Victron Energy AGM Telecom Batteries (VRLA, Front-Access)

The Victron AGM Telecom battery is a heavy-duty, deep-cycle AGM with front-access terminals and a tall, narrow footprint. Designed for telecom racks, that same shape makes it an excellent space-saver in tight marine and vehicle installs - it slides into narrow lockers and stands where a standard wide battery won't fit, with the terminals reachable from the front. Sealed, maintenance-free, and a true drop-in (no BMS).

Who it's built for

• Tight-space marine and RV installs - the narrow case and front-access terminals fit lockers and racks where a conventional battery can't go.
• Telecom and backup power - the application it was designed for: rack-mounted standby power with a 12-year float design life.
• High-current loads - low internal resistance and very high cranking and short-circuit current suit demanding starting and inverter loads.

Why the Telecom AGM

Front-access terminals, narrow footprint

Terminals are on the front face and the case is tall and slim, so the battery racks neatly and is easy to service in a confined space - a genuine floor-space saver on board.

Very high current capability

Low internal resistance gives strong charge and discharge performance, with cold-cranking amps up to 1,800 A and short-circuit current up to 6,000 A on the 200 Ah.

Long float and cycle life

12-year float design life at 20 C, plus a solid cycle life (over 500 cycles at 50% DoD) for standby and moderate cycling use.

Sealed and maintenance-free

VRLA AGM construction with low self-discharge (under 2% per month at 20 C) - no watering, no routine maintenance.

Frequently asked questions

Why would I use a telecom battery on a boat or RV?

The front-access terminals and tall, narrow case fit spaces a standard wide battery can't - and you can reach the terminals without pulling the battery out. They're a popular choice when locker space is tight.

Does it need a BMS?

No. It's a drop-in lead-acid battery - just charge it with the correct AGM profile.

Can it handle high starting loads?

Yes. Low internal resistance and high cold-cranking and short-circuit current make it well suited to engine starting and large inverter surge loads.

What warranty does it come with?

A 2-year worldwide limited warranty from Victron Energy. Blue Marine handles the warranty claim process for you. Email support@bluemarine.com.
