What happens if you charge a rechargeable battery in parallel?

for secondary (rechargeable) batteries – the stronger battery would charge the weaker one, draining itself and wasting energy. If you connect rechargeable batteries in parallel and one is discharged while the others are charged – the charged batteries will attempt to charge the discharged battery.

Can a rechargeable battery recharge to the same level?

Even rechargeable batteries will not recharge to the same level as new ones. As such, the following guidelines are important: With primary (disposable) batteries – only use batteries of the same brand and age (ideally from the same packet). If this isn’t possible, double check the voltages of each unit with a voltmeter.

Can batteries of different voltages be connected in parallel?

It’s worth pointing out that many people accidentally connect batteries of different voltages in parallel every day. For example: If you mix brands even of the same labelled voltage – you can experience problems. Due to different manufacturing processes, the exact voltages of batteries from different producers can vary slightly.
