Our verdict
The Dura16 is a lot of usable storage for the money: 14.4kWh of a 16kWh pack, at 6.6kW, with an 8,000-cycle rating that comfortably outlasts the 10-year warranty on paper. The familiar brand is licensed: it's built and warranty-supported by Puredrive Energy in Gloucestershire, which is worth knowing given how much a battery warranty depends on the company still being there. The catch is tie-in: it's sold only alongside a Duracell inverter, so it suits a new install rather than a retrofit onto an existing hybrid.
Good
- 14.4kWh usable at a competitive price
- 8,000-cycle LFP rating
- Scales to 12 units in parallel
Watch out
- Only sold with a Duracell inverter
- No whole-home backup
- Brand is licensed, not Duracell-built
Will it pay for itself?
9.8 years to pay back a £3,348 Duracell Dura16 from £342 a year of off-peak savings. That's inside the 10-year warranty.
