So i finally gave up with buying replacement batteries and decided to go rechargable. While browsing the aisles i couldn't help but stop at this "cigar case" shaped device. For £14.99 i was sold. The charger came with four AA NiMH 2700 mAh batteries, a carcord and boasted to be able to recharge the batteries in just one hour.
The batteries included on full charge gave me about 6 hours screen display time on my digital camera so they have quite a long life compared to most. The charger itself can take Ni-MH Or Ni-CD barreries and can charge up to four AA or AAA batteries at a time. It also has a safety timer to make sure the batteries are not overcharged and so will not overheat. It runs on 100V-240V and can be used universally. There is an LED light on the case that let you know how long through the charge it is.
It doesn't lie when it says it charges in one hour as i found the lifespan after the charge was the same as first using the batteries. Although i am told that eventually rechargable batteries deteriorate in lifespan so may need to be replaced. But so far so good! Definately worth buying to save you money in the long term.
