Desigur, o functionare continua de peste doi ani si un voltmetru pot spune multe dar, pentru a aprecia calitatea unui acumulator la un moment dat, este necesar un tester dedicat care are posibilitatea de masura cel putin rezistenta interna. In fotografiile urmatoare veti gasi parametrii a doi acumulatori noi de 12V / 9Ah si 12V / 7Ah, asa cum au venit de la producator, inainte de a fi conectati in UPS</span>.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><br /></div><div style="text-align: center;"><span style="font-size: x-large;">12V / 7Ah</span></div><div style="text-align: justify;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimJR2NZz1ndFvnnmL59f0oGihP1BoyNEIdGG051uF3wy82-91N1JYdmrBh96_MA6sP7hP8X_pjOB_LltcZwGDrwGRo-DTwNDdFeX9tbAl91fsNWW785NtilWzCcrPlI_pV9b2AjkZgwimr3IvIEyaFdKTDih_bXj9eq63_4Rfm4Xzn3nSpy1eer-ma/s800/IMG_20220711_122733_568-001.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimJR2NZz1ndFvnnmL59f0oGihP1BoyNEIdGG051uF3wy82-91N1JYdmrBh96_MA6sP7hP8X_pjOB_LltcZwGDrwGRo-DTwNDdFeX9tbAl91fsNWW785NtilWzCcrPlI_pV9b2AjkZgwimr3IvIEyaFdKTDih_bXj9eq63_4Rfm4Xzn3nSpy1eer-ma/w640-h480/IMG_20220711_122733_568-001.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEio8PhxDuv8fCBB983i-1RhrQeT8ZUpTlMMNGhCfRpjJfVwMEYnS_WtwsWlibbSl5kSEA3jYsuYVzFi7njha6MxZQ3pvvQMFEiIWYjcr8-l88ZveY5-HjqPYeQ-E10r4lJucG-4hmuU4XdEJAM-dh1d9w8Jk0MGVE8Fy36l97ll9T1iYSQOjHw346Ll/s800/IMG_20220711_122739_453-001.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEio8PhxDuv8fCBB983i-1RhrQeT8ZUpTlMMNGhCfRpjJfVwMEYnS_WtwsWlibbSl5kSEA3jYsuYVzFi7njha6MxZQ3pvvQMFEiIWYjcr8-l88ZveY5-HjqPYeQ-E10r4lJucG-4hmuU4XdEJAM-dh1d9w8Jk0MGVE8Fy36l97ll9T1iYSQOjHw346Ll/w640-h480/IMG_20220711_122739_453-001.jpg" width="640" /></a></div><br /></div><div style="text-align: justify;"><br /></div><div style="text-align: center;"><span style="font-size: x-large;">12V / 9Ah</span></div><div style="text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDlthJqxgukJCiGUhXAGAvbHxmH3Xv3Pc7bIi4nejuSbf5lbqlLDPvT_KYApieX6D-lMyRk5rxzmYNQ3rxU7nV_zH9szfeTPyGgbshzNkZSiD3c4JKZCi5br7uXSTrrtE0pf2UxI7Id_1e9NJj89pTL3JDuxsu8QH1-9m7U6N_OSQUgIx39HEdXY8m/s800/IMG_20220711_122532_983-001.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDlthJqxgukJCiGUhXAGAvbHxmH3Xv3Pc7bIi4nejuSbf5lbqlLDPvT_KYApieX6D-lMyRk5rxzmYNQ3rxU7nV_zH9szfeTPyGgbshzNkZSiD3c4JKZCi5br7uXSTrrtE0pf2UxI7Id_1e9NJj89pTL3JDuxsu8QH1-9m7U6N_OSQUgIx39HEdXY8m/w640-h480/IMG_20220711_122532_983-001.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh3Sn-Oq5EZQj23zKP-pNtaTXFGspEFnxaLSjucOwAHZqX1n977fGIdpioOrZb9HMYB09d4INqvUD1d7iiuxd_JMQ5CmyZZbYYEnLNtLtoZ1fQNgLJkqnwXHhHYNAHuuAMD767S4nnrhUUsruIzKTNRcWswGYlQgmJXjca2LYUZUJm3goKnxjBHQf5c/s800/IMG_20220711_122545_740-001.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh3Sn-Oq5EZQj23zKP-pNtaTXFGspEFnxaLSjucOwAHZqX1n977fGIdpioOrZb9HMYB09d4INqvUD1d7iiuxd_JMQ5CmyZZbYYEnLNtLtoZ1fQNgLJkqnwXHhHYNAHuuAMD767S4nnrhUUsruIzKTNRcWswGYlQgmJXjca2LYUZUJm3goKnxjBHQf5c/w640-h480/IMG_20220711_122545_740-001.jpg" width="640" /></a></div><br /><span style="font-size: x-large;"><br /></span></div><div style="text-align: justify;"><span style="font-size: large;">Trebuie precizat faptul ca de cele mai multe ori acumulatoarii care nu trec testul sunt uscati. Daca carcasa nu este sparta/deformata, exista posibilitatea de remediere prin adaugarea in fiecare element a unei cantitati de apa distilata urmata de reincarcare, dar revenirea la capacitatea initiala nu mai este posibila. </span></div><div style="text-align: justify;"><span style="font-size: large;"><br /></span></div><div style="text-align: justify;"><span style="font-size: large;"><br /></span></div><p></p>Constantin Rusuhttp://www.blogger.com/profile/12959087644397138179noreply@blogger.com0
