what is the weight difference between the 4 hr & 8 hr battyeries?
355249
Someone already gave you the exact weight with battery installed as 4.8# and 5.8#. I traveled from NC to Alaska, think all together I was on 9-10 airplanes(including a small 8 passenger) and one large ferry, and could not have asked for a better set up than Inogen. Just have to keep on top of the re-charging so there is always enough backup, just in case of a problem. If you do travel, I take along the 25' tube for hotel rooms, much easier to exist this way.

The battery is about 1 1/2 time heavier and larger (still much better than carrying bottles. If you have the Inogen One G-3 shoulder case the case can be easily expanded to hold the larger battery. The 8 hour battery is nice if you are unable to carry a spare battery with you and you will be out for longer than the 4 hour life of the smaller battery. We travel often and this makes the trips much easier especially when it comes to flying. The inogene One G-3 is allowed for air travel in the U.S. This arraingment works great for me.

Whether it is 7 or 7.2 amp hours is not really an issue, they are interchangeable and you won't notice any difference in actual operation. I don't know what the actual weight is since I didn't weigh it and is already installed in my ups. I would estimate that it weighs at least two pounds, maybe a little more.

24 Watt Hours is equal to 1.33 Amp Hours. To put that in perspective 18 volt batteries rated at 4 Amp Hours have 72 Watt Hours of available power (multiply Amps times Volts to get Watts). Watt Hours is a better way to state available power because with Watt Hours you can compare 12v tools to 18v tools.

The 5.3 lbs would be more accurate than 8. This laptop is not that heavy at all and definitely not 8lbs!

The weight is 43 oz. without the battery installed. The BAT619G HC 3.0Ah battery weights 20.6 ounces, so with this battery it weighs 4 lbs. When I bought mine, there were 3 different batteries available, so the weight with a battery of course depends on which one you use. There is a variable high and a variable low speed setting, variable between 0 and 500RPM(low setting), and variable between 0 and 1700RPM(high setting).

The product description (and box) say up to 8 hours but my box only says 4.

I don't know if 12v 7.2ah is the same as 12v 7ah. Probably, but I don't know. The battery weighs a couple of pounds. It is not light, but has density and thus feels like 2 to 3 pounds.

I have both, and I use them on a chainsaw and a cultivator. The 2AH can go up to 20 minutes of hard continuous use on either machine, and, obviously, the 4AH can double that time. But it's almost double the weight, too, so if you're going to do a lot of overhead limbing with the chainsaw, the lighter battery is the better choice. I am glad I have both.

AA are 1.5V and ~2600 mAh. 9V typically have ~500 mAh. This means 2 AA have ~7.8 joules of energy and a 9V has ~4.5. So 2AA should last longer if the power consumption is the same. Of course the quality of battery varies but for starters at least.

The G-Max 4 AH run time is roughly double the time of the smaller G-Max 2 AH. Even running with two 4 AH in the lawn mower my wife finds that if the grass is longer than usual she will run out of power with two 4 AH, so it would make life simpler to stick with the 4 AH battery.

I like the 750 except that it's not battery like the old ones, I don't think the 800 has battery option either. If the 800 has batt. option go for the 800.

I could not find source for weights, 9098 battery is smaller and lighter,charges faster but has a smaller storage capacity. If you work overhead a lighter battery helps in my experience.

It is the same Voltage and Ampere Hours as the Hot Wheels Battery. The only difference that I can see maybe is the colour and size. But you had better check if the connector is the same. Sorry I cannot help you on that. Phone Fisher Price. !!!!

The description on the back of my battery rates it as 7.4V 2200mAh. Li-On isn't mentioned -- assume it stands for lithium ion, which these are. Work great in my Core micr+wire gloves, now going on four years! Got new batteries a few months ago. Caveat: I can't get more than 2 hours out of batts without recharging, and usually a little less. I keep a second pair charged for longer periods. And, recharging fully usually takes about 4+ hours. Still the best thing I've found for my colder-than-normal hands during Colorado foothill and mountain days below about 30F. The gloves are even better fitting, more flexible, and sleeker than most outdoor activity gloves. The description on the back of my battery rates it as 7.4V 2200mAh.
