Battery Keeps Dying, Voltage not as high as it should be?

just get a battery load tester from ebay for like $20, and that may tell you what the auto store you went to didnt... that your batt may be dead.

waste of money

that batt charger is good

pull batt from car and charge overnight

Yes its my main and only battery, but i don't usually play my system with the truck off

i was saying thats what the yellow tops are good for (playing your system for a longer period of time with the vehicle off). they drain much slower than say a red top and as a result, take much longer to charge. a red top is good for a DD because it charges up real quick and is more reliable IMO.

if you think a battery load tester is a waste of money you are silly... i pulled one dead batt from an array of 5 total in my crx and GAINED a healthy amt, not to mention my voltage came up alot after it was pulled... its a cheap and useful tool.

red tops arent meant to be drained and charged agian. THey will die alot quicker than a yellow top. If ur gonna get a optima get either blue or yellow(both are deep cycle batts)

sure it is a waste if you can use a DMM to check voltage.

disco all batts and wait a day or so and check with a DMM

they should all be within 1 or 2 tenths of each other.
