I have a 1998 Mk2 MX-5 that I have owned for 6 years. After 12 years of use the original Panasonic battery finally became too weak to continue and I decided to buy the WestCo battery as a replacement in May 2010. Frankly this battery has been a huge disappointment and it was clear from when it was only months old that it was not going to be reliable. I have followed the guidance notes to the letter and only used a trickle charger to charge in winter but the battery will not hold its charge. I have called MX5 Parts on two occasions to report the problems (logged my last call on 8/3/11 when the battery was not even 10 months old) but the only feedback is that these batteries are different and require to be charged for 4 to 7 days on trickle charge to maintain performance. This is not at all convenient and nor have I found it to be effective.
I have limped through 2 winters with this battery and I permanently keep jump leads in the boot as a security. If used merely for day trips, it's OK but leave it for 3 or 4 days without use and the battery will have lost charge to the point where it no longer has the power to turn the engine.
Despite the hype there is NO comparison between this battery and the original Panasonic. After a lot of frustration, I am resigned to giving up after just 2 years.
