Help Regarding Battery Chargers
There are two main types of battery charger...
A timed battery charger and an intelligent battery charger. A timed battery charger will tend to charge rechargeable
batteries for a fixed length of time, after which the battery charger may switch to trickle charge or simply switch off. These battery
chargers are fine for batteries of a certain capacity. Say your battery charger takes 5 hours to fully charge 1700mAh AA batteries.
Perhaps these batteries came with the battery charger. All will be fine and your batteries will reach their full charge.
However, if you put higher capacity batteries in the same battery charger, it will charge for 5 hours at the same rate and your
higher capacity batteries will only ever be partially charged (to about 1700mAh).
Ok, so how about I charge the higher capacity rechargeable batteries again before use, using the same battery charger?
You could do this of course as this will give the batteries a double dose. But how would you feel if, on a drinking binge, your
capacity was say, 8 glasses of wine, and you were forced to take two lots of 5? You get the jist?
The charger will spend another 5 hours charging the batteries, but of course you risk damaging the batteries
by overcharging them. This will shorten their life. Quite an apt analogy perhaps?
We get many customers who purchase the new high capacity Uniross 2500mAh NiMH AA batteries and find that the performance of these batteries
is not much better than the 1700mAh batteries they were replacing. In most cases this is because the battery charger being used
is a timed battery charger. The best solution is to use an intelligent battery charger.
What is an intelligent battery charger?
An intelligent battery charger is just that, cleverer than a timed battery charger. It is often microprocessor controlled and charges the rechargeable
batteries until their full capacity is reached. Once they are fully charged, the battery charger stops charging, preventing your batteries
from being "cooked" which prolongs their life.
Can I charge NiMH rechargeable batteries in my existing NiCd battery charger?
Sorry, no. Well you can, but the battery life will be severely affected by this treatment. Some battery chargers allow the charging of both NiCd batteries and NiMH batteries.
Some battery chargers auto sense the battery type (like the Ansmann Energy 4 Traveller battery
charger) and some require a switch to be used to select the battery type.
The Camlink Z1 battery charger is ideal for charging Lithium-Ion batteries for digital cameras. If your
digital camera uses regular AA rechargeable batteries, the Ansmann budget charger EC-800 would be a
good choice for a low cost intelligent charger.

DT - Desk top chargers are supplied with a mains lead and plug. These chargers need to be placed on a flat surface to operate.
3. Batteries Included:
PI - Plug In chargers come with a plug integral to the charger and operate directly pluged into the socket.
4. Worldwide/In Car Use:
- Indicates that the charger is supplied with a set of 4 AA-sized rechargeable batteries. To see which type of AA batteries are included
click the product name to go to the product details.
- Indicates that the charger is supplied without batteries. Batteries can be purchased separately from our rechargeable battery
WW - Indicates that the charger can be used on mains power supplied in all countries. (110-120V and 220-230V, 50-60Hz).
5. Charging Speed:
IC - Indicates that the charger is supplied with a power lead that can be used to power the charger from a standard car cigarette lighter.
Fast - Fast chargers will charge 4 x 2100mAh batteries in . Fast chargers are useful if you are likely to use a lot of battery power in a short time.
Quick - Quick chargers will charge 4 x 2100mAh batteries in . Quick chargers are useful where batteries can be left for several hours to charge.

No - If not available the charger can only charge one type of battery at a time.
Automatic - This feature means that the charger will check each battery when it is put in the charger and determine if the battery needs to be
refreshed before charging in order to acheive its maximum capacity. This is useful when recharging older or frequently used batteries.
Manual - This means that the charger can run a refresh process on the batteries, but this is manually selected by the user.
No - If not available the charger will not refresh the batteries before charging.
