Know a battery is failing before it fails you.
A Battery Management System monitors voltage, current, temperature and state of health across an estate, and flags degradation before it causes an outage.
In a single-battery installation you find out a battery has failed during a power cut. Across fifty sites you find out from a customer complaint, a week later, after the third one. Monitoring changes failure from an event into a scheduled task — and a scheduled replacement costs a fraction of an emergency one.
Leasing rather than buying the system matters for the same reason it does elsewhere in our range: BMS hardware and software both date, and a purchased system is a depreciating asset you are stuck with. Under a lease, upgrades arrive during the term rather than requiring a new capital case.
Six things in one monthly cost.
Leasing agreement
A lease over a specified term, typically one to five years, spreading the cost of the system over time rather than requiring it upfront.
Customisable plans
Packages tailored to the number of battery systems, the monitoring features needed and the level of support required.
Installation & maintenance
Our team handles installation and ongoing maintenance, keeping the system operational and current throughout the term.
Upgrades & data insights
Software updates and hardware upgrades are included, along with real-time analytics that surface issues early and help optimise energy use.
Support & training
Technical support, staff training and proactive monitoring are bundled in, reducing the load on your in-house team.
Cost predictability
Predictable monthly costs with repairs and replacements typically covered, so a failure does not become an unbudgeted expense.
Which model fits your estate?
Three of our services overlap in the minds of buyers. The difference comes down to what is leased, what is owned and what is serviced.

- FAQs
Battery Assurance — frequently asked questions.
What is Battery Assurance?
Battery Assurance is a leased Battery Management System. Rather than buying BMS hardware outright, an organisation leases it over a term of one to five years, with installation, maintenance, software and hardware upgrades, staff training and proactive monitoring bundled into a predictable monthly cost.
What is a Battery Management System?
A BMS monitors the condition of a battery estate — voltage, current, temperature and state of health — and flags degradation before it causes an outage. In multi-site or multi-battery operations it is the difference between discovering a failure during a power cut and scheduling a replacement in advance.
How long are Battery Assurance lease terms?
Terms typically run from one to five years, which spreads the cost of the system over time rather than requiring it upfront. Packages are tailored to the number of battery systems, the monitoring features needed and the level of support required.
What is included in the lease?
Installation of the BMS, ongoing maintenance, software updates and hardware upgrades during the term, technical support, staff training, and proactive monitoring. Repairs and replacements are typically covered, which is what makes the monthly cost predictable.
How does Battery Assurance differ from Battery-as-a-Service?
Battery Assurance leases the monitoring and management system while you continue to own the batteries. Battery-as-a-Service means ReStore Life owns the batteries themselves. Assurance suits organisations with an existing estate they want managed properly; BaaS suits those who would rather not own the assets at all.
Does Battery Assurance work with existing batteries?
Yes. The system is designed to monitor and manage an estate you already own, which is the main reason organisations choose it over replacing hardware.
