[R-390] Batteries

[Johnsay Johnsay via R-390]

In my line of work I purchased pallet quantities of alkaline batteries for use in scientific oceanographic equipment.  These instruments (current meters,  thermistor strings and acoustic mooring releases)  were typically deployed for one and occasionally two years in difficult environmental conditions.  Batteries were frequently in storage for a  year or two before use due to the purchase requisition process.  All batteries were load tested before installation.   My preference based on a variety of operational characteristics were  first to last:  Panasonic Industrial,  Energizer,  Duracell, and Rayovac.   Rayovac was well down the list with quite a few more problems with leakage.  
We did a trial with primary lithium batteries but these tended to have more problems with leakage.   When this happened, due to their chemistries they would totally destroy the instruments.   Tadiran was particularly bad actor in this respect.John,  W8KX
