Has anyone noticed a loss of capacity on their NiMH packs?
My understanding was that NiMH packs do not suffer from memory effect but, I'm seeing lower voltages out of the packs that are a year old with maybe 100-150 cycles on them than I am seeing out of packs that same battery but newer. I never charge the batteries over 2A (1100mAH batteries) and leave them with about 1/2 charge when storing.
Is this an increase in Internal Resistance causing the voltage loss?
Some reading I've done on it tells me that for storage full charge is detrimental to the cells, where as 1/2 charge and lower storage temps are ideal.
I guess in the scheme of things the NiMH battery prices we see for 18th scale are low by comparison to 10th scale.
I understand that aging on the Lithium Ion and Lithium Polymer batteries is an issue. As these batteries get older their Internal Resistance and thus their voltage and capacity drop.
Doesn't make pricey batteries like the Lithium look so great then. Proves you can't have your cake and eat it too...
Anyone else seeing these problems?
