Na wɔde saa UPS nhyehyɛe yi batere akuw abien no adi dwuma mfe 4 (a battery 12V nkwa nna yɛ mfe 5), na na batere no tumi so atew kɛse. Nanso, ansa na huammɔdi no reba no, na batere no akyi hwɛbea yɛ ade a ɛfata, na na sɛnkyerɛnne biara nni hɔ a ɛkyerɛ sɛ ɛrehuruw.

Bere a wɔasiesie ne capacitor foforo akyi no, wɔsan fii ase yɛɛ UPS nhyehyɛe no. Control logic no kyerɛɛ battery no sɛ ɛyɛ foforo, enti efii ase simma 6 equalized charging na afei ɛdanee kɔɔ float charge so. Nanso, bere a wɔde simma 14 a edi hɔ sɔhwɛ a edi hɔ no, UPS nhyehyɛe no fii ase yɛɛ pɛ wɔ ɔkwan a ɛyɛ pɛ so ara kwa na ama batere no ayɛ adwuma koraa. Esiane batere a wɔde di dwuma mfe 4 nti, na wɔn mu charge retention tumi no asɛe, na ɛmaa float charge current no boroo 1A, ɛkanyan 1A equalized charging threshold set wɔ UPS nhyehyɛe no mu (default bo a ɛwɔ saa model yi mu ne 3~5a float charge current a ɛbɛkanyan equalized charging, nanso esiane biribi nti, na wɔn a wɔhwɛ so no asesa eyi ama 1A). Eyi maa UPS nhyehyɛe no fii ase mpɛn pii fii charging a ɛyɛ pɛ no ase kosii sɛ awiei koraa no, battery open circuit a ɛwɔ mu no gyaee (anyɛ saa a, anka UPS nhyehyɛe no bɛkɔ so ayɛ pɛpɛɛpɛ mpɛn pii, a anka ebetumi ama battery kuw no akyere ogya). Wɔ saa bere yi mu no, batere no yɛɛ anan a ɛkɔ so yɛ pɛ a ɛkɔ so yɛ pɛ wɔ nnɔnhwerew 48 mu (kyinhyia biara gyinaa hɔ simma 1 pɛ nnɔnhwerew 12 biara ansa na wɔresan afi ase ayɛ pɛpɛɛpɛ).
