I have an old emergency light with an almost dead 6 volt 4 amp battery inside, so I switched it to 2 x 18650 (3.7v, 4800mah) = 7.4 volt 4800mah.
At first everything worked out fine, until it started to loose power very quickly. Now if I charge it for 2 days and try to use it at low power it only lasts for almost 1 minute.
I'm guessing the issue is with a capacitor, but I still haven't checked.
Any suggestions to what would the problem be? and if replacing the 7.4v batteries with 6v ones would fix the problem?
