House of Batteries: US-based manufacturer of custom, rechargeable batteries, ensuring design, assembly, and testing.
House of Batteries designed and manufactured custom battery packs across all major chemistries, with a particular focus on lithium-based and rechargeable systems. Its custom-power portfolio spanned lithium-ion, lithium polymer, nickel-metal-hydride, and alkaline configurations engineered to customer specifications.
The company supplied these custom pack solutions to original-equipment manufacturers in medical, military, aerospace, and industrial markets, pairing design engineering with battery assembly and testing. Its capability covered both primary and rechargeable chemistries, allowing it to address a wide range of voltage, form-factor, and runtime requirements.
House of Batteries was acquired by Solid State PLC, with the transaction announced on 16 May 2022 and completed in August 2022. Following the acquisition, the House of Batteries operations were folded into the Custom Power brand that Solid State PLC uses for its United States battery-pack manufacturing.
The original houseofbatteries.com domain now redirects to custompower.com, and the acquired operation continues from the same Fountain Valley headquarters at 10910 Talbert Avenue. This reflects a consolidation of the Solid State PLC battery businesses under a unified Custom Power identity rather than an independent continuation of the House of Batteries brand.
House of Batteries operated from a 36000-square-foot facility and maintained an inventory of more than two million batteries to support rapid custom-pack fulfillment. It held ISO 9001 certification and ITAR registration, qualifying it for defense and aerospace manufacturing work that requires strict quality and compliance controls.
The company was also recognized as a woman-owned business, broadening its eligibility for supplier-diversity programs among government and large-enterprise customers. Together these credentials supported its positioning as a domestic, compliant custom battery-pack manufacturer for regulated industries.
