Depreciation on leased assets
Buying batteries ties up capital that could be working elsewhere.
BaaS is offered to bulk battery users who want to deploy their capital productively while meeting the operational need for dependable energy storage on an operating-expense basis.
The additional advantage of claiming depreciation on leased assets under Indian Accounting Standard 116 makes BaaS a uniquely viable option for finance and operations leaders alike. It is one of the few arrangements where the operational case and the accounting case point the same way.
There is a second effect that rarely appears in the pitch: under BaaS, the incentive to keep a battery alive sits with us rather than with you. A hardware vendor makes money when a battery is replaced. A subscription provider makes money when it is not — which is why our rejuvenation capability and this commercial model reinforce each other.
Five reasons finance teams choose BaaS.
Cost efficiency
Eliminates the capital investment of purchasing new batteries, freeing funds for other productive uses.
OPEX flexibility
An operating-expenditure model improves cash-flow management and lets finance teams expense storage rather than capitalise it.
Depreciation benefits
Customers can claim depreciation on leased assets under Indian Accounting Standard 116, delivering a tax benefit alongside the cash-flow advantage.
Scalability
Increase battery capacity as the operation grows, without a large upfront commitment each time.
Remote monitoring
Real-time monitoring of every battery in the estate, so lifespan, uptime and performance are managed continuously rather than reactively.
BaaS, AMC or outright purchase?
The three models differ less in what gets done to the batteries than in who owns them and who carries the risk.
| Outright purchase | AMC | BaaS | |
|---|---|---|---|
| Who owns the batteries | You | You | ReStore Life |
| Upfront cost | Full CAPEX | CAPEX already sunk | None |
| Accounting treatment | Capitalised asset | Service expense | Operating expense |
| Who carries failure risk | You | Shared | ReStore Life |
| Scaling capacity | New purchase each time | New purchase each time | Adjust the subscription |
Accounting treatment depends on how a specific contract is structured — finance teams should confirm with their auditors rather than relying on a general description.

- FAQs
BaaS — frequently asked questions.
What is Battery-as-a-Service?
Battery-as-a-Service (BaaS) is a subscription model for energy storage. Instead of buying batteries, an organisation pays a recurring fee and ReStore Life supplies, monitors, maintains and replaces the units. Ownership and performance risk stay with the provider; the customer pays for uptime.
How does BaaS differ from an AMC?
An AMC covers maintenance of batteries you already own — servicing, revival and spare stock, with the asset on your balance sheet. Under BaaS you do not own the batteries at all. The distinction is financial as much as operational: AMC is a service contract on owned assets, BaaS converts the asset itself into an operating expense.
What are the accounting benefits of BaaS in India?
Under Indian Accounting Standard 116, customers can claim depreciation on leased assets, which delivers a tax benefit alongside the cash-flow advantage of moving from capital to operating expenditure. Finance teams should confirm treatment with their auditors, as it depends on how the specific contract is structured.
Who is BaaS suitable for?
Bulk battery users — telecom tower operators, data centres, large solar installations, industrial sites and fleet operators — where storage is business-critical and the replacement cycle ties up meaningful capital. It suits organisations that would rather deploy that capital elsewhere.
Can BaaS capacity be increased later?
Yes. Capacity scales with demand without a large upfront commitment, which is one of the main reasons growing operations choose the model over outright purchase.
Are batteries monitored under BaaS?
Yes. Every unit is monitored in real time, so state of health is tracked continuously and intervention happens before failure rather than after an outage.
