What's the difference between 12v 18ah vs.12v 18ah/20hr? Thx.

if you are asking about 20ah vs 18ah the 20ah has more plate material inside and one gets longer amount of operational time with same 12volt power. Rule of thumb is the 20ah will cost a little more vs 18ah batteries. While doing the same job lasting a wee bit more time before needing recharge. Both will do the job just different times to recharge. ah is amount of work the battery will provide. bigger number means more work TIME will be provided, as long as both are some voltage. In this case 12vdc.

I think you two didn't understand the question, I think he's asking what is the /20hr mean, it means that if you ran just under 1 amp you could run it for 20 hrs, while the other ones dont tell you the hr rate of the ah rating...

The only thing i can tell you is the bigger the number ah the longer the distance or the longer the run on one charge for instance i use them for electric bikes 12 volt 12 ah gets me 6 miles a charge 12 volt 18 ah gets me 10 miles a charge 12 volt 22 ah gets me 12 miles per charge so on and so on

Doesn't matter. 12V 4AH means the battery is 12 volts and has a capacity of 4 amp hours. The 12V 5AH has the same output as the 12V 4AH, but a 20% longer run time as stated in the description. As long as the voltage is the same, amp hours can vary. I ordered a CA1240, received a CA1250 - no problem. They are the same size. My last battery was a smaller 12V 1.2AH and worked fine for 7 years.

yes 20 volt are the same I think. You can't use 18 volt as connections reversed on batteries to prevent it.

The batteries are quite light. Weight is not an issue with either battery. They are both 20 volts. The 4AH vs. the 2AH battery is like having a bigger gas tank, not a bigger engine.

9AH is better because it should last about 20% longer when the power goes out. 7.2AH will work, it just won't last as long.

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.

I can't guarantee it, but I see no reason why it wouldn't work. I bought one for my alarm system with the old battery failed, and it works fine. Both are 12V and 4ah. The 20hr probably refers to how long the battery would last with the system in alarm mode.

Ben, if you have a batteries plus close by, take it there and they will install it for free and you will get a 20 ah battery vs the 18 ah one that comes from the factory!

The smaller 12 volt is better used as a hack saw the larger 18 volt is better for cutting lumber not enough power with 12 volt to use on 2x4 s and other wood continuosly

I don't know, I only have the 24 Volt battery. I guess you would have to get the dimensions of both and compare them. Also, will an 18v battery power a 24 v. unit?

went with the AH 20 dementions were the same as the one I took out which i believe was a 12AH not sure. anyway just make sure the dementions are the same and were the cables hook up.

The main difference between the two inverters is the supply voltage for the inverter. The 12 volt inverter will need a 12VDC supply such as found in most passenger cars and light trucks. The 24 volt inverter will require a supply voltage of 24VDC and is typically used with farm equipment, heavy machinery and many military vehicles. Both inverters will produce 120VAC at the output.

No, you need the one that says 12V 12AH UB12120 not the one that says 12V 7AH that is the difference, and you can get it cheaper on Amazon verses Batteries Plus

Hi Sherrie C. Yes the 12v battery can be used on the 18v vacuum with less run time. (Be aware some 18v tools wont take the 12v battery without a small modification).

If you were to restate 3000mah (milli-amp-hours) to just 'ah' you would see it stated as '3.0ah'... So the 3000mah battery provides more power than the 2600mah battery. Essentailly, the 3.0ah battery will provide it's power for a longer period of time than the 2.6ah battery. So your Drill Driver, etc., will keep it's strenghth a little longer 3.0 vs the 2.6... Hope that explains it.

I don't know what the 1.5 Ah is, but I checked on my 20 Volt Dewalt that I purchased and on the Battery pack, it shows the following: {20 V (Max) 1.5 Ah 30 Wh Type 1}. I guess it is the same thing. I just wanted to let you know that I love the power and the quick charging of the batteries. I keep both of them with me in my truck.

Fat chance, no off course. The 20V is a slider while the 18V has one cell sticking out so you need to push it into the tool cavity. Two different form factors by design so you have to buy new tools and batteries. Sucks, they could make it interchangeable, not just DeWalt but all other brands. Not much difference between 18V and 20V in that the tool should work with either voltage, just battery not interchangeable by design.
