ABSTRACT
This study aimed to design an organic wet cell using the extracts from Musa paradisiaca (banana) and Citrus mitis (calamansi) to determine the capability of these extracts as substitutes to commercial battery paste. It specifically compared the voltage output and depletion rate of banana-calamansi, calamansi-commercial, banana-commercial and pure commercial pastes. It further determined the significant difference in the voltage output and depletion rate of banana-calamansi, calamansi-commercial, banana-commercial and pure commercial pastes. The researchers designed four set-ups consisting of banana-calamansi, banana-commercial, calamansi-commercial, and pure commercial pastes. The voltage output and depletion rate were then measured and analyzed using One-Way ANOVA and Scheffe’s Post-Hoc analytical tools.
The results of the study show that the three set-ups, namely; banana-calamansi, banana-commercial and calamansi-commercial yielded lower voltage outputs as compared to the pure commercial set-up. Also, these three set-ups yielded higher depletion rates as compared to the pure commercial-set-up. The voltage ouitput of the banana-calamansi set-up was significantly lower than the three other set-ups while the voltage outputs of banana-commercial and calamansi-commercial set-ups had no significant difference as compared to the pure commercial set-up.
There was no significant difference for the depletion rates of the voltage output of the set-ups. the depletion rate was also insignificant between trials of the same set-up.
