Vivitar 替換電池組 LP-E8，適用於 Canon EOS Rebel T2i T3i T5i

This battery holds a charge noticeably longer than the generic I was using before, which saved me from swapping during a family event. The fit in my T3i is snug and secure, just like the original.

My camera died mid-shoot last weekend and this spare got me through another 400 shots without a hiccup. The battery fits snugly in my T3i and holds a charge about as long as the original did. Solid backup for the price.

Bought two of these as backups for a week-long trip and they held up fine across hundreds of shots. The lithium-ion cells match the original's capacity well enough that I never had to scramble for a charger mid-day.
