    Battery Tender Is The Best

    I have been using a Battery Tender many tears for my Harley-Davidson to keep the battery fully charged year around. I bought this Battery Tender Jr. for my John Deere tractor to keep the battery fully charged on a year around basis. Batteries last so much longer when they do not have a major swing in there charge. Great thing to have if you want to make sure you always have a full charge. Great for even storing your vehicle over the winter and not have to worry about a frozen battery or loosing all your electrical settings.

    I own three of the Battery Tender line of products. This one, to keep a back-up battery for my whole house generator ready for duty & two other units (a waterproof 800 & a Power Tender). The other two keep my RV chassis & coach batteries fresh when the RV is not in use. All the Battery tender units work great & keep the batteries in "like new" condition.

    I found it very easy to install and I like the option of using the aligator clams or hard mount. The one part I wish was better is the cap for the 2-way connector. I have hard mounted it to my ATV so with the cap not staying on the connector will be exposed to the elements you encounter on an ATV. On a side note, I was shocked to discover the price on line compared to the price in my local store. I was pricing this item out at the store and took a cell phone picture of the price so I could compare it to other places. The price on the shelf was $34.97. As I was seaching the item on line the same item was priced at $23.00. I clicked on it and low and behold it was the Wal-mart sight. It said the retail price was $25.00 on sale for $23.00. So I orderted it on line and had it shipped to the same store I say the shelf price of $34.97. With in 2hrs it said my item was ready to be picked up, so I know the item was pulled off the shelf at the store for me and not shipped there. This does not sit to well with me because now before I purchase anything above $20.00 I am going to check the price on line and compare it to the in store price. I am also wondering how many other items I have over paid for over the years.

    This does exactly what it is supposed to do, keep auto and deepcycle batteries fully charged without overcharging. If you have a dead battery, it will take forever (if at all) to charge it up. Its float charge is 13.05-13.08V, pretty consistent across the four chargers I own. I am able to keep two 115Ah batteries fully charged on one Tender Jr., but have to fully charge them with a standard charger then disconnect and immediately attach Jr. So, I have eight deepcycle batteries that the four Jr chargers are able to keep topped off. With a couple of 12V-110V 1500 watt power invertors I am able to run my furnace, refrigerator, tv and a few lights when the power goes out. I'm in Minnesota, today its -10, so power outages can cause some pretty severe problems fast.

    • A. I had an old Jeep that was parked outside all the time and run infrequently. I was jumping the battery every time and tried the battery tender jr. on it. It took a couple of days but charged the battery up and refreshed it. Still would drain after a few days without running it but kept me going for another year.

    • A. No, the BT Jr is NOT a charger, it maintains peak levels. Batteries have a small drain due to things like clocks, stereos etc. if the car/motorcycle sit for a long period of time the BT jr keeps the battery fully charged. Whether in the vehicle or out of the vehicle. Works great. My car sits for several months due to the cold weather so I keep it plugged in for several months at a time.

    • A. Not sure what you mean. If you have a bad battery you must get a new one. This will not fix it. Google, what does the lights mean on a battery tender jr. I believe it will indicate a bad battery by the way the green and red indicator lights do, flash etc.

    • A. Doubtful. Try it to see if you can get any charge into the battery with the tender Jr. It might put enough of a charge (if the battery is totally dead) into it to get your full size charger to charge it. This may take a couple of days on the Jr.

    Or, do you have to charge the battery for a long time to get the car started? Also, is it better (more efficient) to charge with the cables or cigarette adapter? Will the battery 'plus' charge faster? ... Is this a good, safe battery charger for women? Thank you.

    • A. Will not jump start. Designed to maintain a battery (at idle) but will eventually charge a battery not quite fully charged. This device charges at a rate of 3/4 amp as compared to a typical battery charger charging at 10 or more amps. Will automatically "float" or basically stop charging when battery is fully charged and resume when battery needs a small charge. This is an excellent device for anyone with limited mechanical experience in that once installed, all that is required is to connect/disconnect the connector and plug/unplug Tender into a wall plug or extension cord.

    • A. According to the directions, if your battery is below the level to start the car, it may take a long time to charge the battery up to full or even crank level. As in "days". If your battery is fully discharged, you'll need to take it to a shop and have them put a full charge on it. Then this maintainer will keep it charged up. This is not a jump starter and it is not a regular battery charger. It will maintain an already charged battery that is in good shape. The "Plus" maintainer puts out a higher amperage so it will charge back up (maintain) a battery somewhat quicker. But remember, this is not a regular full featured battery charger. This is a battery "maintainer" for cars that must sit for long periods of time causing the battery to drop below crank level. And yes, my wife loves it too so it's safe for women to use.

    • A. The Battery Tender Junior is a 750 MA (3/4 amp) charger. It will NOT jump start your car. Hooked directly to the battery or through the cig ligther, should not make any difference in the charging rate. If your lighter does not work without the ignition being turned on, then the battery won't take a charge through the lighter. (Ignition would have to be on) The Battery Tender Plus has a little higher output, so it should charge a little faster.

    • A. No, you cannot jump start a car with this charger and if the battery is low the Junior will take several hours to bring it back to full charge. If the battery is very low you may have to use a higher rated amperage charger to bring the battery up to charge before you can start the vehicle. I use the Juniors to maintain the charge in batteries when I am not using the vehicles regularly. I mostly use them with my motorcycles but also keep one on my Ford E250 van, my 1981 VW Rabbit convertible and my Granddaughters 2013 Ford Mustang GT to keep the batteries charged during the winter months. The chargers can be left connected all the time because when the battery reaches full charge they go into float mode and cannot overcharge the battery. Great chargers and a lot cheaper than having to buy new batteries in the spring.
