For example, if you have something that draws 20 amps, and you use it for 20 minutes, then the amp-hours used would be 20 (amps) x .333 (hours), or 6.67 AH. The 20 Hour Rate is the accepted AH rating time period for batteries used in solar electric and backup power systems (and also for nearly all Deep Cycle batteries).
âYes, sir, a stop payment on a check is only valid for six months.â I asked if there was any way I could cancel the check permanently. âYes sir, you can renew your stop payment six months from now. For an additional $30.â At this point, I was getting agitated.
Checks are stale after 6 months. The bank may or may not accept the check if it is over 6 months if it is a government check. These are almost always good (money is available to pay the check).Other checks are questionable as to the funds availability. If the chech has a expiration date, you'll have to get the issuer to reissued the check to you.tate of Michigan, check is dated 5-4-2009. Has it expired already?? How long do you have to cash/deposit a State Income Tax Check before it expires?? Thanks!!!
