Question

i have a cordless phone that uses 700 mah but are hard to get hold of so was going to get the 800 mah. but i don't know if there would be a problem.

Answer 1

NO.

Answer 2

Paul R is correct. The 800 Mah battery would be a better battery because you would get more usage out of it... compared to only a 700 mAh battery. Also you can buy the battery you are looking for at www.needbattery.com They have every kind of battery, low, low prices and a great return policy. I buy ll of my batteries from them.

Answer 3

Yes, assuming they are the same size/voltage.  mAH stands for milli amp hours in other words how many milli amps the fully charged battery will supply before it goes dead.

So if you had something that draws 70 ma, and used a 700 mah battery, it should last 10 hours.  Thus the higher the mAH value the longer the battery will last, a 1400 mah battery in the same device would last 20 hours.

Generally instead of bringing down the price of the nimh batteries they have simply continued to increase the mAH output and kept the price the same.  So usually if you see nimh batteries at a low price it is because they have low mAH ratings.
