## Questions & Answers

**Q: Why should I get this battery instead of a considerably less expensive Universal Power Group (UPG) battery with the same ah rating?**
A: VMAX batteries will be better for several reasons. Even though the amp hours are the same, all VMAX USA batteries feature high performance military grade plates. Also, the metal plates used in VMAX batteries are thicker. This results in a higher quality, longer lasting, and heavier battery (For example the VMAX857-35 weighs 25 pounds, the UB12350-D5722 weighs 22.6 pounds, both are 35Ah). The VMAX also includes a standard carrying handle, and features a tough and durable outer casing made of extra strong ABS plastic.

**Q: I want to purchase this battery for my storage room,that doesn't have outlets,Which inverter power supply to use ? Thanks**
A: doesn't anybody realize this is an electrical item and in order to answer these questions we first need to know the amperage or watts that your device uses and then AND ONLY THEN you can answer all these questions. Take the amperage draw of your device and multiply it by the hours you will use the device per day and this will give you the amp-hour rating of the battery you will need to run your device for a day. Make sure you multiply the answer by two since you don't want to discharge the battery more than 50% to extend its life. I can't believe that the people who own these electric trolling motors do not know the amp draw and refer to them by pounds thrust. This does not answer the question of what size battery you need for a specific run time per day, hour or various days.

**Q: how well will this work for my watchdog backup sump pump system**
A: not familiar with the sump pump system.  If it is 12 v dc.  I have run almost continuously a 55 lb trolling motor on it for over 4 hours and it still had power.

**Q: I just bought this battery and it isn't holding a charge...only lasts for a little over an hour...charge it up and the same thing happens....??**
A: Try getting a small solar panel especially made for charging small batteries.  It will work while your out on the water fishing but remember a solar panel still gives the battery a slow trickle charge

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great.
*by A***T on March 29, 2024*

When I got this battery and went to pic it up, the weight was awesome. My first thought was:how big is the thing?When I opened it up and looked at it my first reaction was, this is a joke!Wasn’t too much bigger than a motorcycle battery.I was afraid to use it because it looked like it would run down pretty fast. So, I went and bought another bigger battery just in case this little thing ran down and catch me in the middle of our small lake.Well, I hooked up the smaller battery and after two hours I loaded up and came home.To my surprise, it was still in the green on the power.This is one great battery. Don’t let the size fool you. This little thing is almost heavier than my bigger battery. It has the power to push a boat.If you want a battery that will last on power,This is the one. It should have “ever ready”written in it. It just keeps going.

### ⭐⭐⭐⭐⭐ Compact trolling motor AGM  deep cycle battery
*by E***S on July 24, 2012*

I got the 35 amp hours rated battery (35 amps for an hour) and rated for 18-40 lb thrust trolling motors. Mine is 30 lb thrust.The 'AGM' type, deep cycle, sealed battery was well packed (box in box) and has 2 terminals with hex head bolts that are screw in bolt with washer type posts clearly marked with a reddish color plate for the positive contact. It was 100% charged when I received it. Sturdy white plastic 4-attach-point handle.The real nice surprise is its size and weight. I had a WalMart battery (like a regular car battery dimensions) for several years that finally failed, but performed well. But the VMAX857 is considerably smaller in all dimensions and a lot lighter. One hand handling versus a heavy 2 hand weight for the WalMart battery.For a canoe or kayak outfitted with a trolling motor (mine is the Native Watercraft Ultimate 12), weight and size are paramount. So the VMAX is a much better choice than a 'dual purpose battery' and can be run down to about 1/2 capacity with no harm. By using a 'PWM' digital controller ($25 on eBay), the current draw is reduced a lot and more usable power to the motor.For a casual trolling motor duty, used at lower speeds (like 1-3 of 5), this battery should recharge over 100 times if normal. I used it for the first time today, always at low or 1/2 speed for about 1 - 1.5 hrs running time. When I got home, I put it on the charger and it was still 100% charged!January 1 2013 update: Now that I used it most of the spring and all summer into October as a trolling motor battery, I can tell you that it works great for my small 30$ trolling motor. Having an electric motor rigged with digital PWM speed and pushrod type steering control for your canoe/kayak opens up a lot of fun! Paddling is slow, you cannot fish as you paddle, and if a storm comes up.... with a motor you have a way to get to shelter more quickly than paddling (and I paddle as well as run the motor!). If you insist on a canoe, get a square backed one for a troller or outboard (typically 2-5 hp). And look at the Native Watercraft Ultimate series!

### ⭐⭐⭐⭐⭐ 8 years as my start battery for my Yamaha 25 electric start on my Gheenoe
*by A***N on September 17, 2024*

Getting ready to go out for another holiday . . . It started my 25 Yamaha without issues. The boat sits under a carport in Central Florida "heat". Good Job Vmax! Will buy another whey this one get 'tired'!
