## Claims captured from transcript/contact sheet

The TikTok claims a cheap “battery powder” / Epsom salt method can revive weak lead-acid car batteries and make them last far longer. Captured details:

- Ingredient: Epsom salt / magnesium sulfate.
- Liquid: warm distilled water.
- Recipe stated: one heaping tablespoon Epsom salt mixed into one cup warm distilled water.
- Process stated: pop the caps, treat all six cells, trickle charge overnight, then let the battery rest for three days before reinstalling.
- Claimed reason: the rest period allegedly lowers internal resistance another 15–20% and allows plates to clear.
- Claimed outcome: weak battery may crank again and last longer.

## Safety frame

This must be treated as a risky garage hack, not a general instruction. Lead-acid batteries contain sulfuric acid and can produce explosive hydrogen gas. Many modern batteries are sealed/maintenance-free; AGM, gel, lithium, swollen, cracked, frozen or leaking batteries should not be opened or “treated.”
