Does rechargable battery power get lesser after years of usage?

[Paul_Yeo]

I find that my flash unit using sony 2100 rechargeable AA battery , take longer to refresh the power now compared to last year.

Last time I can shoot continuously, now, the 3rd or 4th shot, the flash will not fire and the pic taken has no flash.

use my battery intensively for nearly 2 years.

Is it normal?
