Can throw away batteries be charged?

[ShawnD]

I have 4 of those big 6V batteries used mostly in flashlights. The batteries are almost dead and I really don't want to break the bank buying new ones. Can I just hook them up to my 9V battery charger (in parallel) and charge them? Will they hold a charge again? Will they explode?

Nope. Sorry, but it won't work. If it did, why would people pay more for rechargable batteries? What you'd need is a device called a pulse recharger, which can recharge regular batteries as if they were rechargeables. Of course, even with this you'll get lower amounts of charge stored, and the batteries will allow for far less recharges than ones designed to be recharged.

No, throw away batteries cannot be charged. These types of batteries are typically alkaline or zinc-carbon batteries, which are not designed to be recharged. Attempting to charge them can be dangerous and may cause them to explode or leak hazardous chemicals.

It is also not recommended to mix different types or voltages of batteries in a charger, as this can cause damage to the batteries or the charger itself.

If you are looking to save money on new batteries, consider investing in rechargeable batteries and a compatible charger. This will not only save you money in the long run, but also help reduce waste and protect the environment.
