Rechargeable batteries are what’s "in" these days, not only because they are far more cost effective—they’re capable of accepting up to 1000 charge/discharge cycles-- than alkaline cells but also because alkalines shows operational inefficiency and short life when used with digicams. Our camera’s supplied rechargeable batteries need some taking care of also. They will not last to the factors of such deep discharges, over-charging and over-heating.
Have you ever experienced shooting an event wherein your batteries would just die on you? What you need to go with your batteries is a "smart" battery charger, one that diagnoses the condition of the battery, refreshes the cell and optimally recharges them--like those that a German company, Ansmann, have produced for our benefit. Majority of us, FPC members, are hobbyist and most of us probably only need a charger which can accommodate 4 pieces of AA or AAA batteries.
One of Ansmann’s charger that I recommend is the Digicam Power Set Traveller, consisting of the award-winning PowerLine 4 Traveller charger with 4 NiMH AA cells. This “Power Set Traveller” is an ultra-quick, microprocessor controlled, lightweight & compact charger.
It has been voted and given awards for its high and cost-efficient performance; these awards include: the Digital Photographer Buyer and User Best Buy; the Digital Photo Gold Award; the Photo-Industry Awards for Best Accessory; and, Highly Commended by Digibattery.co.uk.
Let me explain to you what this charger does. First off, the Digicam Power Set comes complete with four AA size 2400mah cells (also includes plug adaptors for UK, Euro, US and Australia), and an automatic supply voltage changeover. It is a microprocessor device that features individual cell control. When rechargeables are inserted, it (1) first makes a quick check on capacity, (2) auto-diagnoses the state of each cell, and then (3) uses Delta Peak control for each cell’s recharge. Delta Peak has to do with the control of input voltage and cell temperature, thus minimizing damage to the cell’s chemistry and structural integrity.
Here's the specification of the Digicam Power Set Traveller:
Plug in charger for 1-4 cells AA or AAA
