Mighty Max Battery MAX3464134 battery filler jug

SKU CH-8CW1-G3ERZ

A 2 qt acid-proof polyethylene jug that automatically stops filling wet-cell batteries at the correct level and prevents after-drip

  • Automatically stops filling at correct cell level preventing overfill
  • Double-action fast-flow valve tip eliminates after-drip mess
  • Acid-proof polyethylene construction withstands battery fluids safely
  • Two-quart capacity handles multiple battery servicing tasks
  • Reduces surface discharge caused by wet battery tops

Battery Filler Jug for Wet Cells

The Mighty Max MAX3464134 is a two-quart polyethylene jug designed to add distilled water to flooded lead-acid batteries. Its acid-proof construction withstands the corrosive fluids found in automotive and mobility power systems. The integrated valve tip stops flow automatically when the cell reaches the correct level, preventing overfilling and surface discharge.

Replaces Funnels and Manual Topping Methods

This jug upgrades from open funnels or squeeze bottles that rely on guesswork and often spill electrolyte. The automatic shut-off and anti-drip valve make the jump worthwhile for anyone who services multiple batteries and wants a cleaner, faster routine without acid splashback. It is not suited for sealed AGM or gel batteries that must never be opened.

Limits of Gravity-Fed Acid-Resistant Polyethylene

The jug relies on gravity feed and a mechanical float valve, so flow rate drops as the fluid level falls and the tip must sit squarely on each cell. Polyethylene resists sulphuric acid but can degrade under prolonged UV exposure or extreme heat. No pump, meter or pressure regulation is built in, so precise electrolyte specific-gravity adjustments still require separate instruments.

Questions about this item

What capacity jug fits a standard wet-cell battery for topping up?

The 2 qt. acid-proof polyethylene jug is sized for adding water to wet batteries without overfilling.

How does the double-action fast-flow valve tip prevent after-drip during filling?

The valve shuts off automatically when the cell reaches the proper level, stopping flow and eliminating after-drip.

When should the jug be replaced if used regularly with battery acid?

Replace the jug if the polyethylene shows cracking, clouding, or the automatic shut-off valve no longer seals cleanly.
