LiFe aku "sissetöötamise" tähtsus

Post by lauri »

Avastasin täna kurbusega, et üks väga vähe kasutatud LiFe vastuvõtja aku oli üle talve seismisega täiesti kasutuskõlbmatuks muutunud. Seisis kenasti ~50% laetusega. Elemendid olid punnis ja mahtuvust alles ~20%. Veider, et just toatemperatuuril seistes oli aku täiesti hukka läinud.

Tundub, et LiFe akude puhul on eriti tähtis nende sissetöötamine. Miskit muud, kui sissetöötamise puudulikkust ei oska küll enda akupaki hukkamineku põhjuseks pakkuda.
Brand new LiFePO4 batteries have been found to fail prematurely if they are deep discharged below 33% capacity too early. A break-in period of 20 cycles is currently recommended. While testing has shown that this battery can be charged at up to 3C rates, it is recommended that this battery not be charged at rates higher than 1C to maximize the lifespan of the battery. Additionally, LiFe batteries should not be discharged below 2.5V per cell to avoid pre-mature failure and maximize battery life span.

We also recommend you REMOVE the batteries from your cars or radios when you are done, or at least unplug them to avoid accidental over discharge if the unit is left on.

IMPORTANT:
1) You will need a LiFe specific charger to charge the pack (NiMH, NiCD or Li-Poly only chargers WILL NOT WORK!)
2) You must not discharge the LiFe battery pack below 33% capacity during the break in period or below 2.5V per cell after break in.
3) It is not recommended that you charge this LiFe battery pack at amp rates higher than 1C.
4) Read the instructions carefully before operating this battery.
