NB-1L
NB-3L
NB-4L
NB-5L
NB-6L
NB-8L
NB-11L

A:AnswerIt will not as those cameras take bigger camcorder like batteries and this charger is more for smaller flat camera batteries such as point and shoot cameras.
A:AnswerHello, no, this would not work with your Canon Rebel T1i, however, the charger that would work for this is the RF-DSLR-500C. This compatible charger is available at BestBuy.com by simply typing in the search box the item number "RF-DSLR-500C".
A:AnswerNo, it will not work. However, you can purchase the re-fuel charger "RF-DSLR-500C" from the BestBuy website as this is the correct charger for your battery.
