Description

The Victron Energy 12V 165Ah AGM Deep Cycle is a sealed, maintenance-free VRLA battery built on flat plate Absorbent Glass Mat construction. The electrolyte is absorbed into a glass-fibre mat between the plates, making the battery spill-proof and suitable for mounting in any orientation. Low internal resistance gives strong high-current performance for marine loads such as inverters, bow thrusters and electric winches.

The 165Ah rating is quoted at the 20 hour rate, with 150Ah available at the faster 10 hour rate. Lead-calcium grids and high-purity materials hold self-discharge below 2% per month, so the battery tolerates long periods between charges. Service life is maximised by keeping discharges shallow and recharging promptly with a suitable three or four step charger.

With flat copper terminals, 600A cold cranking and 220 minutes reserve capacity, this battery is a dependable mid-to-large house bank option for cruising yachts and motor vessels.

Why are two capacities, 150Ah and 165Ah, quoted?
Lead-acid capacity depends on discharge rate. The 165Ah figure is the rated capacity at the 20 hour rate (C20), while 150Ah is the capacity at the faster 10 hour rate (C10).
What charge voltages should I use?
Victron specifies an absorption voltage of 14.2 to 14.6V, a float voltage of 13.5 to 13.8V and a storage voltage of 13.2 to 13.5V for a 12V battery, with temperature compensation of -24 mV/°C.
How many charge and discharge cycles can it deliver?
The cycle design life is 400 cycles at 80% depth of discharge, 600 cycles at 50%, and 1500 cycles at 30%. Keeping discharges shallow greatly extends service life.
Does the battery need maintenance?
No. It is a sealed valve-regulated (VRLA) AGM battery and is maintenance-free for life; gas only escapes through the safety valves in the event of overcharging.
Can it be mounted on its side?
Yes. Because the electrolyte is absorbed into a glass-fibre mat rather than being free liquid, the battery is spill-proof and can be mounted in any orientation except inverted.
