T&G TG 113A is one of my favorite T&G Speakers because the bass is better than the other T&G models under $5USD. But the playtime will let you down, so I will show you in this video how to do T&G TG 113A battery upgrade to a much higher capacity battery (18650). This will increase the playtime from 2 hours to 8 hours (50% volume). At the same time will take a look inside the T&G TG 113A and its electronics and passive radiator.

I have tested this at around 35% volume and it went more than 12 hours straight. Remember its not just the capacity, its also depends on what kind of music you play because some have heavier bass.

Be careful with cheap batteries because they don't last long, they never did anyways.
