Vapex “instant” Batteries are the latest in rechargeable battery technology from one of the very few  companies in the world capable of producing this latest innovation in rechargeable battery technology.

It is well known that high quality NiMH rechargeable batteries outperform disposable ones (including even the very best alkaline batteries) in power hungry gadgets such as digital cameras, but there were 2 areas where they had problems..

  1. They had to be charged before first use.
  2. Once charged they would run down without even being put in anything, typically losing around 25% of the stored energy per month. Not really a problem when you are charging them frequently, but for low power or occasional uses this could become inconvenient.

Vapex “Instant” batteries utilise a new technology which solves these problems.The batteries are supplied charged, so just use them straight after purchase
The batteries discharge at a much slower rate than conventional NiMH batteries, so even a year after being charged there is still most of the initial charge available. So you get all the benefits of traditional NiMH rechargeable batteries, without the drawbacks - and you can still use a standard NiMH charger to charge them up again maximum charge current 2500mA)

Below are our actual test results of the Vapex Instant 2500mAh batteries against the Panasonic Eneloop PRO 2500mAh batteries.
