Battery Charge Life

[ALE 111s]

Roughly what is the life of the charge on the battery fitted to S2 ? If unused for a week will it go flat ?

[Lotus Lewis]

No i wouldnt have thought so not if its kept in a dry garage

I left mine for 4 weeks without issue. Started first time.

Mine's been fine when I've been away for 3 weeks. I don't alarm the car though because it's in a locked garage - dunno if that makes a difference.

My previous, new Exige S struggled (but didn't actually fail) after 3 weeks, due to the immobiliser drain. My S1 (which still has its original battery) is now permanently on an Accumate battery conditioner - no worries.

After a week mine struggles to fire although touch wood hasn't failed. What's a battery conditioner ?

This is the one I have. Basically, keeps the battery fully charged when it is not in use.

Thanks, unfortunately I don't have an outside power source so will just have to drive it more often.

You can get solar ones, not used one myself but have been thinking of researching these... i think the trouble is finding one powerful enough!

I have one of these, was £20 from Maplin, works even in the shade of the car port, and means the alarm drain no longer slowly flattens the battery over time. Highly recommended.

Not much use though if it's underground parking... I also have the "no plug in garage" problem. I saw an add for this black and decker thing that, unlike the portable jump starters, actually charges the battery through the lighter socket - you just charge it up at home and then plug it in.

Although, I spent 10 mins trying to find a lighter socket in my elise 111R to no effect the other day. I could always read the manual I guess (the last refuse of the damned

Mine gets left on its lonesome in the garage for four week stretches (6 times a year) with no probs at all.

I saw this one http://www.maplin.co.uk/module.aspx?ModuleNo=11519... but in the FAQ's someone asks if it will charge their 50amp battery & the answer is no...??? does that mean it's fine to trickle charge / condition, but won't charge from flat?

is the one I have.

It's not for charging from flat. It does mean that the alarm and time passing don't run the battery down.

The solar route may be the way to go, I guess it's vunerable from next doors cat using it as a litter tray.

[cheekymonkey]

Think I'll get a solar & mount it in the back of the garage as there are a couple of sml windows, should keep things ticking over ok when it's not used much.

Just a warning to you all, that if your battery is low, it can put more load on the rather fragile alternator in the elise, and can result in it frying (according to the advice I got after killing mine).

[ALE 111s]

Can anyone confirm if the solar chargers work through glass ? I was hoping to plug into power socket and place solar panel on the dash.
