Vmaxtanks VMAXSLR125 AGM Sealed deep Cycle 12V 125AH Battery for Use with Apllo 1500 1550 gate openers and Other Swing Slide Barrier Overhead Gates (12 Volt 125Ah Group 31 AGM Solar Battery)

I had concerns about having a Lithium battery in my truck or using it for battery backup.This battery seems to work in either situation, for more than a year now...approaching 2 years, I think.I'd feel safe buying this product again. It hasn't burned my house or truck down yet.

Great Battery and Super Awesome Seller! I WILL BE ORDERING MORE!Had a problem with the delivery address listed through Amazon, and they quickly fixed it for free! Got the battery in just 4 days! SUPER FAST SHIPPING, THE BEST CUSTOMER SERVICE.I'm using this as a second battery in my RV. My friend has the same one in his RV from 2 years ago and its still going strong.To get the most out of this battery, use the PAC BG-12 and a relay to shut down any equipment your running. It will prevent over draining the battery by cutting power at 11.6 volts and has a LED to warn you of low voltage. Secondly when storing your RV, or whatever your using the battery in, disconnect the negative side cable AND get a cheap float charger. If your not using it, don't just leave it hooked up to stuff. It will slowly drain it. Kinda like when you leave the batteries in that emergency flashlight. Then when you need it, it doesn't work. When you go to replace the batteries, they are all crusty. That's why. DON'T store stuff with batteries in them!DO NOT OVERCHARGE or DEEPLY DISCHARGE THESE BATTERIES AND THEY WILL LAST FOR YEARS.If charging with a AC 110V household type charger, make sure its a SMART DIGITAL charger.Solar charging systems usually already have this built in.Automotive alternators are also okay to use as long as its not completely dead (9 volts or less) If it is deeply discharged then use a AC smart charger to revive it.REGULAR OLD FASHIONED CAR BATTERY CHARGERS WILL KILL THESE BATTERIES.SAME GOES WITH THE OPTIMA BATTERIES. One of the reasons they have gotten a bad reputation.Any AGM (Absorbent Glass Mat) battery needs to be treated differently than the regular lead acid batteries.This one is a heavy sob 75lbs. so with FREE SHIPPING, you can't beat the price.Sorry, no more Trojans or Optimas for me, VMAX is my new goto battery.

We have been using 3 of these as the house battery bank for our 4x4 type-2 ambulance conversion. Before we installed them in our battery box, I dropped one out of the ambulance right onto its corner. It chipped off a small piece of plastic, and I wanted to make sure they were still safe to use, as I have very little experience with AGM batteries. I contacted VMax Tanks directly with some photos of my blunder, and they were extremely helpful, reassuring me that the battery was safe to use, while advising that I seal the chip to prevent long term loss of moisture and potentially decreased life. Top notch support.Our setup:The 3 battery bank is currently hooked up to a Renogy 40A charge controller on the *sealed acid battery* setting, which best matched the recommended charging rates. It's also connected to the old Xantrex FleetPower 2000 charger/inverter that came with the unit, which we left on its "flooded battery" setting, since it is much closer to the target charging rates than its "gel battery" setting, and never attempts to equalize the batteries without manual intervention (which should NEVER be done to AGM batteries). It is also capable of receiving charge from our dual alternators (through an isolator) which is regulated at a constant 14.3 volts. We can manually disconnect the batteries from the isolator, which is important in the very unlikely scenario that we seriously drain the house batteries (beyond what we ever should) and need to drive before the solar has had time to recharge the house batteries at all. With a low internal resistance, deeply discharged AGM's are subject to charging more rapidly than their ratings if placed on a charger that is only voltage regulated and capable of supplying more current than the bank's max charging current (our banks is charge-rated at 90A total, while our alternators are capable of delivering 220A).
