SpeedCaps™ For Your Deep-Cycle Battery
U.S. Battery SpeedCaps™ Go Beyond Venting Deep-Cycle Battery Cells
The vent caps used on deep cycle batteries are designed to allow the escape of gases formed inside the battery when it is being charged and to limit the escape of electrolyte in normal operation. The vent caps are also designed for easy removal to visually check the electrolyte level in the battery and to add water as necessary. They also allow for the insertion of a hydrometer to check the battery’s state of charge. During regular maintenance that requires removing and reinstalling the vent caps, there is a possibility that the vent caps may not be properly reinstalled. This could allow electrolyte to spill over onto the battery and cause corrosion on terminals and surrounding areas.
To improve on the standard battery vent cap, U.S. Battery SpeedCaps™ are designed with a cantilever-style closure that is attached to three or four battery cell caps. This design allows all the caps to be easily removed with a single twist. The design not only makes the removal of the battery caps easier, but it also ensures that they are properly seated when being replaced. The locking ramp on top self-adjusts to maintain compression between the sealing gasket and vent well surface for the life of the battery. SpeedCaps™ are designed to make your job of battery maintenance as hassle-free as possible while also maintaining a proper seal and gas venting during use.
Proper venting is critical during charging when gas is being generated within the electrolyte and bubbles to the surface, helping to mix the electrolyte. To prevent electrolyte from escaping past the vent caps, U.S. Battery SpeedCaps™ feature 0.750-inch diameter porous discs that assure proper venting while maintaining flame retardance to prevent gas ignition inside the battery. They also have four separate vent holes that decrease backpressure and prevent internal pressure buildup.
Since vent caps are removed and replaced frequently during regular battery maintenance, U.S. Battery SpeedCaps™ are designed with a larger diameter flange. The enlarged flange ensures even pressure on the surface of the sealing gasket while maintaining a tight fit between the barrel and cylinder to eliminate side-to-side movement and the chance for misalignment of the gasket onto the sealing surface.
To prevent spilling of the electrolyte during vehicle movement in golf carts, aerial platform lifts, RVs, boats, etc., the SpeedCap™ design also features a double-sided internal baffle with multi-directional channels and a sloped center hole return drain, all designed to route battery electrolyte back into the cell.
With all these safeguards in place, U.S. Battery SpeedCaps™ are an example of one of the many details the company adds to its products to ensure they provide optimum performance and cycle life compared to other deep-cycle batteries on the market.

I can’t seem to get caps off. Moved cantilever to neutral area but won’t release
Hi Mike,
Our Engineer recommends gently rocking the cap back and forth, with it in the neutral position. It may be stuck due to buildup from use. As long as the cantilever is in the neutral position, you will not harm the valve by rocking it. Take a look at these images for reference.

I recently purchased a 2013 EZGO RXV golf cart. It has a 48 volt system. (4- 12 volt batteries). It has new batteries. 2 of the batteries are US Batteries and 2 are Trojan. I checked out your website and saw the speed caps which I would like to get for my 2 US batteries. I contacted 2 of your distributors that are close by but neither carry the speed caps. Because my batteries are 12 volt, I’m guessing I would need 2 speed caps per battery, each speed cap covering 3 cell caps. I’m hoping you can help me with where to purchase and the cost. Thanks, Walt

My golf cart is 48 volt. 6, 8volt batteries. I just replaced the batteries that have the spin caps. Do to the configuration of the battery wiring in series the connecting rods to the caps prevent a proper installation of the battery cables. Can the spin cap rods be removed or can I get individual cap for each battery fill hole. Either or option would sure make it easier and cleaner set up for the battery cables.
Hi Brad,
Where are you located? I would be happy to put you in contact with someone that can help get you the individual caps for your batteries.

Speedcaps stuck
Lever will not budge
Hi D,
Our engineers recommend using pump pliers to unstuck a lever by providing an easier grip. If facing the front of the battery, negative terminal on the left-hand side, use the channel locks to turn the SpeedCap levels counterclockwise. Do not use the pliers to pry the SpeedCap off.

I live in Tavares, FL. 32778 and need Speed Caps for 6 of your 8 volt batteries. US 8VGCi
Hi Robert,
Thank you for choosing U.S. Battery products!
The US 8VGCi is designed to be compatible with select OEM watering kits; because of this, the cell spacing is different than our other 8V batteries and will not work with the SpeedCaps. Our bayonet caps are compatible with the 8VGCi would you like me to arrange to send some of those to you?

I have speed caps on the batteries in my golf cart. I don’t have much strength in my hands. I was wondering if there is a wrench of some type available that would let me apply additional leverage To the finger part to remove the caps ? I am hesitant to use the wrench on the caps themselves.
Thanks for your help. Bud
Hi Bud, Our engineers recommend using an insulated pair of pump pliers to get some leverage on the speedcaps. Take a look at the video they made showing the removal of the Speedcaps.
