[QUOTE="12VoltInstaller, post: 3354446, member: 564140"] I have personal experience with the red and yellow tops. The yellow tops I have....one in my daily driver. has worked great the whole time....dont do the key off much but havent had my batt die and not come back to life....good battery. I have had 3 yellow tops in my show truck and they have all been crappy....a cell goes bad after being in there for any time period with the key off. I have had to have 3 of them pro-rated to get a new one. I shifted over to a red top and havent had a single problem. If your not going to use them to deep cycle....go with the red top. Better ESL/ESR rating....(charge, discharge) I have been under the impression that the yellow top is a car audio battery....but that (I assume) is for the deep cycling properties. I like my amps not to starve when they are playing...and I dont have a bank of batteries so I run my car when I listen for any period of time with it loud. If you want good batteries....Look Into Kineteik power cells....they are a good combo of battery and cap together.....much less parasitic than a cap....greater power discharge than a battery with the same CCA rating. Batcap is another solution you could look into. There is really no substitution to an excellent 200 to 300 amp alternator....that will solve 95 % of your charging/power supply problems. Short of running 3kw ++ of amp power...you need batteries regardless of what you do when you need huge current....bats can supply bursts of large current....alt can do what it can do....its all give and take. imho [/QUOTE]
