My Profoto 7B battery does not hold much of a charge any more.
All the above links are dead now.
Can anyone recommend a replacement Life Battery?
Can I use my existing charger or do I need to get a new one?
To my knowledge, the Pro-7B was never rated for LiFe batteries, although they should work. More significant is market availability, particularly from third parties like Tenergy. You may be stuck with good ol' SLA in its boat-anchor glory.
I offer re-celling service on Profoto 7B 1200 lead acid batteries. $150. You ship me your cassette, I send you back a re-celled Cassette within 7 business days. I accept PayPal and bank checks.
