AI-generated summary
For £12.05 ex-VAT, the HP Poly Savi 8240/8245 battery looks like a sensible “keep the fleet running” buy—*if* you’re replacing failed spares for a deployment you already have. In real office life, headsets and their batteries are what slowly kill day-to-day productivity: call dropouts, weak standby, and managers complaining that “it doesn’t last.” This kind of replacement is typically cheaper than swapping whole devices and avoids the faff of retraining or dealing with compatibility issues.
That said, don’t buy it unless you’re sure it’s the right model for your exact Savi units. If you’ve got mixed handset generations or you’re unsure of compatibility, you can end up paying shipping to fix a problem you could’ve avoided. Also, at this price point, it’s not the kind of battery you’d expect to “upgrade” performance—just restore what you already had. Overall: good value as a spare for existing 8240/8245 users; a poor choice if you’re shopping for a general-purpose power bank or a cross-compatible headset battery.
