Durable high performance rechargeable batteries are becoming increasingly more and more needed all across the world. Thousands of new power hungry devices come out every single year. You probably already own many devices that would simply be unrealistic without rechargeable batteries. Cell phones, laptops, MP3 players, digital cameras and many many other devices just wouldn't be realistic without rechargeable batteries. Imagine having to pop in 20 AA batteries every time you wanted to unplug your laptop. Lanterns are no exception really, they eat tons of batteries(as any person with a battery powered lantern can tell you) and luckily some of them have come into the twenty first century and now use rechargeable lantern batteries.
This worries many people because they see a higher cost and naturally want to go for the cheaper one. What they don't realise is that the small up charge will pay for itself very quickly. Rechargeable batteries are simply more cost efficient, they pay for themselves because you only have to buy a new one every 500-1000 charges.
Older rechargeable batteries had many drawbacks though. These batteries had one big problem. They lost their charge if you left them laying around for too long without using them. Some types actually completely lost thecost efficientir charge in as little as two weeks.
This was never really a problem for some devices. Your laptop and cell phone are both used constantly for example, but other devices only come out every once in a while. I always had this problem with my old digital camera. I didn't use it very often so every single time I went for it was nearly dead. For most people, their lantern will be the same way. In between camping trips they basically go unused. The biggest problem I always found however, is that when you most needed it was emergencies such as the power going out. If it wasn't holding its charge then you were screwed.
Lucky for us, technology caught up to our needs. A modern rechargeable lantern battery will hold a charge much longer. Radical improvement to the technology, specifically the power cell, has made the rechargeable lantern batteries capable of holding as much as 80% of their charge for an entire year. I think this should do just find for just about anyone.
