Hi all,
My neighbour has an MX5 (2003, 10,000 miles) and she doesn't use it very often. She killed the first battery so I got her to buy a new Absorbed Glass Mat battery back in January. The one we fitted was a Westco model. See:
Problem is she has been away for a lot of the summer and has come back to a completely discharged battery. We jump-started the car the other day and took it for a drive of a few miles but there was absoultely no life at all in the battery when we got back. I did recommend a trickle charger back in January...
We've been trying to charge it using an auto-charger designed for gel batteries that says it should charge it at around 800mA but after 72 hours of charge (with the battery still connected to the car) there is absolutely no life at all in it. I've now disconnected the battery from the car and am trying to charge it like that. Will this help? Or will the fact that the battery was completely dead flat and then we jump started the car and drove it for a bit have completely killed it?
Do others have experience of MX5s draining batteries quite quickly when not used for a long time.?
Thanks,
Tony
