High capacity but generate a lot of heat
on 5 September 2017
I use a lot of rechargeables in photographic equipment, speedlites, triggers etc and mainly Eneloops. I bought these to test after seeing a well known photographer promote them and the fact I use a Maha charger.
I tested these with a speedlite and they did give more flashes than the Eneloops but they are 2700mAh where the Eneloops are 2500mAh. The reason I am actually giving these 3 stars is the heat generated under stress testing i.e continuously firing the flash until the overheat warning comes on. These only lasted 50 pops before I had to switch the speedlite off and remove the batteries, leaving the battery hatch open to cool the speedlite. The batteries were nearly too hot to handle and had to be placed on a concrete floor too cool. They did go on to give more overall pops than the Eneloops but the Eneloops did not generate the same amount of heat and so I got more pops before overheat protection kicked in.
These are let down by the heat issue and while they may give more overall pops it takes them longer to get there as the Eneloops require less time to cool and can hit around 200 pops a minute or so quicker than the Maha's.
If you want to use these for an application where they will not be put under this kind of stress then they should be fine.
