How important is AH rating? I have a 12v 7.5 AH rating. Will a 7.2 work or is a 9AH better?

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.

9 Ah will give a longer run time. If the original is 7.5 Ah, the 7.2 Ah battery will give similar but slightly reduced runtime.

The mAh does not matter, but I am unsure what the 2.6 means. As long as it is 3.7V, it should work.

Not to sure what will the performance be at 9~12V. You might want to contact the sales support at AmpFlow through Amazon. Else look at the Power curve chart when you browse the said motor. Sorry I'm not able to give you any more help.

The original battery that came with the driver is 1.2 or 1.3 Ah battery. The major companies that sell 12v products are always trying to increase the Ah. Bosch now has a 2.0Ah battery. This gives you a little more run time.Some batteries have the Ah stamped on the battery itself, some you have to read the package label. The bottom line is a 12v is a 12v is a 12v. They will all work. Use what came with the driver and then you can upgrade as you need to 2.0. I have never seen a 12volt batter with a 4.0Ah rating. Don't get fooled.

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...

500 mA is .5A This unit is rated for 1A, or 1000mA, so should be fine.Also, I had no problem in receiving the item, although as I recall, it took a bit of time.

you need to give the AH rating of your 12v battery to determine charge time.

First, thanks to Kevin for telling us that the adapter is a 12volt adapter (from the label). I just want to add that my battery pack - as I suspected - outputs 9 volts; the six AA batteries are indeed in series. Therefore, I suspect anything from 9-12 volts should work. Also worth noting is that when my batteries died the other day, I just rotated them and am getting some more use out of them; I expect to have a power source fabricated by the time I need to replace the batteries.

I would use the small 12 setting. I have a 105 ah and I leave it charging because it will only charge when the battery needs additional charging. I maintain my battery year round on this setting.. This is not a quick charge charger but rather a charger that maintains..

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

Read the discription. U need 12 v pannels renology sells them. If u are changing the voltage to ac. Its really not advisable to do it at 12 volts. 24 or 48 is way better.

You shouldn't need a different charger. Just be sure you wire the batteries exactly the way the old ones were. The ah rating just means the batteries you are purchasing will last longer under load before they discharge.

Odd, my 12v model only had 2 wires, Brown and Yellow, and being 12 I didnt think it mattered which was which, but generaly, I chose the brighter of the two(yellow) as the +, and installed an in line fuse, works fine, bright as hell. Id rate it at nearly 1000 lumen when connected to my Deep Cycle 12v Boat battery.

The unit I received says 14.4 volts, 18.7 watt hour and 1300 mAh. That is 1.3 AH. So neither is accurate. How about that. Plus, if you divide 18.7 AH by 14.4 volts the actual AH is 1.2986...actually less than 1.3AH. Not all is as it seems!

most often these items are rated only in "amps" can you tell us the amp rating on your motor?DanCSH

Well, that load is within spec. I have not run mine this hard, but at this price it seems worth a try. I have had excellent performance thus far at 48V, probably 2-3 A.

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).
