SLI Batteries (Lead-acid)

Regeneration Guide

The SLI batteries know various quality of make which mostly depends on plates density.

  • Batteries sold under distributor brand at low price, generally have a low density and they are therefore prone to rapid decline.
  • Batteries sold under maker brand are generally more resistant against sulfation
  • OEM batteries are generaly provided by makers to car makes.

The maintenance-free batteries are Calcium doped and they know reduced self-discharge and water loss. Therefore, these batteries get less rapidly sulfated.
