For most 7s I'd suggest:

  1. Consider the Great Lithium Question... 
  2. ... and if you're not ready to jump fit a Powervamp Clubsport. Current model seems to be the Clubsport NP. NB You might need a different size box from what you currently have (and they sell one) and terminal adaptors.

But mine lives on a conditioning charger. Is that a possibility for you, and if not how long would be long enough? And do you have a battery master switch and do you suspect high residual current when it's not being used?

With the demise of the Powervamp PVR22 last year the replacement recommended by PV is the PC680, this is a superior battery and therefore a bit more expensive at £98. On the plus side it fits the same cage as the outgoing PVR22. The other change is the terminal size which increases from M6 to M8 so you have to get your Dremmel out!

The PC680 has a 2 year warranty and will hold its charge for 24months which is handy for some Caterham owners.

For those who live in a climate that sometimes requires quite cold starts (below freezing), I can recommend this battery: Yuasa AGM GYZ32HL battery. At 500 CCA and 32Ah capacity, it significantly outperforms the Banner battery, which I had taken to carrying an additional booster pack with in spring and autumn for reliable starts. It also has a reputation for robustness and long life from Harley owners (commonly used as a motorcycle and recreational vehicle starting battery). I paid the equivalent of £145 for it delivered. It is a tight fit in the Banner battery tray depth wise, but is a similar height and a bit narrower, I decided to make myself an exact fit tray and reused the top clamp used on the Banner battery.

The Powervamp Clubsport NP costs £50. What do you see as the advantages of the PC680?

Thanks

My recommended battery for most purposes in most 7s (if you don't want a lithium) is now:

  • The Powervamp PC680.
  • £84.47 plus VAT plus £10 shipping by Fedex,
  • From Powervamp on 01934 643000.

Thanks Jonathan. Thinking of putting new battery on for next year my problem is when driving I put on headlights  but always   Forget to switch of so if leave car for  to long  come back  to flat battery  I always carry set of jump leads and tow rope   When car in garage plug in trickle charge unit       But before I go away next year.     Am going to buy  one of those.  Small jump starters.   As on previous site    Forgot what they are called around £100.   But think worth it.  It also may help some one else on our travels

Had my 680 on the car for 6-7 years.

Never trickle charged, getting drained to zero a couple of times and 5 months of winter stored below or near zero 'c.

It still cranks the VX no issues, I would buy another if this one decides to pack it in.

Just noticed that there are two things missing from this thread that should be here as it evolves towards wikihood.

Migrating from the factory configuration to a Powervamp battery might need some or all of the following:

  1. Longer cables.
  2. Different ends on the cables.
  3. Modifications to the cage. Or a pretty new Powervamp cage.

NB The desirability of insulating hoods on battery terminals.
