This is a continuation of Using the HLVD Module in Swordfish Basic. Here's a detailed look at using the HLVD module for detecting a low battery as I touched on in the previous artile.
A lot of variables go into the viability of this technique including the battery chemistry, the number of cells, the current drawn from the cells and whether the load is steady or intermittent. Conclusions based on these NiCAD batteries will generally apply to NiMD batteries as well. Li-Ion and Li-PO batteries have some very specific requirements for charging, discharging and maximum and minimum voltage and won't be covered here.
