replacement batteries
 

got a 2001 voyager in the uk ,is there an alternative battery i can use instead of optima(red top) type battery 2.5 diesel 800 amp battery

Personally I didn't risk it. When my local motor factors showed me the equivilent 'normal battery' and it was twice the size.
I bought my Optima battery from 'griffin-batteries' on ebay. Lowest price I found and awsome service. (Next day delivery)
Good luck. (I'm in the UK too)

Have posted the last message, I'd read this thread and consider the modified battery tray route.

Lead-acid replacement for Red Top gel battery
 

Hi
Just bought a 2007 GV 2.8 Executive from a local main dealer. It's got an Exide Excel EB741 74AH 680A lead acid battery fitted. It's a perfect fit and seems fine. The R/top has high cranking power (800A) but low capacity (50AH) and give the alternator a hard time keeping it fully charged. I bought a new 2001 GV 2.5 CRD LIMITED and the battery didnt last 12 months.
Hope this helps. John.
