R-CAP

Rolls R-CAP flip-top battery caps prolong battery life by saving water. These caps will reduce water loss by 50% to 60%, provided your charging equipment is properly regulated. The sulfuric acid droplets being carried by the escaping gasses will be reduced by nearly 100 percent.

  • Engineered and designed to encompass all areas of concern - ease of inspection, watering and safe completion of equalization charges.
  • Battery-top moisture reduction. Electrolyte retention within cells. Extended watering intervals.
  • Fume-free environment, as well as flame and/or spark retardant characteristics.
  • An injection molded flip-top vent cap allows safe and efficient maintenance during the routing servicing of industrial, semi- industrial and golf cart batteries.

No Need To Remove The R-CAP

Ideal for installations with limited access, in cramped spaces or simply for convenience, the R-CAP easily opens to allow inspection or watering of cells and snaps closed for a tight fit.

Less Frequent Watering

Extended watering intervals are achieved as very little electrolyte passes through the moisture return medium and hydrophobic cindered disc combination.

Longer Lasting Batteries

Residual gases which escape through the moisture retention medium during the charge cycle carry fewer electrolyte- laden droplets than traditional caps, assuring that electrolyte gravities are stabilized within the battery cell(s) – resulting in consistency of intended cell voltage and capacity characteristics.

Canadian and the best

Canadian company, and these batteries are built like tanks. Hope you don’t need to move them around much but they are worth the price. I was recommended them and I have been telling everyone to get them.

Vent caps

Not much to review, I put them on at the end of the season and disconnected the batteries. The fit, delivery was fast.

Battery tops have never been cleaner. No mist or dribbles on them. Haven't been on long enough to know how much less watering I'll have to do.
