How long would it take to charge a 12V battery system?

Charging time will depend on several factors... how sunny it is, how much capacity (rated in Amp Hours) your battery has, etc. The R15-300 produces 0.3A (at 15V) to charge a 12V battery. For example... If your battery capacity is 10AHr (amp-hours) and it's down to 70% full, that means you need to add 3 AHr back in... As this panel produces 0.3A, that means in 10 hours of full sunlight (max sun) you will restore the depleted 3Ahr. Of course, the sun intensity isn't always at max strength, so it would actually take longer than that. If you need to recharge faster, then a larger panel will be needed. I hope this helps explain it.

never used it. did not have the watts to charge my solar generator. i can't answer your question any ways. you did not say the watts of the power film, or the amp hours of your battery and type. sorry. good luck.

Depending on the battery condition the charger may take more than 7 hours. The last amount is at low current to fully charge.

NOTE: 1 watt at 12vdc means this only produces 1/12 amp. This is a "micro" trickle charger. Look at plug in trickle chargers on Amazon-- they range from 1/2 amp to 1.5 amps. So it will maintain a battery lead acid if it is small and is not operating too many systems such as car clocks, on-board computers, etc. 1/12 amp for 12 hours is only 1-amp-hr. So if your battery has a 100 amp hour capacity, it will take several hundred hours to charge it accounting for parasitic losses and changing battery voltage.

If you're asking how long it takes to charge this battery, approximately 6-8 hours if you use a 2.1 amp charger

You would have to put 4 batteries in series and all would have to be in about the same condition--not an optimal method. you would be better off putting two 6 volt batteries in series on a 12V charger

The charger puts out 3.5 amps. Given the size of your battery, simply divide the battery ampere hours by 3.5. For example, an 80 ampere hour battery will take almost 24 hours to be fully charged. A bigger battery, i.e. 160 ampere hours would take almost 48 hours. The time will depend on the state of charge when you put it on the charger.

Any 12 volt AGM charger should charge your battery bank. The calculation that you need to consider is how fast you want the battery bank to charge and size your charger appropriately. Yes, this charger has a battery type mode to accommodate AGM battery types. Looking around on the internet, this battery charger on its highest setting of 70A should charge your bank of batteries in 14-18 hours.

I have those same batteries and it takes between 2 and 4 hours to charge them depending on the level they are when you put them in.

For this Belkin grip 2000 mAh battery case, you can charge it at 2 amps and it will take 1 hour. It will take a half hour at 4 amps.

That depends on the battery. When I charge my lipo 2s 5000 mAH battery, its under an hour. Also, there is a quick charge feature if i;m not mistaken. There are reviews of this charger on youtube so you might want to check that out as well.

Generally speaking it takes no more than an hour to charge a completely depleted battery. With that in mind, it's good to have more than one battery for your camera.

I assume you plan to use your car battery with 120v converter or an XPower 300 watt convert. They will give you over 3 hours. Good luck. Reg

From 0 -100% on the trickle charge it would take about 35 hours. On the 12 amp setting probably 16 hours.

That is a great question. The short answer is yes, if you have the right solar panel. The device is furnished with a 12 volt 2 amp switching power supply. According to the product description on Amazon, "[the] Included 100-240V AC adapter recharges the battery in just 4-5 hours." In order to match that charging time, your solar panel would need to provide 12 volts at 2 amps. I wouldn't recommend that you go much above 12 volts, but you should be OK with a nominal 13.6 auto battery charging source. I don't know if there is a boost regulator in the Anker box or not, so I don't know the minimum voltage that will actually charge the device. But if you can get close to 12 volts, your charging time should be proportional to the current your solar charger can supply. My US$ 0.02. John

With the stock battery around 12 minute's. .i bought a high performance battery as an extra and it runs almost 25 minutes. . Charging varies with battery size.. around an hour i think. You want to let a Lipo battery cool down before you charge it.

Yes, you can. But you need to be aware of problems that may arise from overcharging your car battery. This is designed more for short term charging where you won't leave the panel/kit connected for more than 24 hours. Ideally one should not charge a battery for more than 12 hours. It is safe for a 10 amp charge for that time frame on vehicle batteries. Smaller batteries like atv or motorcycle batteries should get 2 amp for 1-2 hours. Make sure your water levels are up before charging. Also, if you are storing a battery for extended periods of time, charge it every 3 months. Once the charge is less than 12.6 on a 12 volt battery, they start to degrade. This reduces the life of the battery as well as the true cranking power. The safest bet for long-term charging is to use a charge controller which will monitor the voltage of the battery and maintain the proper levels. Something like this would work great: http://www.amazon.com/Brunton-Controller-12-Volt-Battery-Monitor/dp/B000P696QS

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.
