Manta SPK204 FM Bluetooth Speaker Battery Upgrade to 2600mAh Samsung & Adding 6.8µF Capacitor

Hello, I bought a Manta spk204 Fm bluetooth speaker and there is a 1000mah battery inside and I want to replace it with the samsung battery which I bought and it has 2600mah
And for a 4-woofer 4ohm 5w wants to give a 6.8 micro electrolytic capacitor
And now the question is whether the battery will keep the speaker alive longer and whether nothing will happen
1. And and how you need to solder this capacitor
Serial or parallel?
I know it should be + to + a -do-
2. And I also thought to mount an old battery there and connect to a new one and the power would be 3600mah
Is this an option?
I am sending pictures of the center and a new battery

You can change the batteries (you can pair them only the same), but why do you need this capacitor ??

Are you sure you mean woofer? A capacitor is used for the tweeter (connected in series with the loudspeaker) to filter out harmful signals from this low-frequency loudspeaker. But it's definitely not a polarized electrolyte! I can't see the tweeter, so I will repeat the colleague above - WHY DO YOU HAVE THIS CAPACITOR?

I would like to get the bass separated from the speaker

It's good as you can exchange thanks for the answer and the capacitor wants to separate the low tones from the high in the speaker as it could

At the cost of cutting out the bass? At least weird. For such capacity, you will at most "screech".
