How to Choose the Correct Sleeve Size

(Click to enlarge image.)

Choosing the correct sleeve is important to ensure effectiveness.

1. ENERGY CONTAINMENT RATING / WATT HOURS
First, determine energy storage requirements. Battery watt hours should be printed on the battery or are available from the manufacturer. Your battery’s listed energy in watt hours must be less than or equal to the sleeve ECR (Energy Containment Rating). NEVER use a sleeve that is not rated for your battery’s watt hours, regardless of the battery’s dimensions. (See image below.)

2. FIT

DIMENSIONS
Next determine fit. Determine the length (L) by measuring end to end. The best way to find the perimeter (P) is with a flexible tape measure wrapped around the widest part of the battery. Alternately, you may determine approximate perimeter using the following formula: (width + height) x 2 = perimeter

Use the chart above to find the recommended sleeve size for your battery.
