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.
RE: ff: Most checks are stale dated after 6 months, unless specified by the check. IE: Not valid after 90 days or something similar. However, say for instance you wrote a check in December of last year and the person you wrote it to just cashed it yesterday. When you get your monthly statement for July, you can dispute anything on your account for up to 60 days past the date you received your statement.
