Can any one confirm that the roadster battery is the same as the one fitted to the mx, is it the same size & is it sealed? (11/99)
Yes, yes, and yes. The WestCo battery from Moss is a good (if slightly expensive) replacement, but nowhere near as expensive as buying one from Mazda ! (11/99)
I read somewhere that if you quote the following part number at your local Mazda dealer, it turns out to be for a gel-type battery as originally fitted. No idea of the price though. B61R-18-520C Might be worth a try. (11/99)
The original Roadster battery is a real one-off, specially made for the MX-5, and replacements weren't even available from Mazda as they could only make enough to fit new cars! Although 'maintenance free' it's not fully sealed, the vent cap has a hose which carries fumes out of the boot. Mazda produced an adaptor kit to fit a larger battery, and I've also seen an advert for a gel filled battery to replace the original. I've not delved into the boot to confirm this, but my manual says the standard battery is an S46A24L(S). (11/99)

How much is it and what's so good about it? I must admit I have a 40 quid vented lead-acid in ours! Seems to work fine and no sign of rust or anything. (11/99)

Erm - I think it was just under 90 quid, but the advantages are; It's teeny (anything to increase boot space :-) It's completely sealed, to the extent that it's the only car battery that can be sent through the post ! (and so needs no venting) Thinking about it though, a vented soggy battery for less than half the price does begin to make sense ! Heigh-ho; at the end of the day, anything was better than the original battery I had; I hate not being sure if my car will even turn over, let alone start in the mornings :-( (11/99)
The original (Panasonic) battery is still available, on special order only, for about #75. I know of 2 people who recently got this via local Mazda dealers (for imports).
