• Maintenance-free for its whole service life.
• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Long float life under permanent charge.

What the Long MSK500 is for

The Long MSK500 is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 33.50 kg.

Dimensions, polarity and mounting

It has external dimensions of 241 × 172 × 340 mm and weighs 33.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Long MSK500: MSK Series range and AGM technology

The MSK500 is part of the Long MSK Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

What Long does differently

Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Warranty and coverage

The Long MSK500 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

How to make it last longer

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.
