Hi all, need advice on Rechargeable Batt, I have been using Sanyo 2300 sparingly for the last few years for my 580EX flash. Of late, the battery seems to have lost it's "performance",I am not too sure if it's a problem with the batt or charger.
Advice needed: Can I use any batt charger for these batteries, I have recently bought a GP charger from Challenger. If I were to get a new rechargeable batts now? Which would be a good investment?
Thank you in advance.
