We started out two weeks ago with five in circulation (cochlear implant batteries). We're now down to 3, and we have four CIs in our house. I hate that Cochlear Implant batteries (at least ABs) are not more durable. For $100-$200, they should hold up better. I have a plastic bag filled with 6 broken batteries right now (all broken between September and now). That's close to $1,000 worth of batteries- ouch.
O.K. Done venting :)
