The main benefit of having a rechargeable speaker is the ability to take it anywhere without having to worry about plugging it in to an AC wall outlet. And while some rechargeable speakers come with a large enough battery for what you will be using it for, some people will find that their speaker does not have enough juice to last the length of their entire event. This problem usually arises during tailgate parties or other outdoor gatherings.

To solve this problem, many speakers come with an external battery input jack which allows you to purchase an extra battery and connect it to the speaker to lengthen the battery life. To utilize an external battery you will need the following:

Ext. Battery Input Jack

Speaker with Ext. Battery Input

Make sure you have a speaker with a 12V External Battery Input Jack. You can see a collection of our speakers which have an external battery input jack here.

Next you will need a battery connector cable. The correct cable will be red and black and one end will have two clamps and the other end will have two exposed wires. Some rechargeable speakers will come with this cable in the box but if your speaker doesn't come with it you will need to purchase one separately.

12V Battery

A 12V battery of any capacity. When looking for a battery, make sure it is rated at 12V and search for the capacity which will be well suited for your use. For example, if your speaker has a 7Ah (7000 mAh) battery and you want to double the battery life, you should purchase a 12V 7Ah battery to achieve this. Here is a collection of external batteries that we carry on our store. 

 

Now that you have all the materials, follow the below instructions to safely use the battery and extend the usage life for as long as possible. 

1. Insert the exposed end of the red wire on the battery connector cable into the red clamp of the external battery input jack, and the black wire into the black clamp. Connect the red clamp on the other end of the wire to the positive terminal of the battery and black clamp to the negative terminal.

2. Charge your speaker as you would normally until the battery indicator light turns green. When it is your first time charging the battery, you should leave the battery charging for 2 hours longer after the battery indicator light turns green which will help extend the life of the battery for future uses.

3. Make sure to charge the external battery and the battery inside your speaker at least once every three months so it can maintain it's health and you can use it for many yeas to come.
