Could be that they tried and did add water through the fake caps (a no-no). This can destroy the gel contents. I would not think the charger had anything to do with it. The gel packs like to be continually charged with a battery tender and are more prone to (and most likely) failure was due to low voltage. Lead acid ones loose about 50% of capacity life if allowed to go below 80% or 10 volts for any length of time. But gels come back well up to about 60% or about 8 volts. After 6 volts they are both DOA>. Also, If continually charged and monitored the gells will outlast the l/a batts by 100 - 150%. There is no substitute for battery tenders except new batteries every year....more prevalent in lead batteries due to the electrolysis (the acid conductance on top between the terminals) which will take away about 2 volts per month. john ----- Original Message ----- From: 2HsandaHeritage@xxxxxxxxxxx To: "Chrysler 300 Club International" <Chrysler300@xxxxxxxxxxxxxxx> Sent: Monday, December 5, 2011 10:11:31 AM Subject: [Chrysler300] Mopar Battery Hi Group, I just lost my correct looking " Mopar gel battery" due to my painter trying to either jump start or charging it with a standard 40 amp charger. I am not sure that I want to replace it with another gel battery with the correct looking casing - $314 with shipping! I checked the new batteries at my local Chrysler dealer and they now just have a large Mopar sticker on the exposed side - No Thanks! Does anyone have any suggestions for a new battery source that looks at least somewhat correct? Doug Warrener Fair Oaks, CA 300H 62 Sport Conv.
