Powershot A590
Canon PowerShot A590?

I have a Canon PowerShot A590 em regularly to replace batteries marks what should I buy to last longer and do I need a battery charge if so what kind would be great?

I have the same camera. The camera does not lose the batteries daily, which I just got the Energizer rechargables. These batteries are impressive. Last throughout the day, even twice. I can take lots of pictures and all / almost all with flash. I think it lasted about 150 shots … here is a link so you can see …. http://www.energizer.com/products/hightech-batteries/rechargeables/Pages/rechargeable-battery-charger.aspx
