- Gel cells are lead/acid storage batteries with a semisolid
- (gelatinous) acid electrolyte. You can't spill acid from them.
- Neither type is sensitive to cold (unless you live in Minnesota...)
-
- Neither type should be stored discharged, because the formation
- of insoluble sulphates on the lead make the battery difficult to
- charge (and raise its internal resistance, permanently).
-
- I use gel cells on my bike; it works out fine.
