If your duty cycle is 50%, that means you split your radio time equally between talking and listening. Duty cycle and why it matters.ĭuty cycle is expressed as a percentage and is the term used to describe the ratio of transmit to receive. In fact, the radio will draw continuous peak power only when transmitting in the AM mode, which is seldom used anyway. A modulated signal will cause the current to swing up and down, hitting the peaks only momentarily. Under most conditions an amateur will be transmitting only part of the time, and even then, the radio will not continuously pull maximum amperage. As we’ll find out soon, these estimates are way overstated.īut first let’s deconstruct this. In the receive only mode, assuming an average of 1 amp, the battery will go for 35 hours. Following the math, the 35 amp-hour battery should push James’ 22 amp transmitter for a little over ninety minutes. The 0.5C-rate (or c/2) would be 17.5 amps for two hours, and so on. So what can he realistically expect from this setup?Ī 35 amp hour battery can provide 35 amps for one hour. He plans on adding a solar panel at a later time. James wants to run his radio with a 35 amp hour AGM battery and charge it with a 2 amp plug in charger. The official Yaesu specifications state that this radio consumes maximum 22 amps/304 watts on transmit, and 0.55-1.5 amps/8-21 watts on receive depending on the audio level (these numbers are rounded). Off Grid Ham reader James (whose question was the inspiration for this article) asked about going off grid with his Yaesu FT-450 radio. Before you can know how much battery you “need”, first find out how much power all your stuff consumes and what you plan on doing with it in the real world. It certainly does not help that many of the answers floating around the internet are based on guessing, hypothetical conditions, and overly generous manufacturer data. Before asking the question, provide some answers. The question is too open ended and comes with too many variables to give a definitive answer, but there are some basic battery concepts that will help you sort through this confusing topic. In layman's terms, if within the first year of your purchase your Beats Solo3's are seeing significant problems with the battery, and you haven't damaged the headphones in any way, Apple will probably replace the battery for you.It’s always some variation of “How big of a battery do I need to run my (fill in the blank) radio?” It comes up a lot, not just in my email but also on the various forums and blogs I visit. If your product was damaged accidentally or needs other repairs, you might need to pay an additional fee for service." If your product fails because of a manufacturing defect in the battery and it's still covered by the Apple One Year Limited Warranty or consumer law, we'll either repair your product or replace it. "Batteries are consumable parts that sometimes fail because of a defect or because they wear out through normal use. If you are experience battery problems, Apple's battery service for its Beats headphones may be able to help you out. Lithium-ion batteries don't function properly when they are too cold or too hot, so avoiding leaving the Beats Solo3 somewhere where it will be exposed to extreme temperatures. One more thing that can severely impact battery life is temperature. Your settings, environment, and usage will all affect how many hours of listening time you will see. If your phone and the Beats Solo3 are struggling to stay paired over Bluetooth, you'll likely burn through the battery power a little faster. The same can be said for being too far away from your device. #How much battery life do i have full#If you're blasting the headphones at full volume every second you use, you'll likely see a dip in battery performance. In our testing, the quoted 40-battery life of the Beats Solo 3 is accurate, but it's important to mention that your mileage may vary depending on how you use your Beats Solo3 headphones. The real "magic" behind the battery life with the Beats Solo3 is Apple's proprietary W1 chip. #How much battery life do i have Bluetooth#Of course, the Beats Solo3 can use a regular Bluetooth connection, but that would likely see a decrease in battery performance. ![]() Basically, the W1 chip that works with iOS 10 and later, does a bunch of heavy-lifting and makes the Bluetooth connection more stable and efficient. The real "magic" behind the battery life with the Beats Solo3 is Apple's proprietary W1 chip, which they describe as Class 1 Bluetooth. When you're talking about 40 hours of wireless listening, it's not a bad question to ask.
