battery dead in 1.5 hrs, time to replace?

ok, so i had my truck and trailer hooked up sitting at work, i left the 4-way flashers on because i was parked close to the edge of the road on a bad corner. I came back an hour and a half later and the lights were "half flashing" a lot faster than they should be. i turned them off, then went to start up the engine, and it wouldn't even turn over, it just "clicked". so the home owner used his car to jump mine. i ran it around the block and went home, turned it off, then back on again, and it started right up. The battery gauge was where is should be once the engine was running. Is it time to replace already? or was the draw from the trailer flashers too much for the battery? the current battery is from 6/2005.

oh, and once the battery charged up a bit, the flashers worked normaly.

use led's, or leave the regular flashers off and use strobes, or get a better battery.

I would say that you just drained the battery down using the flashers on both your truck and the trailer. It happens.

Sounds to me like you need a new battery. You should be able to leave your flashers on for more then 1 1/2 hrs. we do!!

I never measure the current consumptions on the 4 way flashers, but I know I left mine on a couple of times for over 2 hrs, without any issues.

Assuming that you have a worst case 35 watt bulb, 6 of them and that they would burn constantly (not on and off), they draw around 18 amps. Most trucks have a 66 Amp / hr or better battery. This setup will give you a run time of around 3 hrs.

The correct run time is difficult to calculate, as a regular bulb draws more amps during the "cold" startup, once the wire is hot, current drops down to the rated wattage.

Buy some orange cones or warning triangles and use them instead. IMO they are alot safer and give a better warning to bypassing traffic if you use them properly. Flashers to me means your broke down and being in law enforcement I will tow your vehicle if I think its a safety hazard and your not around.
