Amazon.com Product Description

BatteryTender Plus is the most advanced charger/maintainer on the market specially designed for today's sealed lead acid batteries. The BT Plus uses micro-processor technology in a four stage charging profile to charge, improve, and float your battery so it is ready when your are. Constant current charging and regulated voltage patterns allow the battery to be recharged fully and safely without the fear of overcharging.
The Battery Tender Plus 12-volt/1.25-amp Battery Charger is the convenient solution to the challenge of keeping 12-volt vehicle batteries optimally powered when not in use. It is able to charge any lead-acid battery--including standard and sealed AGM and Gel Cell battery types and is also designed to be easy to use in difficult spaces, to utilize a 4-step charging program and safely function in a fully automatic mode. Taken together this makes the Battery Tender Plus 12-volt/1.25-amp Battery Charger an excellent means of ensuring that your battery is fully charged and ready to go when you are.

Safe, 4-step Battery Charging
The Battery Tender Plus 12-volt/1.25-amp Battery Charger is much more than a trickle charger. Powered by BTP microprocessor technology, it has a "brain". Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows you to simply connect the charger to a battery, either in or out of a vehicle, and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, at the end of the regular charger cycle the it automatically switches its output voltage to a safe, storage or float level that eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of the battery. If or when the battery voltage drops too far under load, output power resumes and the charging cycle begins again. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an easy to understand charging status LED indicator, a quick connect harness for use in hard to reach areas and almost no current draw from batteries connected to.

Key Features:

  • Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell).
  • Complete 4-step charging program (initialization, bulk charge, absorption mode and float mode).
  • Automatically switches to float / maintenance voltage after fully charging the battery.
  • If the battery voltage drops too far under load, full charger output power resumes.
  • Temperature compensated to ensure optimum charge voltage according to ambient temperature.
  • Solid state two color LED indicates stage of charger.
  • Spark proof and reverse polarity protected.
  • Includes quick connect harness for use in hard to reach areas.
  • 10 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.

"Battery Tender" 2010-01-31
By John P. Cortese
Old one finally died after 20 years so I had to get a new one. Have put these on my motorcycles and sports cars over the winter for a long time and find them indispensible. I expect this one will last a long time too. I highly recommend it if you need to store a vehicle over a long period or winter.

With the winter coming we purchased this for both of our cars so that in case we have battery problems we have this trickler to boost our batteries. I have not had to use it yet.

"Battery Tender Plus" 2010-01-30
By M. Rein
Very easy installation. Works as advertised; plug and play. The charge cord that attaches to the battery could be a little longer so that it could be easily routed thru the grill, rather than raising the hood to connect the charger. There may be a longer accessory cord, but it hasn't been enough of a hassle for me to look.

This Battery Tender works great! I will use it on my RV in the winter and my hot rod the rest of the year.
