If you have been looking for a quick way to double your daily battery life on your BlackBerry 7 device (at least most of them) then this is the deal for you. The BlackBerry J Series Extra Battery Bundle which includes an extra battery and external charger is selling for a super low price on Amazon. This battery works for the BlackBerry Bold 9900/9930, Bold 9790, and Torch 9850/9860. It allows you to charge a second J-M1 original battery while also charging your BlackBerry phone using the Y cable.
Keep in mind this is the same charger cable plus battery bundle that RIM is selling for $79.99 and others are selling for over $50. Check out the (RIM ACC-38580-301) RIM BlackBerry J – Series Extra Battery Charger Bundle – Battery – Retail Packaging for $23.49 on Amazon (and shipped by Amazon) from SF Planet.
PS: If you need to hit $25 for free shipping just bundle the charger with another $1.50+ if you don’t have prime. Take a look at one of the older MicroUSB wall chargers ($3.85) or newer smaller ones ($5.28).
