Actually those are both wrong answers. The box is not accurate.

In the manual it states:

320 Watts continuous.
400 for up to 5 minutes.
600 surge.

But it repeatedly states that if you go above 400 it will trip the breaker throughout the manual.

Question

Service Life

Does the battery life (not charge) decrease with time even when it is not used? E.g. if I only use the unit for the rare emergency (re-charging it every few months as needed) would it eventually stop holding a charge after a few years?

Mine is two years old and used rarely, not often recharged. I just went to charge it and it will not hold a charge. Reads FUL even though only 4.5V -- don't think I can justify buying another.

Batteries have a finite number of cycles (discharges and recharges) they can go through in their lifetime. But if you're not using the battery and charging it regularly, it will last a very long time. But eventually, even the best kept batteries will come to the end of their useful life.

I used this battery booster pack on the weekend with a 30lb thrust Minn Kota, on my canoe, in constant wind 60% of time on speed 3, for 5 1/2 hours, until it seemed almost dead, but managed another 2 hours the following day. A great deal on sale for $129, Cheaper than buying a deep cycle and seperate Charger.

You need to find out how manys amps your trolling motors draws. Divide the battery Ah by the trolling motor amps to figure how approximately how many hours of runtime you'll get (e.g. 33Ah/draw in amps=approx runtime in hours).

Question

Can this be charged via the 12v terminal posts?

I'm picking up 2 x 30 watt eliminator panels to charge this while camping, but the charge controller is older -- not the 12V car plug, but has rings to connect to battery posts.

Can i charge this battery via the 12v posts?

You CAN charge the unit using the 12V terminals but I don't think you'll get much benefit with solar panels. They'd be great to keep the battery topped up but solar really won't have enough to charge.

DC acquires charge from any source as it tries to equate the voltage between any two sources - so yes, it should be able to.

Case in point, the 12V cigarette lighter recharging method according to the manual is plugging a male-male cord from the accessory port on the device to your car cigarette lighter. This is the same port that is used to power 12V devices which means it can both deliver and receive power.

Question

How many amp hours does this battery store?

How much capacity does this battery have (in amp hours). It would help with comparison shopping.

It doesn't appear to be listed on the web page or the flyer.

Question

Will it boost/charge a totally flat car battery?

I understand some battery packs have to sense a minimum voltage before they will provide any output.

If not, is there another model/brand that will charge a totally flat battery.

Yes and no. Okay so I quick lesson in booster packs.

If a booster pack has an ON/OFF switch, it will "put out power" when in the ON position. These products have "reverse polarity warning" meaning they indicate when you've got the connection reversed BUT, if you turn the switch ON, you will still get power and can cause some fireworks.

Other units that don't have an ON/OFF switch have a built-in sensor that must sense voltage (somewhere in the 3-5V range) before it will send power to the clamps. Consider this "reverse connection protection" because you can't blow yourself up. It simply won't put out power unless it senses the minimum voltage.

So back to your question. If you've got a totally dead battery, a booster pack with a mininum voltage sensor won't do anything for you. BUT I also won't say that one with an ON/OFF switch will either. Yes, they will send power but depending on how big your engine is, how cold it is and a bunch of other factors, the booster may not have enough power to turn the engine over. Keep in mind, your car battery is completely dead so you're relying totally on the booster pack's battery which is a fraction of the size of your car battery.

So the point is, if you want a product that will at least attempt to start a dead battey then look for a model with an ON/OFF switch. If you want to improve your chances that it will actually work for you, look for one with the biggest internal battery. This Nautilus one has an ON/OFF switch and also has the largest battery of any booster pack offered at Canadian Tire at 33Ah.

By the way, the premise behind the minimum voltage approach is that even a completely discharged battery still has at least 9+ volts in it. If a battery has 0 volts, it's broke (short, dead cell, sulphation, etc.) and most booster packs out there may not have enough power to start your engine just on the power of the booster pack battery.

You can go to the source to get a charger.I would assume that your unit is suffering the same fate as mine.The gauge says full but the battery is dead.I have learned that the circuit board in the charging module is gone and not worth fixing.The 12 volt charger should still work though......hope this helps.

Try calling the number in the manual. Canadian Tire also has a universal replacement shown on this website (model 11-1599). It's 500ma so it will take longer to recharge the unit.

I seriously doubt it. Anything that heats or cools are huge power suckers.

You have to check how many watts your cooler draws, then do some math. It says it has a 33 amphour battery.

Before you completely give up on it, try and intelligent battery charger such as the #11-1522-6, which can rejuvenate some batteries and pull them back from the dead.

Always best to regularly charge your batteries, use an intelligent charger to do so, and never let them fall below 12 volts before recharging. This will greatly increase their lifetime.

It uses a 33 amp hour, deep cycle, non-spillable battery. It's usually pretty expensive to replace one of these batteries - almost the same cost as buying a entirely new booster pack.

For comparison, Canadian Tire sells a 30Ah no-spill battery (model 10-2051) for about $110. For that kind of money, you're better off waiting for the Nautilus to go on sale again!

This is not recommended. You’d be trying to charge your battery with essentially another battery. Theoretically, it could work (depending on the type of battery charger, the draw and the state of charge of the battery you are trying to charge) but it wouldn’t be fast or efficient. You’re better off getting a second (spare) wheelchair battery and a 2A battery charger to get it charged more quickly.
