How Often Should I Charge My PV’s Battery to Prolong Its Lifespan? – Weekend Tip

There’s more to just chagrin a battery when it is depleted – they require some maintenance in order for them to continue to function correctly and prolong their lifespan.

Lithium-ion batteries are different from older, nickel-based batteries – charging them incorrectly can decrease their lifespan. Most lithium batteries should last you a few years, but improper care can decrease that lifespan – your battery will be unable to hold a charge, or unable to hold as big a charge as it used to, and take longer to charge.

If you own more than one PV there is a good chance that they don’t all use the same battery type. If you’re not rotating your PV’s often – your batteries aren’t getting the exercise they need to stay strong – a good charge!

Exercise your batteries

Most of us have a few bats we don’t use often and end up sitting on our shelf. There’s nothing wrong with that – but make sure at least once a month you pull them out and give them a shallow charge just to keep the electrolytes going. If they sit to long with no activity they will die a lot quicker.

Shallow Discharges 

Lithium-ion batteries work best when you don’t discharge them to 0%. Battery University recommends that discharges to 50% are better for your battery’s long-term lifespan. This is because 50% discharges provide the best number of cycles-to-usage ratio.

However, that being said most vapers tend to lean towards the 30%-40% discharge – this is when less vapor is produced and flavour can start to decrease – regardless of the voltage.

Some modern MOD’s have on board features that shut your PV down before your battery is at 0% – that’ a cool and useful feature. I know the Lavatube 1.5-T does this.

You don’t have to charge to 100%

Similar to shallow discharges – lithium-ion batteries work best when they  are not fully charged to 100%. You may have heard of the 40%-80% rule – this is a good guideline to follow. Staying within that range can help prolong your batteries lifespan. However, if you do charge it to 100% don’t leave it plugged in to long, most of do this, it can degrade the batteries health quickly. If you are charging over night, which is not recommended, make sure to use a smart charger – a charger that shuts off when the battery reaches it’s capacity.

Don’t overheat your PV

This is pretty obvious – but still needs to be said. Always make sure to keep you batteries cool! Most modern MOD’s have vent holes and other on board features to help prevent batterires from over heating, however it can still happen.

Hopefully these tips will come in handy – remember these are only guidelines and you don’t need to be strict. In the end no matter what we do our batteries will still  die in few years.

  1. Cool article. I see that question asked a lot around the forums. I did my own research and you are right on target! I did not have the information about not charging to 100% though. I will have to check that one out.

    I have 3 batteries I rotate through my Vtube.

    1. Thanks! 🙂 The 100% theory is based in tech – laptops, cameras, etc. We never charge bats 100%. Considering the bats we use on our PV’s are also lithium-ion the same practice can be applied. However, these are just tips.
