Thanks JohnJohan said:no .it will just keep your equipment running for less time...the Ah rating tells you how many amp's you can pull if you want things running for 1 hour. if you pull 7 amp's and want it to last for 3 hours, you'll need a 21Ah batttery. if you only pull 1A, a 7 Ah battery will last 7 hours
