Mphamvu ya batire imatanthawuza mphamvu yomwe batire ingatulutse ikatuluka, nthawi zambiri imawonetsedwa ndi W·h kapena kW·h. Mphamvu ya batri imagawidwa kwambiri m'mitundu iyi:
(1) Mphamvu Zongoganizira
Kungoganiza kuti batire ili mumgwirizano pakutha, voteji yake yotulutsa imasunga mtengo wa mphamvu ya electromotive (E), ndipo kuchuluka kwa zinthu zomwe zimagwira ntchito ndi 100%, mwachitsanzo, kutulutsa mphamvu ndi mphamvu yongoyerekeza, ndiye mphamvu yotulutsa mphamvu pansi pazimenezi ndi mphamvu yamalingaliro W₀, mwachitsanzo.
(2) Mphamvu Zenizeni
Mphamvu zenizeni zimatanthawuza mphamvu yomwe batire limatulutsa pa nthawi yotulutsa. Mwachiwerengero, ndizofanana ndi kuphatikizika kwamagetsi enieni a batire, kutulutsa kwapano, ndi nthawi yotulutsa, mwachitsanzo.
Muzochita zauinjiniya, mphamvu yeniyeni ya batire nthawi zambiri imayerekezedwa pogwiritsa ntchito mphamvu zonse zovoteledwa za paketi ya batri komanso mphamvu yamagetsi yotulutsa batire.
Chifukwa chakuti zinthu zogwira ntchito sizingagwiritsidwe ntchito mokwanira, mphamvu yogwiritsira ntchito batri nthawi zonse imakhala yochepa kuposa mphamvu yake ya electromotive, choncho mphamvu yeniyeni ya batri nthawi zonse imakhala yochepa kuposa mphamvu yake yongoyerekeza.
(3) Mphamvu Zonse
Mphamvu zonse zimatanthawuza mphamvu zonse za magetsi zomwe batire limatulutsa pa nthawi ya moyo wake, zoyezedwa ndi W·h.
(4) Mphamvu Yopangira
Mphamvu yolipiritsa imatanthawuza mphamvu yamagetsi yomwe imalowetsedwa mu batire kudzera pa charger, yoyezedwa ndi W·h.
(5) Kutulutsa Mphamvu
Kutulutsa mphamvu kumatanthawuza kutulutsa mphamvu yamagetsi ndi batire panthawi yotulutsa, yoyesedwa mu W · h. Mphamvu ya batri, kapena mphamvu yomwe unit mass kapena voliyumu ya batri imatha kutulutsa, imatchedwanso mass energy. M'magalimoto amagetsi, mphamvu yeniyeni ya batri imakhudza kulemera kwa galimoto yonse ndi kayendetsedwe kake, pamene mphamvu ya volumetric imakhudza malo a batire. Mphamvu zenizeni ndi chizindikiro chofunikira kwambiri pakuyerekeza magwiridwe antchito amitundu yosiyanasiyana ya mabatire. Mphamvu zenizeni zimagawidwa m'malingaliro enieni (W₀) ndi mphamvu yeniyeni yeniyeni (W').
Mphamvu zapadera zongoyerekeza zimafanana ndi mphamvu zongoyerekeza, kutengera mphamvu zomwe zimatha kutulutsidwa pomwe ma unit mass kapena voliyumu ya batri yotulutsa mphamvu yatha. Mphamvu zenizeni zenizeni zimafanana ndi mphamvu zenizeni, zomwe zimayimira mphamvu yeniyeni yomwe imatulutsidwa pamene yuniti ya yuniti kapena voliyumu ya ma reactants a batri yatha. Imadziwika ndi chiŵerengero cha mphamvu yeniyeni ya batri ku misa (kapena voliyumu).

Mu chilinganizo, C--amayimira kuchuluka kwa batri; V - imayimira kuchuluka kwa batri. Chifukwa cha zinthu zosiyanasiyana, mphamvu yeniyeni yeniyeni ya batri ndiyotsika kwambiri kuposa mphamvu zake zongoyerekeza. Ubale pakati pa mphamvu zenizeni ndi zongoyerekeza zitha kuwonetsedwa motere:
Mu chilinganizo, K_E ikuyimira mphamvu yamagetsi; K_B imayimira kuchita bwino; ndipo K_m imayimira mphamvu zambiri.
Pogwiritsira ntchito mabatire amagetsi m'magalimoto amagetsi, mphamvu yeniyeni ya paketi ya batri imakhala yochepa kusiyana ndi mphamvu yeniyeni ya maselo a batri chifukwa kukhazikitsa batire kumafuna mabokosi a batri ofananira, mawaya olumikiza, zipangizo zamakono ndi zotetezera magetsi, ndi zigawo zina. Mphamvu yeniyeni ya paketi ya batri imawerengedwa ndi kuchulukitsa mphamvu yeniyeni ya maselo a batri payekha ndi chinthu choyikapo. Zomwe zimayikidwa pa batri wamba ndi 0.6 mpaka 0.8. Pamene mlingo wa mapangidwe a paketi ya batri ukuwonjezeka, kuphatikiza kwa paketi ya batri kumawonjezeka. Chifukwa chake, mphamvu yeniyeni ya batire paketi nthawi zambiri imakhala chizindikiro chofunikira cha magwiridwe antchito a batire. Nthawi zambiri, mphamvu yeniyeni ya batire paketi ndi yotsika ndi 20% kuposa mphamvu yeniyeni ya ma cell a batri.
