High-current discharge applications demand a battery capable of sustaining deep cycling without accelerating degradation. The Victron Energy Blue Power AGM Deep Cycle Battery 12V 165Ah (BAT412151085) addresses this requirement through valve-regulated lead-acid AGM technology engineered specifically for sustained power delivery to inverters, thrusters, winches, and comparable high-draw commercial installations.
Victron Energy's AGM construction delivers very low internal resistance, enabling high current discharge rates whilst maintaining stable voltage output. The sealed, valve-regulated design eliminates electrolyte maintenance and allows installation in confined or poorly ventilated spaces. The rated design life of 7–10 years reflects the quality of materials and manufacturing disciplines applied across the Blue Power AGM range.
The battery measures 510mm × 200mm – 280mm (L × W × H) and weighs 44.5kg. It is fitted with threaded M8 insert terminals; polarity should be confirmed from the product label prior to installation. No direct cross-reference is supplied. Start-stop compatibility is supported by the AGM technology, though confirmation from the product label is advised for each application.
This product is offered alongside companion variants BAT412201085 and BAT412124081, providing alternative capacity options within the same Blue Power AGM family.
Supplied with a 2-year manufacturer warranty. Standard delivery: 1–3 working days within UK mainland. 30-day returns.
VRLA AGM: design life 7-10 years VRLA GEL: design life 12 years
The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches. The GEL model range offers best deep cycle durability and overall longer life. The use of high purity materials and lead calcium grids ensure that for both AGM and GEL products have particularly low self-discharge so that they will not go flat during long periods without charge. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals. The batteries are compliant with both CE and UL specifications in ABS fireproof containers and come with Victron's 2 year world-wide warranty.
