I have the LP-E6 battery being manufactured in 2010. Recharge performance indicator shows one red square only, so according user manual I should consider buying a new one. However, I didn`t notice the battery has lower capacity in comparison with another one produced in 2012. Therefore I wonder what parameter camera evaluates for recharge performance. Isn`t it simple "planned obsolescence"?.
Dear Friend Mr. Millan
From the Staff : Canon Company= I have same problem many years ago, and I CALL CPS. ( Canon Professional Services )
Battery LP-E6 Performance: It’s a fact that rechargeable batteries have a finite number of charge-discharge-charge cycles they can go through, after which they can begin to lose their ability to hold a charge. While the LP-E6 should allow photographers hundreds of charge-discharge cycles, it’s useful for the working photographer to know whether a battery pack is nearing the end of its useful life after several years of use. The Battery Performance indicator does just that, with a 4-stage icon:
3 Green Squares: Battery is providing full performance each time it’s charged
2 Green Squares: Battery still producing good power each time charged, but not to the level of a brand-new LP-E6 battery pack
1 Green Square: Battery is nearing end of its useful life; full recharge will not deliver performance matching a new LP-E6 battery
1 Red Square: Battery has reached the end of its useful life, and should be discarded and replaced with a new LP-E6 battery pack. Recharging or re-conditioning will not enhance its performance.
