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.
