[RE-wrenches] Interstate L-16 vs Trojan L-16REB

[Darryl Thayer]

The reason the lead calcium does not have the stratification problem as much is the chemistry does not self discharge as fast.  The lead antimony plates are strong but the antimony leads to self discharge.  this is so slow that it allows the battery to stratify, and therefore it needs more cycling and more equalization.

Carl,

I've got two sets of Surette lead-calcium in an off-grid test system.
The electrolyte is H2S04 .. sulfuric acid.

The internal construction of these batteries is more open than I've
seen in other L16 style cells (more space between the plates),
which may (or may not) lend itself to lessening of stratification
issues.
