Product Description

Free Standard Shipping!

Order today and receive free standard shipping on your Battery Tender 6/12 Volt 4 Amp Battery Charger - 10 Banks. Only valid in the contiguous 48 states and not valid with any other offer. Physical address required (No PO Boxes).

Safe, No Spark Charging! Deltran's advanced SuperSmart Battery Tender Battery Management System is light years ahead of any standard battery charger. It's the first fully automatic, constant-current 6/12 volt battery charger designed to charge and/ or maintain up to 10 6/12-volt batteries simultaneously @ 4 amps.

This Multiple Charging Station Shop Charger uses 10 independent Battery Tender Plus battery charger circuits in a single enclosure. Each circuit is a linear power converter that has a true DC output at a maximum power level of approximately 29 watts. It has a maximum output charging current of 4.0 amps. This is a higher current output than the stand-alone Battery Tender Plus battery charger circuits because each shop charger has an internal fan to provide forced air cooling of all active, semiconductor components.

Tech Tip: Using A Multi-Bank Charger

Each bank of this charger is 4 amps. Combined, this is an output of 40 amps (10 banks of 4 amps each). This is commonly used in two ways:

  • Connect each bank to separate battery systems, charging both by 4 amps each.
  • Connect all banks to the same battery system, charging it by 40 amps total.

Arrived broken...

This is a good battery charger, but the one I received had two dead channels and a dead power light. Called Battery Mart and they said to contact the manufacturer for a warranty claim. I was disappointed in this response as it is brand new and I think Battery Mart should deal with it as it wasn’t right in the box, but that’s where we are. Waiting to hear from Deltran on my unit. I will edit this review (if possible) when the issue is resolved.

Works pretty well

This works well with one exception- it has a moderately loud cooling fan that runs continuously. I've got 8 batteries on it currently and even though all are in a float mode, the fan still runs all the time. As long as it continues to work like my single tenders do, I can live with the fan noise. It's just odd that the single tenders don't even have vent holes in some of them and the multi-battery tender has a continuous fan. Best pricing and quick shipping. It's worth it.

I have to maintain a fleet of motorcycle batteries that are factory activated so they need to be maintained constantly until they're put in a vehicle. This makes it easy for me to do them in bulk and alternate inventory to keep everything topped off.

Works Great - Marine, Motorcycle & Lawn

was delivered on time - Battery Mart had the best price - the same unit sells for up to $1,000.00 at alot of differant suppliers. I really like the fact that I could plug in my Lawn tractor, Marine & Motorcycle batteries all at once and just leave them -- no more throwing out batteries in the spring time - will pay for itself after this year
