Батареянинг технологик хусусиятлари ҳам нархини белгилайди. Кўп батареяларда турс-амали етишмаса, улар электр арбангизнинг доимий ҳаракатини таъминлаш учун керакли энергияни беролиши керак. Батарея ҳисоб-киритиш таквими ва ёқилғини қайта тўлдириш имкониятини ҳам кўриб чиқиш лозим.

Therapeutic modalities, such as ultrasound machines and electrical stimulation devices, are also vital components of physical therapy equipment. Ultrasound therapy helps reduce pain and inflammation while promoting tissue healing through the application of sound waves. Electrical stimulation devices, on the other hand, can aid in muscle re-education and pain relief by sending electrical impulses to stimulate nerves and muscles. These modalities are often used alongside exercise to enhance overall treatment outcomes.
