大家都知，市場定律：將價就貨。 鉛價升左幾倍，電池嘅electrodes梗係偷薄喇。
新車都轉用細電池，更加容易另Ｄ電打柴。 成日塞車，開冷氣，電池負荷大，也加速電池死亡。有兩年半貨仔，好好架喇！

I was thinking of adding a ultracapacitor in parallel to the battery. it seems it is a viable and budgetary way to prolong the battery life.

Ultracapacitor smooths out the peaks and troughs of current in and out of the battery. Therefore, the maximum charge / discharge current of the battery is decreased. In this connection, the battery life is prolonged.
This technique was also applied to next generation EVs, for better energy recovery from regenerative brake.

There are some 土炮as well
Who want to be a guinea pig to try this?

elvin講舊野, 係咪好似你個tomato電子整流器?
我記得以前舊電用多過兩年, 不過無留意係咪因為佢.

Yes you are right. That device did able to prolong battery life (a bit)
But you usually need far higher capacitance to smooth out the big current especially during cranking.
