flashgun batteries? which ones?
-
hi all, ive been using a flashgun alot more recently and have noticed how they like to chew up batteries when getting used. now i dont have a battery pack for it just yet, but i will be getting one. but until then and even when i do get it ill need some decent batteries for it. and to save some money ill be looking for good rechargeable ones (AA).
so my question is, what are the best (longest lasting) batteries (rechargeable AA) to get??
thank you
regards
MickSanyo Eneloop. The best by miles and arguably one of the cheaper packs too!
The Eneloops are good (though I did get a duff set) and have since tried
7dayshop’s own brand, which are the same as Eneloops ie no memory, holds
the charge etc. a fraction of the price but so far have only charged them once
in two months with fairly regular use in a SB600 flash.I’ve been using Contour high capacity NiMH rechargable batteries (2750 mAh) in both my 580EXII’s and find them good. They definitely last as long as normal disposable Duracell batteries & have a fast recycling time too. They shouldn’t be mixed with disposable batteries. Available from Argos.
nice one, thanks for the replies.
so am i right in thinking the higher the mAh value the longer they will last and shorten the recycle time??
Basically speaking, yes.
NiMH Batteries Have the Following Advantages :•Drive better performance with high-drain electronic devices
•Large capacity for longer device operation. NiMH rechargeable batteries can last 2-4 times longer than alkaline throwaway batteries or NiCd rechargeable batteries
•Long battery life, can be charged/discharged up to 500-1,000 cycles.
•Extremely low battery cost per unit of device operation (such as every photo taken or every hour CD is played), providing very low cost of consumables for your electronics.
•Stable performance due to flat discharge curve. NiMH battery will remain in high voltage during 80% of the usage cycle. •No memory effect for easy charging and usageIt’s possible, but not recommended, to use a Nicd charger to charge NiMH batteries. A smart NiMH charger is designed to cut off power or go to trickle charge when the batteries are fully charged and is the best option.
Nicd chargers use a timed circuit ( 8hrs, 16hrs etc) when charging batteries. This can lead to overcharging partially used batteries, as the charging will continue to charge even after the battery is fully charged. This leads to overheating & battery damage.
NiMH chargers are a little more expensive, but will avoid overcharging the batteries & go to trickle charge (or switch off) once the battery is fully charged. They are still fairly cheap to buy & are also made & supplied by the battery manufacturers.
Eneloops are good – but their main (only ?) advantage is that (unlike standard NiMH batteries) they lose their charge very slowly. So you can charge them up, and still use them weeks later. Disadvantages are lower capacity and higher cost.
If I was getting just one set of batteries, I would probably get Eneloops. However, for multiple sets, I would get mainly standard NiMHs for day-to-day use and 1 Eneloop set as a backup (this is basically what I have – except I have multiples of everything).
I’ve found the 7DayShop own-brand rechargeables to be fairly reliable and good value. I only use a good quality charger for them (Maha).
cool all the info will be stored and used to hunt down the best price on all, so far 7dayshop are ahead on price for both their own brand and the eneloops, but the chargers arent in a pack on their site and need to be purchased separately…. so thats another hunt for the right one to go with the right battery
