How does this compare to battery tender

Same concept, but battery tender is no where close to the excellent CTEK products. I had many problems with the battery tenders I used, including "killing" my batteries. CTEK is the only product I trust. David M's answer is absolutely accurate.

I have no idea what a battery tender is. I have owned the CTEK for about 2 years now, and it does a wonderful job of de-energizing a battery and returning the battery to a full charge. It also seems to remove any memory cycle built into my deep cycle boat batteries.

It has pulse charge which gives a slight charge only when needed so it doesn't cook your battery once your battery is charged. It can also desulfinate a weakened battery and bring it back from being near failure state so you can get longer life out if your battery. Very good product. Highly recommend it.

This is a far more robust system. The battery tender is really just a plug and play. I own both and this unit gives you so many more options.

I bought it and used it twice before it quit working, have had much better luck with the Battery Tender model.

It will over charge your van battery. An additional piece is required. A voltage regulator connected inline with the charger. Battery tender might be another name

You can buy these> Battery Tender 081-0069-4 Alligator Clips with Black 2-Pin Quick Disconnect PlugAny clip with this same *wire connection* will work fine. I use the ones off of my Battery Tender because they are a few inches longer to make the stretch to a good ground.

Deltran Battery Tender® makes several chargers with more power if you are needing a faster recharge time. All Battery Tender's® are designed to fully charge a battery and then maintain the full charge. A Battery Tender Junior has an output of 750mA and will take nearly 6 times longer to recharge the same battery as a Battery Tender 5 Amp charger (part#022-0186G). If you are needing to recharge quickly or use on a larger battery then you should go with the 5 Amp unit.

As already mentioned, the 021-0128 model is the correct one for a car battery. Battery Tender's other model, the 0156, is optimized for deep cycle AGM/gel batteries that are normally not used in automotive applications. The difference between the two models is slightly different voltage points where the unit switches charging modes.

A deep cycle marine type battery typically will last the longest, but may be overkill for that application. Either way, I would use a battery tender of any type to always maintain a charge on the battery so if the power ever did go out the battery will be at peak performance until you can make other arrangements.

I am sorry to inform you that this product is designed for the 12V Battery Tender models only.Please feel free to contact me if you have any further questions.

Best to charge the battery with a battery charger, and "Maintain" the charge with the battery tender. If you have a large battery, it could take quite a while to charge it with the battery tender.

You will only need one battery tender unit if you use a splitter to both battery banks. Home Depot or Lowe's would be a good place to get what you need, and be able to talk to someone face to face.

I live in northern NJ, where the winter temps range in the teens to low 20's. The tenders have kept my batteries fines for years. A college buddy lives near Fairbanks Alaska. He keeps his cars on tenders through each winter night to prevent the battery from freezing or going down. In the morning, he disconnects, drives to work, and then attaches again at their special parking lots. They are designed for heater and battery plug-ins.

I don't know as I don't have a battery tender. If I recall, once I put the fluid in to activate it, it hardly any time at all to crank after it being on a standard battery charger.

I don't know since I have not used the other but I can see the benefits of not being battery operated. I used this on my husband's very calloused feet and feel that for a big job like that the batteries would not have had the lasting power.

I use the Ctek 7002 to maintain my 2 boat batteries over the winter. I bought it for maintenance and trickle charging as my batteries were not discharged very much when I connected them last fall. I can't speak to charging of a heavily discharged battery, but for my application the charger is slightly warm, but not what I would call hot. It sits on a fabric surface in my basement and has shown no issues.

I've been using on a 24v aircraft battery (sealed) seems to work alright, they make an aviation "tender" unit...more expensive...no long term effects yet...

I can't answer your question, sorry. I am using the battery tender on my '96 Jaguar and it is working well and doing what is advertised to do. Suggest you visit company website and post your query there. An F250 is out of my range of expertise but ask me about an Austin Healey, '50 Dodge Pickup or my '96 Jaguar and I might be more knowing. Can't spell knowledge - able. Good luck.

One of the reasons I opted for the Battery Tender Plus is that it is more powerful - so, it won't take as long as this less expensive model. This blog details the average length of time it takes for a recharge with the "plus" model: http://deltranbatterytender.blogspot.com/
