Deka — family-specific support.

Identity and scope

Purchase policies below are a dated source review, separate from individual product specifications and price observations.

Manufacturer/brand, seller and installation provider are separate roles. A merchant profile does not certify that every product is made by that merchant. Affiliate approval and endorsement are not established by these links.

Catalog Deka includes both Deka Solar/MK lead-acid and Deka Duration lithium. Family/model verification is required.

MK Battery homepage, energy-storage page and contact attempt returned 403; no bypass attempted.

No general Deka logo was retrieved. East Penn or MK corporate marks are not silently substituted.

A currently applicable warranty issuer or legal equivalence between families remains unknown.

Identity

The official Deka Solar gel-battery manual identifies East Penn and MK Battery support branding. The catalog also contains Deka Duration lithium models; the shared Deka label does not establish identical manufacturers, claims terms or warranty coverage across those families.

Warranty handling and support

Not verified for this manufacturer/brand and catalog scope.

No applicable, current model-specific warranty terms or claim procedure were verified for every Deka catalog family. MK Battery pages returned 403. Do not apply a general East Penn automotive/lead-acid warranty to Deka Duration lithium.

No general purchase policy source assigned. · reviewed 2026-11-07

Duration identity

MK Battery’s official corporate brochure lists Deka Solar and Deka Duration as separate battery brands/technologies, with Duration using LFP chemistry. This supports family distinction, not a legal warranty-obligation transfer or a term for DD100/DD300/DD460 models.
