What is Ah in batteries?
Amp hour
What is the difference between 12V automotive and 12V marine batteries?
without knowing exactly the types of batteries you are talking about but generally marine batteries are a higher quality battery and have higher amp hour ratings which basically means they can turn the stater for longer
Can you use a 600 amp hour battery instead of a 400 amp hour battery in a portable phone?
The "amp-hour" number is the length of time the battery is expected to lastbetween charges, in normal use. It's a way of describing the battery's capacity.The device in which it's installed won't know the difference. The real differenceis that you won't have to recharge the battery as often.Make sure that the voltage of both batteries is the same. If they're not, thenyou can't do it. If they are, then go right ahead.And by the way, batteries with 400 Amp-hour or 600 Amp-hour capacities arecar batteries or truck batteries. They're bigger than a breadbox and weigh aton. The batteries for portable phones may be 400 or 600 mAh ... milliamp-hours.1 Amp-hour is 1,000 milliamp-hours.
What happens when a 70 amp hour battery is connected to a 50 amp hour charging circuit voltage of both batteries are being same?
The 50 amp charging circuit will never be able achieve a full charge for the 70 amp hour battery, thus in effect turning the 70 amp hour battery into a 50 amp hour battery.
What will happen to battery capacity if two batteries are joined?
Connecting two 12 volt batteries together in series would doubled the amp hours ie 125amp hour +125amp hour = 250amp hour and the voltage stays the same at 12 volts. Connect them in parallel and the voltage will double to 24 volts and the amp hours will stay the same ie 125 amp hours.
Do two 12 volt 100 amp hour batteries give me 200 amp hours at 24 volt?
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours
Car batteries are normally rated inn ampere-hourWhat does it mean?
Understanding AMP-HOUR Ratings of BatteriesFor example, if a battery has a 10 Amp-hour rating that means that the battery should provide a current 10 Amps for ONE [hour], or 1 Amp for 10 hours, or 5 Amps for 2 hours, or 2 1/2 Amps for 4 hours. By using the Amp-hour rating, you can determine the "size" of battery needed by multiplying the current [Amps] you need to do a job, and how long [in hours] you need that current to be supplied before having to recharge the battery.One caution however, Amp-hour ratings are not always 100% accurate, and you must be prepared to recharge more often if the battery does not actually produce that much power.This problem usually manifests itself when the power is drawn out of the battery in huge amounts/rates rapidly. When a battery is discharged at a very slow rate in relation to its capacity, then the Amp-hour ratings are usually very accurate.
Does attaching batteries in parallel increase their amp hours?
Yes, it does. I you have N batteries in parallel each batter supplies 1/Nth of the total current to the system. So basically each battery (and therefore the entire system) will supply power to the load N timers longer. Amp hours = Amp*hours, so if you multiply hours by N you multiply your Amp hour rating by N. Hope this helps. p.s. Amp hours do NOT add in series... basically because 1 Amp*hour = 3600 coulombs and it represents how much charge flows from the batter.
How many watt hours in AA battery?
This question doesn't have a simple answer. It depends on the battery chemistry and construction. Somewhere in the battery's specification is the amp-hour rating. For AA size batteries, it is common to use milliampere-hour ratings (mAH). You need to multiply the mAH rating by 1.5 if you're figuring alkaline batteries, or 1.2 if you're figuring rechargeable batteries. Then divide the result by 1000 to get watt hours. Nicad cells are typically rated 500 to 1000 mAH. NiMh batteries typically have twice the rating of similarly sized nicad batteries. Alkaline batteries are typically rated at 2500-3000 mAH
Will 10 10000 amp batteries power a 1000 watt light?
To do a proper calculation please state what the voltage of the batteries equals. I have never come across 10000 amp batteries.
What is cost per amp hour speaking in terms of batteries?
Varies with the battery. I just bought a deep cycle battery last week at Walmart. 115 amp hour (trolling motor battery) for about $74.00. That is a lead acid battery. Other types and sizes will vary.
What way is used to connect batteries together to provide more current?
Connect them in parallel. They must be the same voltage and the same or similar amp-hour rating.
