Storage technologies vary by application, but most research and development is occurring in the realm of batteries, which compete mainly on cost, battery life, and safety. Lead-acid batteries are the oldest type of rechargeable battery and have a very low cost, but they suffer from a short cycle life.
Teknolohiya Storage mag-iba sa pamamagitan ng application, ngunit karamihan sa pananaliksik at pag-unlad nagaganap sa lupain ng mga baterya, na makipagkumpetensya sa pangunahing sa gastos, buhay ng baterya, at kaligtasan. Humantong-acid baterya ay ang pinakalumang uri ng rechargeable baterya at mayroon ng isang napakababang halaga, ngunit magdusa sila mula sa isang maikling ikot ng buhay.
