What is this - Output 1: 3.0V, 1000mAh - Output 2: 4.2V, 1000mAh? How can Output 1 be 3.0V? The battery being charged is rated at 3.7V to 4.2V.

Theres a switch to swap charge modes. The terminals move up and down to accomodate many different battery sizes. The 3V mode is for lower voltage batteries. The 4.2V mode is for the included batteries.

I don't know the actual output, but we have two of these and no one has had any problem charging anything with them. They are used daily for such things as phones, e-cig batteries and a Kindle reader. Hope this helps.

It's the same unit. Voltage of a battery will vary somewhat based on its state of charge, so a statement of the voltage of a battery is a "nominal" value, not precise. This unit probably charges to a maximum of 40v, with a typical voltage of 36v and somewhat less as the charge is depleted.

the output voltage should be 4.2V and output current 300 mA. if you look carefully at the picture you can read this, but it is wrong in the product description. the 12V refers to the car charger input voltage. why 4.2V for a 3.7V battery? it is common for chargers to be at a higher voltage than the battery it is charging. there are sensors that detect what voltage the battery is at and once the battery is close to charged the charger lowers the current applied to ensure that the battery is charged thoroughly and quickly.

3.7v vs. 3.8v is fairly insignificant. The real worry is if the voltage output of the new battery is higher than what the OEM battery is. The real question is the tru maH of the battery coupled with the claimed voltage output. As you use a battery, the output voltage will begin to drop a bit, especially under a heavy load. A 3.7v, 3250 maH battery is probably just as good as a 3.8v, 3100 maH battery.

Output power supply is 7.5 volts D.C @200 mANot sure what any of that means, but read it off the charger unit.

I have the 4000 mAh version which is not pictured on the page I'm looking at right now. But according to the back of it, it's Output is 5V ~ 0.5A.

It says..10.8v 5200 mAh ..& I have no idea what that means :) ...an update....mine only lasted about 6 months :(

Hi Kat, Yes these batteries are 1.2v (the standard voltage), and are rated at a capacity of 2ah 'typical', and 1.9ah "minimum" . I am quoting these specs directly from the label on the batteries themselves. Hope this helps. greentyco.

The output voltage is the V4.3, the output current is the 70ma. Hope this helps.

I received the 1800 mah battery shown on the right of this link: http://ecx.images-amazon.com/images/I/51mY5a2Jn2L._SS400_.jpg . This was taken from the ad several weeks ago which has since been updated after I voiced concern to the seller. However, no resolution was received. I don't recommend this product and have left a review accordingly.EDIT: After escalating, Amazon agreed to refund my purchase. Not sure if it was done through the site or seller.

1 amp = 1000 ma (milliamperes) batteries are rated for 10 hours using this method so. 3.4 amps per hour for 10 hours.

The battery we received is a 40v Lithium G-max, 146 Wh battery. I'm not sure how this crosses over to the amp hour rating. If they assume you have a constant 40v for the whole charge, that would be 3.65amp hours. If they take into consideration the voltage degradation over time or that it would not be used at a constant 40v output, they may estimate it at 4 amp hours. The battery model is #29472.

3.4 x4.9 cm is the NV size. i don't know what the difference is.says it's 1000mAh 3.7v 3.7whhope that helps.

I measured 28.3 V right after charging them. One battery after sitting unused for weeks was reading exactly 28V. The battery is rated at 28V and 76 Wh lithium Ion. My old batteries are rated at 28 V and 3.0 Ah. My old batteries date back to August, 2006 and still have power but don't really last too long. I definitely needed new batteries and these are strong...but expensive.

In case anyone was still wondering about this, I just received mine and the sticker on the bottom says that Output is 5V/900mA, so it's not a full 1A, but pretty close.
