<p>John,</p>
<p>Do you use a battery maintainer? They can help (but AGMs should
have one tuned for them). Have you had your starter rebuilt? The
field coils, in particular, can degrade and reduce the starter
output considerably. Solenoids degrade over time, too.<br>
</p>
<p>It doesn't get that cold where you, and I used to, live; you
shouldn't have that much trouble starting your Healey in the
winter, even if it's sat for a couple months. Mine would take
10-15 seconds of cranking in the winter after sitting to start, as
opposed to maybe 5 seconds in warmer months.</p>
<p>Switching to a lower-viscosity oil, for the winter at least,
might help some too. I use 20W-50 year-round. My experience with
the 'boosters'--exactly one--is that they might help a marginal
starter/battery over the top, but will not cold start a completely
dead battery, and least not on a big 6- or 8-cyl engine.<br>

<p class="MsoNormal"><span style="color:#1F497D">When starting
it in the winter, the battery starts to give out, but not
completely (yet) before starting the car. I suspect it is
due to fuel degradation even though I add Stable to the
petrol. I would like to get a portable jump starter for
extra starting power instead of jumping from my daily
driver. Been checking the list recommendations and some have
a cranking rating but most do not.<o:p></o:p></span></p>
