Product Description

Batt Tend 4bank

Amazon.com

The Battery Tender 12-volt/1.25-amp 4-Bank Battery Management System is designed to fully charge up to four 12-volt batteries simultaneously and maintain each at its proper storage voltage without the damaging effects caused by some trickle chargers. Compatible with all AGM (absorbed glass mat), sealed maintenance free and flooded batteries commonly found in some automotive/farm equipment, motorcycles, ATV’s, and personal watercraft, this lightweight, microprocessor controlled unit provides safe, constant, four-step charging current for every vehicle stored in your garage, shop, barn or boathouse.

Safe, Smart, 4-step Battery Charging
The Battery Tender 12-volt/1.25-amp 4-Bank Battery Management System is much more than a trickle charger. Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows users to simply connect the charger to up to four batteries, either in or out of a vehicle and forget about it until you are ready to use it, with the confidence that the batteries in all four vehicles are being maintained at optimal performance levels. This makes it perfect for seasonal and recreational vehicles like motorcycles, jet skis, ATV's, snowmobiles and more,. It is also safe for your battery because it utilizes advanced microprocessor technology that automatically switches its output voltage to a storage or float level. This feature eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of a charging battery. If or when the battery voltage drops too far under load, this same smart technology resumes output power and the charging cycle begins again. The unit also features spark-proof connectors, short circuit and reverse polarity protection, an easy to understand charging status LED indicator for each charging bank, durable yet lightweight construction and almost no current draw from batteries connected to it.

Key Features:

  • Four independent charging stations.
  • 12 volts/1.25 amps per charging bank.
  • Extremely lightweight at less than 3 lbs.
  • Operates anywhere in the world. 100-240 VAC, 50/60 Hz.
  • Microprocessor controlled constant current charging.
  • Spark-proof and reverse polarity/short circuit protected.
  • Temperature compensated to ensure optimum charge voltage according to ambient temperature.
  • Perfect for all AGM (absorbed glass mat), sealed maintenance free and flooded batteries.
  • Designed to meet U.S. and International product safety standards (UL/CE).
  • 2-year warranty.

*Note: All Deltran battery chargers will charge all types of lead acid batteries: either flooded (standard STD), sealed maintenance free Absorbed Glass Mat (AGM), or sealed maintenance free gelled electrolyte (GEL) batteries. However, for optimum battery performance in deep cycle applications (for example, running a trolling motor), it is best to chose the Deltran charger that has the charging software specifically designed for the battery type. Fortunately, since the technical staff at Deltran has developed charging software that works equally well for both STD & AGM batteries, the only choice to be made is between 2 models: either STD & AGM or GEL software.

Style Name: 12-Volt 4-BankConfiguration: Management System Verified Purchase
I purchased the Battery Tender 4 bank charger-maintainer in June of 2009 through Amazon. Its primarily use was to maintain batteries in my motorhome. After 9 months of continuous use one bank quit working. The unit was listed as having a 2 year warranty, but when I called Deltran Corporation I was advised there was a $25 evaluation fee, even though it was still within the warranty period. There was nothing in the instruction booklet that prepared me for this. It showed the length of warranty for each of their maintainers, but no mention of evaluation fees. I was politely told that this information was posted on their website. Their website indeed showed the "evaluation fees" for each of their products. Basically all repairs are free for the first 90 days, after that you have to pay the evaluation fee. This applies to all the Battery Tender chargers-maintainers. Since the repair, there has been no further problems. It has been in use now for 17 months. Would I have purchase it had I know about the goofy warranty? NO. I am not bummed out about the failure of the unit, "things happen", but I am with regards to the warranty. My advice would be to visit their website and completely understand the warranty before you purchase any of their maintainers.

The only regret I have is that I didn't buy one of these sooner. It works perfectly! Keeps my boat batteries at 100% and worry free. It is a step up from the one bank model as it is fully electronic and lighter in weight with a high quality plastic case. The original steel case.

I have used this charger to maintain batteries in my riding mower, two motorcycles, and two batteries in my F-250 diesel. The two separate charging banks work well. It has indicator lights for each bank that work independently and properly - no 'sharing' of lights leaving you guessing as to the status of each battery.

Also, I was on the verge of replacing the two batteries in the F-250 because they had sat in the cold and heat, only getting driven infrequently, over the past two years. They had gotten to where they would barely hold a charge. After hooking them to this Battery Tender, I believe that these batteries have been (at least mostly) 'repaired'. Attaching this charger and slowly charging and de-sulfating these batteries has gotten them to the point where they 'appear' to be as effective and hold a charge as well as ever. I can drive the vehicle and not worry about bringing along a charger and/or cables, 'just in case'.

The same is true for all my other batteries - the engines all start as though they have a new battery in them by using this two bank Battery Tender. I feel like this unit has more than paid for itself versus the cost of replacement batteries.

Recommendation - if you have more than two batteries to maintain, buy extra battery leads so that you can easily alternate this unit to all of the batteries. I have had great success alternating this unit between four batteries (three-four days between switching).

Updated 11/08/2009 - since I have been so satisified with this unit, and I now have more travel coming up, I said the heck with it and bought another one - Amazon's price made this a no-brainer. Now I don't need to alternate the charger between batteries - they are all covered!

I've been riding for well over 20 yrs and the Deltran Battery Tender is one of the greatest products you can buy for your cycle!!

In the early years, I was playing with trickle chargers and/or starting the bike once or twice a month over the winter months, only to always seem to be pushing the bike down the alley come spring, trying to pop the clutch to get her started because the battery didn't make it through the winter with a decent charge....again!

About 10 years ago I bought a Battery Tender Plus at a cycle shop's open house. They were rather expensive then, but thought it worth a try considering the sale price. Loved it!!! Still have that original one, although I have been through a couple of the Jrs.

With 5 streetbikes in the garage, it seemed like a no brainer to invest in this 4 bank version. Did a little shopping around and found this to be the best deal. I had read somewhere, (although can't recall where), that this model had leads 12 ft long, so I didn't see the need for the extentions. Wrong!!! Leads are only 4.5 ft long each, so I wish I would've got the extentions. 25ft is a bit long and I have seen 12ft elsewhere.

Again, fantastic product for the off season or if you're fortunate enough to have a multiple bike stable!!

This little baby will keep your batteries charged up! My two are maintaining the charge on batteries in an ag tractor, a Caterpillar skid steer, ATV, and lawn mower. Now I need one for a two-battery diesel truck that is rarely driven any longer! Should have bought these long ago.

This is a great product that I don't know how I got along without. We have a couple of riding lawn mowers, ATV, and off road vehicles. Every spring we had to deal with replacing batteries, and during the summer after a few weeks of idle time we would have weak or depleted batteries. We have setup all of the equipment with quick connects. Everything stays charged and ready for use. In the dead of winter when we needed to pull equipment out it started without incident. This spring the savings in replacd batteries paid for the unit. Great product.
