Problem is the local shop's likely closed 'cos you've pulled another all nighter, or you just plain can't be bothered moving from your comfortable surroundings. What do you do - stop having fun? We didn’t think so.

Instead you pop out your alkalines, zap ‘em in this re-charging device, wait for the green light and you’re good to go for another marathon session of play. Yes, that’s right - this gadget charges standard alkaline batteries. We didn’t believe it either, but we’ve tried it and it works.

Apart from saving you wads of cash (allowing you to shop online even more), re-using your old batteries is great for the environment. Standard alkalines can be recharged up to 15 times – that’s a lot less toxic chemicals and heavy metals polluting our landfills and waterways!

The ReZAP 5-in-1 Battery Charger ain't no one hit wonder - Titanium, RAM (Rechargeable Alkaline Manganese), NiCd (Nickel Cadmium) and NiMH (Nickel Metal Hydride) batteries can all be given a new lease on life. The ReZAP supports a whole raft of battery sizes, including your large 6V lantern batteries - it even manages to cram a battery tester right on to its front panel.

The best thing is this great product, being Australian designed and engineered, is solidly built, completely safe and a doddle to use. With automatic detection of both battery type and size you can forget about having to remember complex switch settings – basic instructions are right on the unit, ready to solve your next battery dilemma.

Reckon we're pulling your leg about this magic battery charging device? Don't take our word for it - here's an independent review (pdf).

The ReZAP battery charger does not include batteries, but comes with a two year manufacturer's warranty upon registration. AAAA, AAA, AA, C, D, N, 9V, 6V lantern and prismatic (rectangular and flat in shape) battery sizes are all accepted by this re-charger.

9V and 6V lantern battery life can be extended up to 5 times, Alkaline and Titanium up to 15 times, RAM up to 25 times and NiCd and NiMH up to hundreds of times. Cycle life depends strongly on factors such as brand, quality, condition as well as rate of discharge, cut-off voltage and depth of discharge of batteries. Do not be surprised to find that some top brand alkaline cells yield fewer cycle lives than less well known brands. Trying different battery qualities and brands yourself is the best way of determining which batteries best suit your applications.

Please note: The ReZAP Battery Doctor includes detailed operating instructions that must be read and understood before use. It is not intended for use by young children. Although the ReZAP is a multi-chemistry battery charger, it is not designed for Carbon Zinc (such as those labelled HEAVY DUTY or GENERAL PURPOSE) or Lithium (such as those used in cameras) batteries. The Use & Care Guide includes a table to assist with recognising and selecting the battery types for use with this battery charger.
