yes.. Ampere-Hour ginagamit sa pag-measure ng charge ng battery.. 1 Ampere-Hour is 3600 Coulombs or 36000 Ampere-Seconds..

since engr. tayo, dapat scientific ang way ng pag-solve.. Given: let x = output voltage = 12Vdc y = capacity = 10Ah z = output current = 1A Required: t = ? (time it takes for the supply to be drained) Solution: ahhh.. ewan ko.. the formula to be used is.. uhm..
basta i-assume na lang na constant yung 1A na load current.. ahihi  Answer: 10Ah/1A = 10hrs (more or less 10hours)  |

for Nickel Family and Lithium based batteries, 10 hours actual. for Lead Acid, dependent sa type, pero ideally 10 hours din. exponential na ang discharging pagdating sa mas mataas na current. like sa 12V 10AH, ang 2.5A ay hindi na 4 hours, 3 hours na lang, ang 10A ay hindi na 1 hour, 30 minutes na lang.  |
