Description

The Energizer Max Plus 9V is a single-cell alkaline battery using the PP3 (6LR61) format, delivering 9V nominal voltage for devices that require higher voltage in a compact form factor. The battery measures 48.5mm height x 26.5mm width x 17.5mm depth and weighs 30g, fitting standard 9V battery compartments in smoke alarms, remote controls, wireless microphones, guitar pedals and multimeters.

Designed for medium-drain devices rather than high-current applications, the Max Plus 9V provides reliable power for equipment that draws intermittent or moderate current over extended periods. Smoke alarms typically run 12-18 months on a single Max Plus 9V depending on test frequency, while wireless microphone systems and active guitar pedals see 8-12 hours of active use. The battery carries a 5-year shelf life when stored at room temperature, making it suitable for emergency backup applications.

The leak-resistant construction uses a crimped seal between the positive and negative terminals to reduce the risk of electrolyte leakage that can damage device contacts and circuit boards. Energizer rates the Max Plus range as providing up to 50% longer runtime than their standard Max alkaline batteries in compatible devices, achieved through improved internal chemistry and lower internal resistance. The battery is mercury-free and cadmium-free, meeting EU Battery Directive requirements.

Frequently Asked

How long does it last in a smoke alarm?

In a typical residential smoke alarm that self-tests weekly, a Max Plus 9V provides 12-18 months of operation. Older alarms or those in cold environments may see reduced runtime. The alarm's low-battery warning typically sounds when 10-15% capacity remains.

Is it rechargeable?

No. The Max Plus 9V is a single-use alkaline battery and cannot be recharged. Attempting to recharge alkaline batteries can cause leakage, overheating or rupture. For rechargeable 9V power, see NiMH rechargeable 9V batteries.

What's the difference between Max and Max Plus?

Energizer rates the Max Plus range as providing up to 50% longer runtime than standard Max batteries in compatible medium-drain devices. The Max Plus uses improved internal chemistry and lower internal resistance to deliver extended capacity.

Can it be used in guitar pedals?

Yes. The Max Plus 9V suits analogue and digital guitar pedals, providing 8-12 hours of active use depending on the pedal's current draw. High-gain distortion and digital modulation pedals draw more current and will deplete the battery faster than simple overdrive or buffer pedals.
