Battery Tenders

[mainiak1]

I have a battery tender on my tractor it works great. I don't use my tractor much in the winter.

As for the picture of the burned out wires on the camper. This guy was probably trying to use his twelve volt system while the battery tender was still plugged in. They are not supposed to be used like this.

Hi...


I have the Battery tender by Deltran...
used it for ~7 years now... mostly on the motorcycle year round...

...in winter... switch it to the camper battery... garden tractor battery... and CUT battery (outside)... and motorcycle...

..no issues with it...

The quick disconnects available for it... and the regular terminal clamps... make it EZ to switch from one battery to the next...

My brother gave me one like this for Christmas. Seems pretty good.

Anyone run one of these on a diesel truck?
It appears that some of them will charge up to four bateries in parralel, which would allow it to work on a truck with two batteries.

Also the manufacturer discussions appear to imply that these units do not discharge the battery and then recharge them to maintain the charge. The just charge them up and hold them.
The advertised difference between the "tender" and charger appears to be that the tender charges it up and then reduces the voltage to prevent damaging the battery when connected up for a long period of time.
This feature may also be possible with some of the better chargers, but I have not looked into it for sure.
The charger I have appears to atomatically stops applying voltage when it senses the battery is charged.

I have been using the BatteryMinder for the past year and am very pleased with it. BatteryMinder

I have run down my ATV batteries by leaving the ignitions on and once they get a deep discharge they are ruined. At $55 per battery they are much more expensive than a battery tender so I think the tender is a worthwhile purchase. I tried using a large charger set at 2 amps for a tender but ruined one battery doing that. From what I have read, leaving a big charger on a motorcycle/ATV battery, even at 2 amps, will gradually overcharge it. Thanks for the link to the BatteryMinder.

Some of the Tenders are pretty cheap, like 14 bucks at harbor freight. they turn on and off as the battery needs it comes on and as it is charged it goes off. only provides a little power though, like less than 2 amps. the best thing is some of them are pulse generators which pulses the battery and knocks off the sulphate off the battery plates which is the primary cause of old batterys dieing. the build up sulphate on the batterys lead plates. that leads to the demize of it ...

not sure if the 14 buck ones do that but I know some of them advertize the pulse info as a Plus... a lot fo the NEW battery chargers will turn OFF automatically but will not turn back ON automatically! so watch out for that too.

I wonder how these work for the breakaway battery on a trailer.I am thinking they might be good especially for winter months when the trailer isn't used much.

Anyone tried them for that?

I got a Battery Tender Plus over the winter to keep my new battery in tip-top shape. Now that's it's getting warmer (I actually tilled today!) I'm wondering if it's worth keeping using it in the summer? Does this extend the life of the battery, or in any other way help during summers when the tractor will typically be used on at least a weekly basis for mowing and so on?

Thanks,
Bob
