ZOLL Medical Corp. is asking customers whose AED Plus devices have serial numbers with the last six digits below 200000 to perform a software update and submit confirmation to the Chelmsford, MA-based company.
According to a press release, ZOLL determined that some batteries do not work properly when used with defibrillators made before Feb. 12, 2009. The previous software did not adequately detect defective batteries, which could result in the machine failing to deliver a shock.
