Seems my big old Bosch battery has suddenly run out of puff. I'm thinking of a lighter alternative to keep on with the weight savings project - so whose running a Varley Red Top 25 or alternative in something that's not a race car? My car's running a chipped 2.5 16v with lighter weight flywheel & clutch - no AC just PS. |

Running an Odyssey 925 for 3 years without issue. In fact I wish I went smaller to save more weight. Car can sit for many weeks and starts on the button. Never drained on its own accord. |

Thanks guys. I'll look into the Powervamp range. I recall seeing them somewhere. That Odyssey 925 is virtually 12kgs - the Varley 25 is only 7 but 20Ah and 230CCA - is the difference worth the risk of not firing up the 2.5? |

Don't waste your money, so-called 'motorsport' batteries are just jazzed up AGM leisure batteries. I run a Lucas AGM golf cart battery on my 951 and it works a treat. You'll need a proper digital charger as any equipment will drain it in a week or so if parked up, but the same goes for an Odessey or Varley. The best bit? The only cost around £35. I drilled and cut the posts off an old battery and bolted them on to the new battery to retain my original cable terminals. This is what I have, it's very light!! https://www.tayna.co.uk/Lucas-Golf-Batt ... P7938.html |

If the wiring is like my Escort there will be no drain at all if the stereo etc. is off. A handy thing to remember about the golf cart battery  .How quickly do your cars start up with them? I know a friend's MGB on a 123 distributor was very difficult to start as the voltage drop below 10 when cranking, enough for the distributor to no longer work. It would turn over just about. |

No difference to the mahoosive lead acid battery it replaced. If he's having an issue starting it's probably an earth fault, not the battery. That is unless it's a high compression engine perhaps? |

To be fair I think it may have been running more compression. That and the starter motor predates geared items ; they had a direct drive starter motor on them. |
