Schimbare acumulatori MP4 player

Recommended Posts

Guest Red9

Salut!
As avea nevoie de putin ajutor: Detin un MP4 player de la eBODA de ceva timp, inca functional, dar ai carui acumulatori sunt terminati.
Si as vrea sa-i inlocuiesc.
Arata cam asa:

Totusi 750 mAh imi sunt insuficienti.

Intrebarea mea este urmatoarea: As putea inlocui cu asa ceva??

Daca da, trebuiesc inseriati, corect? Cum pot face?

Sunt incepator, dar invat destul de repede. (deci nu aruncati cu pietre in mine daca nu stiu notiuni de baza! Posted Image )

Multumesc anticipat!!! Posted Image

Da se poate inlocui dar acumulatori vin in paralel nu in serie, la acumulatori de la telefoane se da jos placuta cu piese si se lipeste direct pe bornele acumulatorului dar ai grija cind scoti placuta cu piese sa nu rupi clemele ca dupa aia nu mai ai de unde lipi firu + si -

 

uite capacul ala trebuie dat jos cu tot cu placuta cu piese aceia incercuit cu rosu

acumulatorii de schimb trbuie sa fie identici ,la ineriere se tine cont de + si -,daca nu sunt marcati acumulatorii vechi trebuie idrntificate bornele cu un multimetru.

atentie !

unele capsule cu Li-ion au borna + la capsula si minusul izolat,

daca acumulatorii vechi au protectie si cei noi se vor monta tot cu protectie.

Aha, deci dau jos placuta de pe acumulatorii de telefon.

Ok, dar daca as incerca sa lipesc contactele direct la + si la -? Afecteaza acumulatorul? 

 

Cei 3 din poza a 2a sunt noi si identici. Ma gandeam ca 2790 mAh suna mai bine decat 750. Ca durata.

 

O schema de legare in paralel? Tot pe Google presupun.

Pai legarea in paralel e banala: conectezi plusurie intre ele(3+ in cazul tau) si minusurile intre ele (3-).
