Dragonlasers Spartan 1W Tenergy RCR123A 3.0V 900mAh?

[viro]

has anyone tested these? - Tenergy RCR123A 3.0V 900mAh Rechargeable Li-Ion Battery

i actually have them: Tenergy LiFePO4 RCR123A 3.0V (3.2V) 750mAh Rechargeable Battery


so basically the 900mah ones have the same output but last longer?
