Battery Cell Covers

Now available with our patented dielectric fluid saver insert, this option allows a battery manufacturer to produce a low maintenance battery. Our insert has been granted patent #8,999,565 by the US Patent Office. During our manufacturing process, this insert is welded in place to produce a hybrid cover. Electrolyte vapor that normally escapes from the battery condenses on the insert and is retained inside the battery. Watering intervals are increased, resulting in lower maintenance costs and more uptime. An independent lab test revealed that our hybrid cover produced up to a 25% water savings over a control group of standard battery covers.

We manufacture battery lids in both standard and custom sizes for battery OEM and battery manufacturers. Click on the links below to view our current drawings (your browser must be set to allow pop-ups). To receive a quote for any custom size, click here to send us an email.
