Acumulatori din gama Eneloop de cea mai inalta calitate tehnica retin curentul pentru o perioada mare de timp.
Isi pastreaza 75% din capacitate chiar si dupa 1 an de stocare ( nefolosinta )!!!
Se pot folosi pana la temperaturi chiar de minus 20 grade Celsius!!!
Pre-incarcati energie solara!!!
* Face mai multe poze digitale decat cel mai bun NiMH, caci pastreaza tensiunea de 1.2 V pana aproape de descarcarea totala, pe cand la NiMH tensiunea scade sub 1.1 V si chiar 1 V cand inca mai au jumatate din energie nefolosita. Majoritatea apartelor foto digitale semnalizeaza \'battery low\' la 1.1 V pe baterie si se inchid la 1 V;
* Face de 4 ori mai multe poze digitale decat cea mai buna baterie alcalina.
* Ideal iarna, functionand la fel de bine la temperaturi mici sau chiar negative, fata de alcaline sau NiMH ce isi diminueaza drastic capacitatea
* Fabricat in Japonia, de catre SANYO, liderul mondial in tehnologia si productia de acumulatori.
Eneloop Pret PROMO
The low self-discharge nickel-metal hydride battery (LSD NiMH) was introduced in November 2005. These batteries were developed by Sanyo who called them Eneloop Subsequently, other manufacturers also offered LSD NiMH.
This kind of battery reduces self discharge and, therefore lengthens shelf life compared to normal NiMh batteries . By using an improved electrode separator and improved positive electrode, manufacturers claim that the batteries retain 70 to 85% of their charged capacity after one year when stored at 20 °C (68 °F). Standard NiMH batteries may lose half their charge in the same time period. Retention of charge depends a lot on the battery's impedance or internal resistance (the lower the better), and on the size of the battery as well as the mAh rating.
High quality separators are very important for battery performance. Thick separators take up space and reduce capacity, while providing a low-tech way of reducing self discharge, while thin separators tend to raise the self discharge rate. Some batteries may have overcome this obstacle with more precise manufacturing techniques and by using a more advanced sulfonated polyolefin separator.
When compared to regular NiMH batteries, low self-discharge types are most useful when more than three weeks elapse between charge and discharge to empty, on average, or to ensure that stored devices are usable several weeks after charging of batteries. Specifications for the self discharge rate are not always clear or widely published, and virtually any LSD may claim to maintain some level of charge after 12 months. A non-LSD battery typically self discharges at a rate of about 20% within the first 24 hours, then from 1% to 4% per day thereafter.In devices not accurately calibrated to closely predict battery level, run-times for LSD NiMH batteries can be as good or even better than normal cells with higher rated capacity, because the slightly higher operating voltage doesn't trip a device's under-voltage shut off circuit.
Batteries with low internal resistance waste less energy and capacity on self-heating during rapid discharge and recharge. Low self-discharge NiMH batteries typically have significantly less internal resistance than traditional NiMH batteries.
There are many brand names for LSD NiMH batteries. Most manufacturers produce only size AAA and AA batteries, and most low self discharge batteries are sold in these sizes. Larger size C and D cells are available, though some are merely AA cells inside a C/D-sized case. Maha offers an LSD "D"-cell called the "Imedion" self-rated at 9500 mAh, Accupower offers the "Acculoop" self-rated at 8500 mAh, and Tenergy offers the "Centura" self-rated at 8000 mAh.
