Alag Alag Sizes (AA aur AAA Sizes)

Remotes mein aam taur par do tarah ke cells istemal hote hain:

• AAA Cells (Chote Cells): Yeh size mein patle aur chote ہوتے hain. Aaj kal ke zyadatar modern TV, LED, aur AC ke remotes mein yahi patle cells lagte hain.

• AA Cells (Badhe Cells): Yeh thode mote hote hain. Yeh purane remotes, deewar ki gharion (wall clocks), aur bacho ke khilone (toys) mein zyada istemal hote hain.

2. Lambi Umar (Long Shelf Life)

Achhe brands (jaise Duracell, Energizer, ya Toshiba) ke cells ka sab se bada feature yeh hota hai ki agar aap inhein khareed kar ghar rakh lein aur istemal na bhi karein, to yeh 5 se 10 saal tak kharab nahi hote aur apni power barkarar rakhte hain.

3. Leakage Protection (Leak-Proof Design)

Purane zamane ke saste cells aksar remote ke andar hi phat jaate chemical chhorh dete magnetic chemical (acid) nikal aata tha, jis se remote kharab ho jata tha. Aaj kal ke achhe cells Anti-Leak technology ke sath aate hain, jo aapke qeemti remotes ko chemicals se mehfooz rakhte hain.

4. Alkaline vs Carbon Zinc (Power Types)

Market mein do tarah ke chemical wale cells milte hain:

• Alkaline Cells: Yeh thode mehangay hote hain lekin inki power bohot zyada hoti hai aur yeh remote mein saal-saal bhar khatam nahi hote.

• Carbon Zinc (Normal) Cells: Yeh saste hote hain aur kam power wali cheezon (jaise sirf remote ya wall clock) ke liye bilkul theek rehte hain.

5. Constant Voltage (Barabar Current)

Remote ke cells ka feature yeh hota hai ki yeh aakhir tak ek jaisa voltage (takreeban 1.5V) dete hain. Iska faida yeh hota hai ki jab tak cell bilkul khatam nahi ho jata, aapka remote bilkul sahi aur tezi se kaam karta rehta hai.
