Question Can I use a lower volt / wH battery in my laptop?

[O0mix0O]

Hey all,

Can I replace my 7.6V / 62Wh battery with a 7.4V / 51Wh battery? (and also still use the same 63W charger?)

If interested:

• Dell Latitude E5470
• Both batteries seem to be the same size (+ seen 7.6V laptop models in 7.4V listings)
• I'm aware there will be a drop in battery life - That's fine
• A decent 7.6V battery is 3x the price of the 7.4V and I don't want to be spending that
• Example 7.4V / 7.6V

Thanks in advance!

7.4 or 7.6 won´t be an issue

be careful using these batteries, don´t charge your laptop without you in the same room. Some might not be protected against overcharge/overheating and can be dangerous.

The question I'd like to ask you is, what are the specs of the original battery for your laptop? You should get a replacement that is either genuine or identical to the original battery. Not 3 items the price but is less than that.

My experience of 3rd party laptop batteries is they are a waste of money. They either don’t work or they use cheap cells that die very quickly. Just pay the extra and get a genuine Dell replacement.

Cheaper batteries are cheaper for a reason. If you value your laptop steer clear of them, especially on fleabay.

I'm starting to see a trend here... 😂

So a lower V battery would be fine, just be sure to buy genuine!

If you buy a genuine OEM replacement it will have the same power specs as the original. That's the only one I would buy, but I fully understand not everyone can afford to do that.

But don't assume that a lower voltage battery will be ok. The only choice for me would be where to get it from, not whether I should get one with different specs.

Yeah completely, I do follow the mantra "buy cheap, buy twice" but unfortunately money has been dictating things recently!

Yeah very fair point - I know it's fleabay, but based on the feedback for this specific battery, that it's listed as genuine, and the seller's 40k/100% score, I've gone for this one.

Thanks everyone for your quick and sobering replies!
