Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

Engineered to meet the requirements of the power industry, the industry leading features inherent to the PowerSafe 3CA-5M battery make it one of the best in the market. The CA-M battery features antimony plates which demonstrate maximized performance in cycling applications, allow the battery to tolerate high temperatures and along with thick positive grids make the CA-M series of batteries one of the most rugged in the market. The jar design allows for more free electrolyte enabling the CA-M battery to be offered with 100% initial capacity.

Designed for easier maintenance, all of the posts and connectors reside above the cell cover meaning maintenance routines including cell monitoring and measurements are simplified. The CA-M series of batteries also includes a Slide LockTM post seal that allows for natural plate growth over time. The innovative tongue-and-groove jar-to-cover seal provides reliability with a robust airtight seal. Combine the standard square plate design which enhances high rate performance and the multi-cell construction that reduces maintenance time, it is no surprise that the CA-M battery has long set the standard to which all other batteries are compared.
