Why 1992 Olds 88 Royale 3.8L starts fine for 5 days then day 6 turns over fine but won't start then back fires Day 7 I charged batteries Day 8-12 Car started like normal day 13 same as day 6?
While I am no means an expert. I would say check your coil Packs & the ignition starter which is located under the coil packs. There are 3 coil packs. Or your crank sensor could be going. If you notice your car stalling out even on short trips & not wanting to start back up, till the car cools off. I would say crank sensor. I have had to replace all of these things in my car, plus a water pump.
Unless you want to see batteries burst, you should never charge normal alkaline batteries with any charger. Brand names don't matter much in this sense either. Only charge batteries that have the word "Rechargeable" or "NiMH" on them. Though there are some alkaline batteries that are rechargeable, a regular battery faces the risk of explosion or severe damage when charged.
If I understand the type of light you seem to be referring to correctly, the answer is no you need rechargeable AA batteries (e.g. NiMH). Normal AA batteries (e.g. alkaline, heavy duty) are not rechargeable and can be damaged or even explode if it is attempted to recharge them. Use only the type of batteries the instructions for such devices specify.
