NFE 7700 Batteries: What You Need to Know
The National Flooring Equipment 7700 Ride-On Floor Scraper uses a powerful AGM battery system designed to keep the machine working without a trailing power lead. Explore National Flooring Equipment in Australia.
From everyday charging to battery removal and eventual replacement, here are the key things to know about NFE 7700 batteries.
7700 Battery Basics
The 7700 is powered by 12 AGM (Absorbed Glass Mat) batteries, each rated at 200Ah.
At a glance:
- 12 × 200Ah AGM batteries
- Approximately 8 to 12 hours of operation
- Sealed, maintenance-free design
- No trailing power lead while operating
- Batteries can be removed from the machine
- Batteries should be replaced as a complete set when replacement is required
Actual operating time will vary depending on battery condition, charge and how the machine is being used.
Why Remove the Batteries from a 7700?
Battery removal isn't only relevant when the batteries need replacing.
There may be times when the batteries need to be removed for servicing, transport or site access requirements.
One consideration is elevator access. When taking a ride-on scraper into a multi-storey building, the total weight of the equipment needs to be considered against the elevator's rated capacity.
Removing the batteries reduces the weight of the machine itself and allows the batteries to be handled separately where appropriate.
Before transporting the 7700 in an elevator, always check the elevator's rated capacity, dimensions, machine configuration and site requirements. Removing the batteries does not automatically make an elevator suitable for transporting the machine.
How to Remove the NFE 7700 Batteries
Battery removal involves the machine's electrical system. Follow the applicable NFE instructions and ensure the person completing the work has the appropriate training.

What Are AGM Batteries?
AGM stands for Absorbed Glass Mat.
Unlike traditional flooded lead-acid batteries, AGM batteries are sealed and don't require routine water top-ups.
For an operator, this means less routine battery maintenance while still providing the power required for demanding floor removal.
Charging the NFE 7700
You don't need to completely flatten the batteries before putting the 7700 back on charge.
Avoiding excessive discharge and maintaining good charging habits can help protect battery performance and service life.
A simple rule is to not wait until the batteries are completely flat before thinking about charging.
Operators should also pay attention to changes in charging behaviour or runtime. If the machine suddenly isn't holding charge as expected, the batteries and charging system may need to be checked.

When Do 7700 Batteries Need Replacing?
There is no single replacement age for every set of NFE 7700 batteries.
Battery life depends on usage, charging habits, storage and operating conditions. Rather than replacing the batteries after a set number of years, pay attention to how the battery system is performing.
Signs that may require further investigation include:
- Noticeably shorter operating time
- Difficulty reaching or maintaining a full charge
- Changes in machine performance
- Unusual charging behaviour
- Battery or charging system faults
A reduction in runtime doesn't automatically mean the batteries need replacing. The battery bank and charging system should be properly checked first.
Replacing the NFE 7700 Batteries
Removing the batteries and replacing the batteries are two different things.
If the existing batteries are removed for access or servicing, they may be reinstalled.
When the battery bank reaches the end of its useful service life, NFE specifies that all 12 batteries should be replaced together rather than adding a new battery to an ageing set.
Using the correct battery specification is also important to maintain compatibility with the 7700's electrical and charging system.
