Description

The JCB Ultra is a 9V PP3 6LR61 alkaline battery delivering up to ten times the power output of standard zinc-carbon 9V cells. The ultra-alkaline chemistry maintains voltage stability under sustained high-drain loads, making it suitable for smoke alarms, wireless microphones, guitar effects pedals, digital multimeters and active instrument preamps that draw continuous current.

Designed for devices that remain powered continuously or cycle frequently between standby and active states, the battery resists voltage sag better than zinc alternatives when driving circuits that draw 50-150mA at peak. Smoke alarms benefit from the extended service life between replacements, reducing the frequency of low-battery alerts. Wireless microphone transmitters and instrument preamps maintain output level consistency over the battery's discharge cycle, avoiding the drop-off in signal strength that occurs as cheaper cells deplete.

The battery measures 48mm height x 26mm width x 17mm depth in the standard PP3 form factor, fitting any device with a 9V snap connector. The blister pack protects the terminals from shorting during storage and the alkaline chemistry has a shelf life of several years when stored at room temperature. JCB rates this as their most powerful 9V offering, positioned above their standard alkaline range for applications where replacing batteries is inconvenient or where device performance must remain consistent across the full discharge curve.

Frequently Asked

How long does this battery last in a smoke alarm?

Service life depends on the smoke alarm model and how often it self-tests. Most smoke alarms drawing 50-80μA in standby with monthly self-tests will run 12-18 months on a JCB Ultra 9V before requiring replacement. High-sensitivity photoelectric models with LED indicators may use the battery faster.

Can this be used in guitar effects pedals?

Yes. Guitar pedals with analogue circuits typically draw 5-25mA continuously when active, which sits within the high-drain performance range of the JCB Ultra alkaline chemistry. Digital pedals with DSP chips may draw more current and deplete the battery faster.

What's the voltage when new?

Fresh alkaline 9V cells measure approximately 9.3-9.6V off the charger. Voltage drops to around 9V under load and declines gradually to 6-7V as the cell depletes. Most devices stop functioning reliably below 7V.

Is this rechargeable?

No. This is a single-use alkaline cell. Attempting to recharge alkaline batteries can cause leakage or rupture. For rechargeable 9V power, use NiMH or lithium-ion rechargeable PP3 cells rated for multiple charge cycles.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund. Customers pay return shipping. Made-to-order, special-order and clearance items cannot be returned. See full returns policy.
