can i use a 5.0 AH when the current battery is a 4.0 ah?

By no means am I an expert at batteries or electrical, but I went to a local battery store and spent $30 for a 5ah battery. I has been several months since installing it and no problems.

4.0 AH (Ampere Hour) rating indicates the capacity of the battery. It means it can provide max current of 4 A for 1 hour. A 5.0 AH can replace the 4.0 AH without problem.

I tried to do the best match of the battery that I purchase. I would ask my local battery store as well. I am pleased with the battery that I purchased.

Douglas, It should be compatible. Make sure it has the same type terminals. You could also consider upgrading to a 5.0 AH battery like I did. One that should work for you is CA1240 12V 4AH FIRST ALERT ADT ALARM BATTERY NEW PS-1250. Available from Amazon and highly rated. the 5.0 AH batteries are slightly larger, but there was plenty of room in my panel to accommodate it. 5.0 AH means it will keep your system running 25% longer once the power goes out. Hope this helps. Max Richardson

the 5ah replaced the 4ah and 4.5ah, which are not made anymore(read from another battery site)...you will get extra run time from the 5ah and it is same size and same 12volts

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.

I think the volts (V) is the number that needs to match but the mAh does not. In fact, if the mAh number is higher than the original battery, you should notice improved performance.

I have several 4.8 adapters I should have disposed of but didn't. I need a 5v adapter and I believe 4.8 would suffice, but the tips are ever so slightly different in size, of course, so none would connect. +/- 2 v shouldn't make a noticeable difference as far as I know since battery voltages vary as they drain with no ill effect on the equipment..

Yes you can use the higher mAh batteries as long as they are 1.2V and the batteries are the same size. The higher mAh will just have allow for the lights to stay on.

You can use that battery as long as the physical size is the same and voltage is same as 4228, and new battery has to have same or more voltage and amps but no less.

Ken J was real close. You have to take 80% of the atv battery's AH rating (which, by the way, can be anywhere from 4 AH to 36 AH). You never discharge a lead acid battery 100% (12.0 volts open circuit is discharged, 12.72 and up open circuit is fully charged). They have a very high resistance to recharge when you discharge them completely. So a 5 AH battery has 4 AH available. Drawing 3 amps for one hour is 3 AH. So that battery would only last about an hour and 20 minutes give or take a few. A 36 AH could go over 9 hours. So it ultimately depends on what AH battery you use.

Your 7.2Ah refers to amp hour rating. On my home alarm system I went from 4Ah or amp hour to 7Ah. Per my alarm installer, the higher the amp hour rating the better the battery is. As long as the 12 volt is the same you should be fine. Always buy the minimum required battery amp hour rating per the system you are installing it on but you should be fine with a higher rating.

Yes you can. I found the higher mAh,the longer the light lasts. I use the 4500 mAh. This light is used daily these higher bats last me a week between charges.

You shouldnt need measurments. Match the model or serial number to your old battery be sure voltage is the same

"1.5 Ah" has to do with the battery size in amp-hrs. The 20 volt DeWalt uses the 1.5, the 3.0 and 4.0 amp hour (Ah) batteries.

I'm pretty sure you can't make a 9.2 out of 7.2 . The only thing you would be doing is changing the power from the 828 fh to the m-510

I use the 4.0 AH battery all the way back to X2 tools.. this is wen the 1/2 in driver drill impact driver could give a big red a run for its money .. today's rigid tools are emerson crap emerson dont pay out to keep up in the battery game like other mfgrs do so they on back end of battery tech.. gotta pay to play.. 69 bux for a 4.0 ah battery with three yr warranty aint to bad they at store now just bought two..

Yes. Just make sure that the battery compartment is large enough. If there is a failure of your household electrical supply, the 7.5 a/h battery will provide backup power to your alarm system for a longer period of time than the 4 a/h battery. It takes less than five minutes to replace a defective battery - make sure that you dispose of the defective battery in accordance with local hazardous waste disposal requirements.

The battery comes upgraded to 5AH. I guess it's a marketing strategy, but it works.
