Victron 12V 8Ah AGM Deep Cycle Battery | BAT212070084

The Victron Energy 12V 8Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery rated at C20 capacity. It suits small off-grid systems, UPS applications and solar charge storage, or anywhere a compact, reliable AGM cell is needed. The absorbed glass mat construction removes the need for electrolyte topping and allows installation in any orientation.

Key features of this deep cycle battery

• Voltage and capacity, 12V nominal, 8Ah rated at the C20 discharge rate.
• AGM construction, sealed, valve-regulated and maintenance-free.
• Deep cycle design, tolerates repeated charge and discharge cycles better than standard standby batteries.
• Mounting flexibility, can be installed in any orientation thanks to the sealed, spill-proof build.
• Weight, 2.32 kg, suitable for space-constrained enclosures and portable equipment.

Product overview

AGM batteries absorb the electrolyte into a fibreglass mat separator rather than holding it as free liquid. This makes them spill-proof, reduces gassing under normal charging and lets the battery be mounted on its side or end if the installation calls for it. The valve-regulated design means no periodic water top-up, useful in remote or unattended sites.

The C20 rating measures the 8Ah capacity over a 20-hour discharge period. Drawing current faster than this reduces usable capacity, which is normal for lead-acid chemistry. For small solar systems, alarm panels, UPS units and similar low-draw uses, 8Ah C20 is a realistic working figure. At 2.32 kg it is easy to handle and transport without lifting equipment.

This battery works directly with Victron charge controllers and inverter-chargers, and the standard 12V AGM chemistry is also compatible with any charger set to an appropriate AGM profile. Correct charge voltage settings matter for cycle life.

Applications

• Small off-grid solar storage where a compact 12V battery is required.
• UPS and standby power for alarm panels, routers and control equipment.
• Portable power packs and field equipment.
• Caravan, motorhome and marine auxiliary power where space and weight are limited.
• Replacement battery in existing 12V AGM installations.

Installation notes

Charge with a charger set to an AGM profile. Do not use an unregulated charger or a flooded lead-acid profile, as incorrect voltages shorten battery life. Integration into solar or inverter systems should be carried out by a qualified electrician or accredited installer. Keep terminals protected against short circuit during handling and installation.
