I've a gas fire that uses a Lithium battery Saft 2LSH20 for ignition.

These come in at about an eye watering £40 each and last less than a
year.

I replaced it with 5 1.5V alkaline cells which are considerably cheaper
but seem to last about the same time. There is still a considerable
charge in the cells - 4A into a S/C.

My questions are :-

1) Why don't they last ? Does it draw current all the time, or only
during ignition or while the fire is on? Is there a minimum voltage ?

The site says

"it depends on how often the unit is operated and how often it is left
on."

2) Is there something better ?

Does seem strange. After all if you can use normal batteries why up the cost
of building it by including an expensive battery that does not recharge, or
is it that its supposed to but won't.

Are they easy to change? If so get two sets of re-chargeables. They will
need changing more frequently, but save money.
