what is the best 18v ah size battery and how many hours are they good for before recharging?

I am not sure if it's the best 18V battery or not but, I have a Bosch BA-612 18Volt (2.0Ah 36.0Wh). I have not used my radio strictly off of battery power to see how long it will last however, I know it will last 1.5 -2.5 hrs. in my cordless impact driver.

I use the 4 ah battery for campin trips and usually get about 16 hrs at a moderate volume. My little 1.3 ah batteries make it about 4 hours

The unit uses 2 six volt 4.5 amp hour recharagable batteries like this one:ExpertPower EXP645 6V 4.5 Amp Rechargeable BatteryThe batteries should last just about forever if you don't let them discharge fully. I think that you can get up to 6 hours use maximum, The longest I ever used mine was 4 hours. Just keep the batteries charges as per the instructions

I prefer this AAA battery set, they last months before having to be replaced. The newer built-in rechargeable battery set i believe they advertise as having a 24hr battery life before having to be recharged. That made my selling point the AAA pair.

You can get ones that last ~20 minutes. Search 2200 mWh parrot ar drone battery and you will find one.

The rechargeable batteries last about 8 hours of continuous play. They are great for travel. Regular AA batteries might last 3-4 hrs of continuous play.

I'v used rechargeable batterys in mine for over 2 years NiMH Rechargeable Cell: AA Size, 1.2V 2600mAh from www.batteryspace.com/

For anything using AA batteries, I recommend Sanyo Enerloop rechargeable batteries. They are many times better than any I have used previously. They not only have good duration, but also hold their charge unused for a longer time.

same battery with a bit more amp hours, should work quite well for you. I don't run out of power any more with these in my pocket.

I recommend the Orbtronic 3,400mAH 18650 rechargeables and the Intellicharger i4 version 2. The Orbs are quality Japanese parts batteries and all 6 of mine charge to exactly the same 4.7 voltage every time and they seem to last forever. The Orbs are also have been rated top marks and fit this flashlight well. Keeppower is the only other one that is about as good IMHO.

This is a 12V battery, but for running even a small winch that still pulls ~40 amps I'd go for a bigger battery. This one is rated for 18 amp-hour (hinting it'll supply 18 amps for 1 hour, or 9 amps for 2 hours, etc) and I don't think it's a good idea to pull more than that 18 amp rating for more than a few seconds (like to crank a car).

I have 6 12 V 35AH batteries. I wish I had one more panel to charge in one 5 hr period. Here are my calculations. Assuming a 50% charge, each battery needs about 17 AH to recharge. 2 panels each put out about 8 amps. so 8 hrs X 16 amps is 128 AH. 128 / 17 is about 7. So my answer would be 7 35AH batteries.

I use one of these, Philmore Battery Holder for (6) AA with Standard Snap Connector : BH363 instead of a 9volt battery. I'm getting 5 to 7 hours for the camera depending on how recent the rechargeble batteries were charged. The battery pack has more amps which will lead to a longer run time than the single 9volt battery.

The Batteries work pretty much as advertized. However I have never had electric tools with 18v before so I can't give you a direct comparison.

I can't check out all the models, but I checked my own several DC18RA chargers (in different locations) bought with tools over a number of preceding (~3-4) years. They all work well and seem fast. I usually buy an additional battery and have never run out before the backup is charged. Of course, I'm not a professional user.

Hello Kristin, We can't speak for other sellers of this product, but if you purchase from Battery Supersite, we ship the higher capacity version of this battery which IS sealed (non-spillable) lead acid and 100% rechargeable. It has the same 12v output as the 12v 4.0ah, but is rated at a higher capacity. The capacity is listed as the "ah" rating, or amp hour rating. The amp hour rating is simply just the capacity of the battery and how much reserve power it can store. It's like the gas tank in a car; the larger the gas tank, the longer it can run. We always search the market for high quality batteries that will have a higher capacity but keep the output the same. The important thing to check is the voltage as the voltage should always be the same (ie. a 12v cannot be used where a 6 volt was used). A good example of this is the 4ah and 4.5ah battery. Nearly every battery manufacturer has updated this size battery to the 5 amp hour battery which will provide up to 20% longer runtime than the previous capacity battery. Feel free to contact us with any questions. Battery Supersite "The Amazon Battery Experts"

This is a bolt-on type connection battery. An 18Ah battery may be used if you have the additional space for the larger size.Amp Hours for batteries equates to Capacity for fuel tanks. The higher the amp hours, the more "fuel"; the longer the battery may operate before requiring recharging. I have personally added batteries to increase a 35Ah system to 70Ah which considerably increased the range of an electric vehicle.

Not sure how you plan on using them, but you need to know your wattage needs. these battery's are rated 3.7V 5000mAh (5 amps for 1 hour) So 2.5 Amp for 2 hours, 1.25 Amps for 4 Hours, etc...
