How long, on average to charge fully spent AA or AAA? Will this charger charge partially chareged batteries?

when i timed it for the AA batteries it took about 3.5 to 4 hours. It will charge partially charged batteries but this one needs to be done in pairs. It's an easy to use charger, if you need something to charge quickly wouldn't recommend this. i typically use my other charger which is a rapid charger, charges my batteries in about an hour.

If you can find a USB AAA charger you like. I believe USB is 4.5V. 1.5V to 1.25V is AAA. My guess is two AAA batteries, at a time would be best since this is a low power charger.

The issue is charging current, as the charger doesn't sense capacity. If you only charged one AAA, the charge rate would be too high, .75 mA. This is why the instructions specify that at least two AAAs or 10440s be inserted when charging.

I primarily use it for a 3.7 volt lithium battery. It does charge AA and AAA batteries.

You can use AA or AAA NiMH rechargeable batteries, it holds 8, they go in positive top, negative bottom, like the pictogram on the charger... Plug it in, I leave mine plugged in all the time, have since I bought it, no problems. Just put your batteries in it, and the indicator on the screen below will show the batteries charge level and it will start charging, when it is no longer flashing, your battery is full. Nothing else required that is it.

Unhappily not directly - probably the biggest downside of this charger. However you can use the USB port to charge AAA off the solar-charged AA via a regular (non-solar) USB battery charger. I'm sure it has to be extremely inefficient and it adds extra bulk and weight if you are backpacking, but it does work. It would be a lot better if you could simply flip down the terminal to adjust to the smaller AAA (as with the regular USB chargers) or there was an adapter that let you put the AAA into the AA slots (as with GoalZero)

Yes it will charge AAAs via adapters (which are available). The PowerFilm AA charger (which does not have a USB port, but rather charges 4 AA batteries) includes adapters to charge AAAs.

Yes it will charge both sizes. It charges the AA in an outside cylinder. Then there is a shorter inside cylinder that has an upper metal strip for contact for both ends of an AAAbatteries.

Yes it will BUT when charging AAA it is required to charge 2 at a time in specific bays. The reason being, this unit charges at 700 mAh which is more charging power than most AAA batteries can handle, The total output of the device is 700 mAh so with two batteries being charged at the same time the power is being split up between the two batteries ie 350 mHa each. the owners manual sheet will tell you which position to place them in ( easy ). Option two = on the battery it should state the power output in mAh ( mili amp hour ) if the battery has a mAh rating of 700 or higher you will be fine charging one AAA at a time if desired. This mainly applies to NiCad rechargeable, NmH Nickle Metal Hydride rechargeable batteries can take a higher charging rate. If confused by above, just charge 3 or 4 batteries at a time, any size or mixture of sizes or types at the same time will guarantee your batteries will handle the charging output. Hope this helps.

The batteries are sold partially charged. Your charger completed the charge by adding 670 mAH. What you want to use is the Refresh option which charges fully,then discharges, measuring the MAH of the discharge. It will do that several times, each time the mAH is a little higher. After a number of times, the mAH no longer increases and the charger leaves the battery fully charged. At that point, you use the Display button to display the mAH. For new AA batteries, it's slightly more than 2000 mAH. Bbefore you start all this, insert the batteries, then disconnect and reconnect the DC cable, then press the Current button repeatedly until the display reads 700 mA. That makes the charging current 700 mA, which is fine for AA batteries, and the charge-discharge cycle is much faster than with the default charge current of 200 mA. New batteries need this refresh cycling to reach their rated capacity of 2000 mAH. If you just use the discharge-test mode, you will get less than the rated 2000 mAH. Look on the Internet and you'll find all of the above and more.

Not directly, it only holds AA batteries. However if you a AAA charger with a USB plug I'd imagine it would charge them. It may lose some efficiency though if it has to convert wattage/voltage. Hope this helps!

It does come with a charger that lets you charge AA and AAA sized batteries. There's not a way to charge C or D batteries included.

The unit will charge any combination of one to eight AA and/or AAA NiMH batteries, regardless of mAH rating. Mix and match - the charger doesn't know and doesn't care.

yes it will this is a great charger for the price . I got it because i needed to charge aaa and aa :)

I have never tried to do that as I have a seperate charger for all my other batteries. Since this charger came with the batteries thats what I only use them for. You could try but I really dont know if it will have any bad effect on your AA batteries.

It can charge 4 AAA/AA/C/D batteries at a time in any combination. It can also charge 2 9 volt batteries at a time I've used it with AAA/AA & C s with no problems.

Sorry, I misunderstood your first post. Are you using this battery pack to charge rechargeable batteries, such as AAs or AAAs?
