Ce \u00eenseamn\u0103 mAh la o \u021bigar\u0103 electronic\u0103 \u0219i c\u00e2t spune despre autonomia bateriei?<\/span><\/h1>\n

mAh \u00eenseamn\u0103 miliamper-or\u0103 \u0219i exprim\u0103 capacitatea nominal\u0103 de sarcin\u0103 a bateriei.<\/strong> O baterie de 1500 mAh are o capacitate nominal\u0103 cu 50% mai mare dec\u00e2t una de 1000 mAh, dar asta nu \u00eenseamn\u0103 automat 50% mai multe ore sau pufuri. Autonomia unei \u021big\u0103ri electronice depinde \u0219i de puterea folosit\u0103, cartu\u0219, durata \u0219i frecven\u021ba inhal\u0103rilor, eficien\u021ba electronicii, temperatura \u0219i starea bateriei<\/strong>. mAh nu indic\u0103 nici viteza de \u00eenc\u0103rcare. Pentru a compara corect dou\u0103 POD-uri trebuie citite \u00eempreun\u0103 mAh, wattajul efectiv, cartu\u0219ul folosit \u0219i specifica\u021bia de \u00eenc\u0103rcare<\/strong>, nu doar cifra bateriei.<\/p>\n

Ce \u00eenseamn\u0103, de fapt, mAh?<\/h2>\n

mAh este abrevierea pentru:<\/p>\n

miliamper-or\u0103<\/strong>.<\/p>\n

1000 miliamperi-or\u0103 \u00eenseamn\u0103:<\/p>\n

1000 mAh = 1 Ah<\/strong><\/p>\n

Prin urmare:<\/p>\n

Ampere-or\u0103 este o unitate de sarcin\u0103 electric\u0103\/capacitate<\/strong>, definit\u0103 prin curent \u00d7 timp. NIST indic\u0103 \u0219i echivalen\u021ba 1 Ah = 3600 coulombi.<\/p>\n

\u00centr-un exemplu electric idealizat, o baterie de 1 Ah ar putea furniza 1 A timp de o or\u0103.<\/p>\n

Dar aici apare partea important\u0103:<\/p>\n

o \u021bigar\u0103 electronic\u0103 nu func\u021bioneaz\u0103 la curent constant timp de o or\u0103.<\/strong><\/p>\n

Bateria alimenteaz\u0103 dispozitivul \u00een impulsuri de c\u00e2teva secunde, iar electronica regleaz\u0103 tensiunea \u0219i curentul necesare coilului.<\/p>\n

De aceea, mAh este o valoare de capacitate<\/strong>, nu un cronometru.<\/p>\n
