You should not need to upgrade your battery. The amp is 150 watts, which is pretty minimal change to power draw on battery.
Sorry, there was a problem. Please try again later.You shouldn't need to upgrade your battery with that small of an amp. It should only draw about 15 amps. Unless your battery is old. Hopefully it has the purchase date on it. Or you have the receipt if you purchased it. AutoZone will test a battery for free , maybe your alternator too, and should be able to tell you if it's getting weak or not. Make sure your alternator drive belt is in good shape and tight enough. Clean the battery cable ends and battery posts. Some cheap battery manufacturers recommend replacing after about 18 months. Better batteries can last anywhere from 3 to 5 years. Sometimes 6. The projected life of the battery may be on the label of the battery. You might see something referring to a span of time where you can get free replacement. Or a part number with "yr" at the end of it. Usually the number just before the yr is the projected number of years the battery will last, or how long it's guaranteed for. Depending on how often and how much you deplete the battery, and for how long you use it in this depleted state, can affect the longevity of a battery. Same if you live in a colder or warmer part of the country. My advice is that if you're going to upgrade your battery, do a little research. Do you have a liquid acid core battery? Or is it a newer dry cell? If it's liquid acid, find a battery with the highest aH (amp hour) rating and most amount of reserve minutes, that will still fit in your battery tray/holder, and that you can afford. If you're car does take an acid battery, you can put as big of a battery in as you want. All acid core car or truck batteries are "12 volt" batteries. All standard car and truck alternators charge at a rate of about 13 to 14.5 ac volts. Charging amperage may differ a little. But not much. Your not going to hurt your alternator or your starter by putting a bigger battery in. 12 volt system is a 12 volt system. 12 volt battery is a 12 volt battery. Hope I helped. If you have a dry cell battery and an electronicly controlled alternator, I'm old school and don't know much about these systems, yet, you'll have to ask someone else. I imagine the principals are the same. I do know that newer Civics will appear like the alternator isn't charging at idle. Until you turn on all of the accessories. Headlights. Radio. Rear window defogger. Blower motor. AC. ECT. The alternator only charges if there's a need for it on newer vehicles.
