I'd charge the igniter at 0.2A. I have a 7hr lead acid as well that I set the start rate at 2A, however, the charge rate will drop as the lead acid gets charged.

For your glow ignitor it depends on how much you use it. If you only race on the weekends then to get the most life out of it you would be best served to completely discharge it after finished with it for the weekend and leave it sitting dead until the day before you need it and charge it back up the day before you need it. If you use it often throughout the week you should get a couple of weeks on a charge. Before charging back up you should discharge it completely before charging back up. You can then charge back up immediately or wait till you need it again.

Either way constantly topping off the nicad battery will create a memory in the battery and greatly shorten the charged life of the unit.

I always charge mine at 1.5 amp but that rate or anything under will be fine.


As for the 12 volt. They are maintenance free with the exception that you do not want to let one of them sit around dead. When the sit dead they have a tendancy to lose the ability to take a charge. They are fine if you run them dead and then charge them right back up but if they go dead the longer you let it sit without a charge in it the greater the chance it won't take a charge. At the end of nitro season I always completely charge mine up before storing them.

That is for Nimh , not Nicad . He stated he has a Nicad .

For Nicads you store them totally discharged and discharge them to 0 when cycling .

I cant believe it but I am with Integra here, discharging a NiCd to 0V is not needed, .9V for NiMh and NiCd... going to 0V is risky and uneeded especially for a glow ignitor.

Nicads build up memory if not discharged all the way , no matter is 6 cell pack or one cell .

0V not needed for a igniter but I was around when every racer dead shorted their nicads with a copper bracelet & I'm pretty sure it was trinity that sold the dead short rings & most of the racers in the world used them. I would make real sure the batt doesnt say nimh on it as many use those for ignitors now. Either way a big mah ignitor will need to be replaced for a worn tip before the cell sees noticable damage if you take even reasonable care of it.
