Q&A: Lithium Ion Batteries

It has been a little over two months since the launch of the Series 2 products, and one of the featured improvements are the use of Lithium Ion batteries. Since then, several questions have come up regarding the difference in batteries, safety concerns, storage, etc., so we’ve put together a Q&A list of the most commonly asked questions. 

-      Are Lithium Ion batteries dangerous?

  • The Lithium Iron Phosphate (LFP) batteries used in our sound systems are not dangerous. We’ve installed two failsafe systems into our programming which stop the battery from ever getting too hot or swollen. 
  • Most battery issues occurred with the cell phone industry, which include a different kind of Lithium Ion: Lithium Cobalt and Lithium Manganese. These two batteries are used in cell phones and other small consumer electronics.  They have a very high energy density; perfect for when you need as much power as possible in a very limited space. The downside of having high energy density is that they can be unsafe if not properly designed and/or manufactured.

 

-      Will I notice the difference between Lithium Ion batteries and Sealed Lead Acid (SLA)?

  • The main differences you will experience is longer cyclelife, lighter weight and longer shelf life. Lithium Ion batteries are less than half the weight of SLA –  2.2 lbs vs 6 lbs – and have the capacity for 2,000 charge cycles vs SLA which has 250. You are also now able to store your system for 8-10 months without affecting the battery life, whereas the SLA could only be stored for 3-4 months.  

 

-      Do I need to keep my system plugged in during storage?

  • Optional! You may store your system for 8-10 months unplugged - without affecting the battery. 

 

-      Do I need to fully charge my unit before storing it?

  • Not necessary. 

 

-      Do I need to run the battery to empty before storing it?

  • Not necessary, however, we recommend storing at 20-30% battery level. 

 

-      What is the warranty on the Lithium Ion batteries?

  • The batteries include a 4-year warranty with an option to purchase a 2-year extended warranty. You can find out more about our optional Extended Battery Warranty here

 

-      Do I have to send my unit back to Anchor Audio to get the batteries replaced?

  • If the battery is under warranty, units will need to come back to Anchor for battery replacement, so we can verify if it truly is defective. If your unit is out of warranty and you would like to replace the battery yourself, you may purchase the battery through Anchor Audio, and we will ship it to you. Since our batteries cannot be shipped via Express due to the categorization by shipping providers, an additional fee for special handling will be added to the battery cost and shipping fee. 

 

-      How do I know if my batteries are defective?

  • A battery is considered defective when it holds less than 60% of its original capacity. This equates to 4.5-amp hours or less for the Bigfoot, Beacon, Liberty, and Go Getter and 2.7-amp hours or less for the MegaVox and Acclaim.

 

-      What is the standard lifespan of the battery?

  • If the unit is used daily, you can expect the system to last about 5.5 years at 100% charging capacity. The batteries will still be usable after 2,000 charging cycles, however, it will only recharge to about 80% capacity. 
  • Once a battery exceeds the estimated 2,000 charging cycles, it does not mean it is unstable. Up to that point, the battery will recharge to 100%. Once it exceeds 2,000 charging cycles, it will only be able to hold a charge up to 80%. 

-      What does it mean when you say it lasts 2,000 charging cycles?

  • One charging cycle is from full charge to empty. Therefore, your battery will last approximately 2,000 charging cycles or 2,000 complete recharges.

 

-      Where can I get replacement batteries?

  • Replacement batteries have to be purchased from Anchor Audio as they are designed to optimize our battery status indicator. Please contact our Technical Support team before using third party battery replacements as this may void the warranty. 

 

-      Can I use SLA’s in my new Series 2 unit?

  • You may use SLA’s in the new unitbut the Active Fuel Gauge will not function properly. 

 

-      What type of Lithium Ion battery is used?

  • Lithium Iron Phosphate (LFP)

 

-      Why do you call it a Lithium Ion battery and not a Lithium Iron Phosphate?

  • Lithium Ion is a blanket term for several types of lithium-based batteries.
