contacts on the battery and charger. Does it happen with both batteries? If so then you probably have a bad charger. If its just one battery then that battery is bad. There isn't any way to disable the evaluation process most chargers check the battery when you first insert it.
