TAB 5GVRLA100 AGM 12V 100Ah Battery – UPS, Solar Backup and Generator Sets

TAB 5GVRLA100: a 100Ah AGM battery for power backup

The 5GVRLA100 (12V 100Ah), part of the TAB 5GVRLA range, is built with pure AGM technology and high-purity raw materials. It's a float-battery by design: built for installations that need an always-available power source with an immediate response to a power outage, rather than for daily deep-discharge cycling.

AGM technology: fast response, low maintenance

AGM (Absorbent Glass Mat) construction immobilizes the electrolyte in a microporous fiberglass mat, reducing internal resistance (4.9 mΩ on this unit) and allowing it to deliver high current spikes instantly — up to 1,000 A over 5 seconds and 2,500 A under short circuit. That fast response is what makes it the go-to technology for continuous float applications, such as UPS systems and generator starting.

Key strengths

• EUROBAT service-life classification — 10-year design life at 25°C.
• Very low self-discharge (≤2%/month), critical for equipment left unsupervised in standby for months.
• High gas recombination efficiency, minimizing electrolyte loss over the battery's full lifespan.
• Flexible mounting: vertical or horizontal, depending on available rack or cabinet space.
• Sealed VRLA construction: zero maintenance, zero leak risk.

Applications

UPS and EPS systems

Its main use: backup power for uninterruptible power supply systems and emergency power systems, where the battery works in constant float mode and must respond reliably during a power failure.

Generator starting and backup

Its high discharge current makes it just as suitable for generator starting as for its role as a reserve bank.

Backup in solar panel installations

In photovoltaic systems with a hybrid inverter-charger (grid + solar), this AGM battery can be used as a backup or float-reinforcement bank. That said, if your installation will put the battery through daily deep-discharge cycles (off-grid self-consumption), we recommend the TAB 5GVRLA250, built with hybrid AGM-GEL technology specifically for that use case.

Telecommunications and emergency power

Telecom cabinets, alarm control panels, and emergency lighting that need a stable, long-lasting power source with no periodic maintenance.

Technical data

Frequently asked questions

Is it suitable for a self-consumption solar installation?

It can be used as a backup or reinforcement battery in systems with a hybrid inverter-charger, but being AGM (not hybrid AGM-GEL) it has lower tolerance to daily deep-discharge cycling than the TAB 5GVRLA250. For self-consumption with heavy daily cycling, we recommend that hybrid version.

Is it AGM or GEL?

It's a 100% AGM battery, distinct from the hybrid AGM-GEL models in the same TAB 5GVRLA range.

What maintenance does it need?

None: it's a sealed VRLA battery, with no water top-ups or electrolyte level checks required.

Can it be installed horizontally?

Yes, it supports both vertical and horizontal installation, making it easier to mount in racks and technical cabinets.
