General Questions

Can I change or cancel my order once it’s been placed?

Processing starts almost immediately so unfortunately, once an order has been placed, it can’t be changed. For the same reason, it’s not usually possible for us to cancel an order once we’ve received it.

If you have changed your mind and would like a refund on your Badaptor order once it’s delivered, simply email our sales team within 30 days.

Are Badaptors compatible with the full range of another tool brand?

Each model in the Badaptor range is designed to be compatible with the full range of the designated brand of tools. Depending on the model, you can use a Badaptor to convert your 18V battery to work with DeWalt, Makita, Milwaukee or Ryobi tools.

Can I charge my battery using the Badaptor?

You should only use a Badaptor to convert your 18V batteries to work with another brand of tool.

The Badaptors aren’t designed for charging your existing battery in another manufacturer’s charger, and it’s not safe to do so.

Is the Bosch Badaptor compatible with all Bosch 18V batteries?

The Bosch Badaptor is designed to work with the range of Bosch Professional and Procore 18V batteries only. Unfortunately, it isn’t compatible with any other sub-brand of Bosch battery.

What happens if something is wrong with my Badaptor when it arrives?

All Badaptors are covered by a one-year warranty against faulty manufacture. If you’ve received your Badaptor, and it doesn’t work, just email our sales team and we’ll send you a  refund or a replacement product.

When sending a Badaptor back to us, please be aware that we’re unable to accept any responsibility for any further damage or loss that may occur in transit. For this reason, please make sure it is properly packed before sending it back to us.

Can I return my order for refund or exchange?

If you change your mind, you can return your Badaptor to us in its original, unused condition within 30 days for a full refund. Just email our sales team before returning your item, so they can start the process.

When sending a Badaptor back to us, please be aware that we’re unable to accept responsibility for any further damage or loss that may occur in transit. For this reason, please make sure it is properly packed before sending it back to us.

If the returned item is found to be damaged or requires repackaging, these costs will be deducted from any refund.

What if my Badaptor is damaged or lost in transit?

If you take delivery of your order and find that it’s been damaged in transit, or that part of your order is missing, let us know as soon as possible (no later than 2 working days after receipt).

Once you’ve notified our sales team, damaged Badaptors can be returned to us within 30 calendar days for a refund or exchange.

If anything is missing from your order, or it hasn’t been delivered, let us know within 14 days of your invoice date, and we’ll get back to you as soon as we can.

Will I be charged any customs charges or import taxes?

If you are ordering a Badaptor from outside the UK, you may incur a charge for importing an item from abroad. We are not liable for any costs incurred, and it is your responsibility to pay these charges.

More information on import fees may be available from your local customs office.

Safety & Usage

Can using a Badaptor shorten the life of my battery?

Normally, no.

Most tools and many types of battery contain protection to stop the batteries discharging below the point where they can no longer be recharged.

It is this protection that simply stops the tool when the battery needs recharging. Tool/battery combinations without protection just get slower and slower as the battery voltage drops.

However, as tools and batteries are changing all the time, we are aware of some combinations where neither the tool nor battery has deep discharge (also known as over-discharge) protection. In these cases, if the tool continues to be operated as it starts to slow down considerably, it’s possible to drain the battery to a point where it could not be recharged again.

It is good practice to recharge Lithium-Ion batteries before they get too low as this puts less strain on the battery and tool and will extend the life of both.

So, as long as the user exercises good judgement, the Badaptors are safe and convenient to use. 

Can I use the Badaptor to charge my battery using a different manufacturer’s charger?

No, the Badaptor does not allow you to do this and will not allow charging to take place.

Why do Lithium-ion batteries age?

A combination of charge cycles and elevated temperatures will gradually decrease the performance of lithium-ion batteries over time. Typically manufacturers claim 300-500 discharge / charge cycles as the battery life. But this can be affected by heavy use that draws high current, deep drain and temperature conditions.

It is reasonable to expect batteries to provide 100% capacity during the first 12 months service.

How do I maximise Lithium-Ion battery life?

Discharging and charging puts a strain on the battery and deeply discharged batteries are strained more during recharging. Heavy current loads and the associated fast discharging also strain the battery. Lithium-ion batteries will last longer if they are charged when only partially discharged, rather than allowing it to fully discharge before recharging. The sweet spot for recharging is around 50%

How is it best to store Lithium-ion batteries?

Manufacturers recommend storage at 15°C with a 40-50% charge to maximise battery life.

When looking at battery storage, two things need to be considered.

Storing batteries fully charged at high temperatures above 30°C can potentially damage the battery.

Storing batteries with a very low charge means they will self-discharge below the critical minimum voltage sooner and then be impossible to recharge.

How quickly does the charge decay during storage?

Lithium-ion batteries lose their charge (self discharge) more slowly than other types of batteries such as Ni-Cad and NiMH. At normal ambient temperatures of 20°C Lithium-ion batteries self discharge around 5% in the first 4 hours after charging and then at around 1-2% per month.

Does ambient temperature affect battery life?

Optimum usage temperature is 15-20°C, cycle life is reduced by 20% at 40°C.

Lithium-ion batteries are stressed more when kept above 30°C. Storing batteries fully charged in high elevated temperatures can reduce battery life quicker than normal discharge / re-charge cycling.

Low temperatures reduce the battery capacity as the internal resistance is increased. A temperature of -18°C would reduce the battery capacity to 50%

Continued use of batteries in both high and low ambient temperature environments will accelerate their capacity decay.

Does the Badaptor contain a safety system to stop my battery being used past the point of recharge?

There is no in-built cut-off system in the Badaptor – it’s simply a battery adapter that allows customers to use their 18-20V batteries with another brand of power tool.

All current generation batteries that work with Badaptor contain over-discharge protection. This means the battery will automatically switch off once the power reaches a level that could cause long-lasting damage.

When using Lithium-ion batteries, they should never be drained completely as this can cause damage and prevent them from working. With an 18/20V system, the batteries should not be discharged below 14V.

With most tools, when the battery voltage drops to around 16V, the tool’s speed and performance start to fall off. At 15-14V the drop in performance is severe and it is obvious that the battery needs recharging.

We would recommend the batteries be recharged when the performance starts to fall off as this will extend battery life, and maximise overall tool life.

To protect your battery, do not continue to operate if the tool performance has noticeably reduced.

What happens if I discharge my battery too deeply?

Lithium-ion batteries should not be discharged below a certain voltage. Doing so will mean they cannot be re-charged with a normal charger. Some manufacturers’ batteries have circuits in them to prevent over discharging, and other manufacturers put circuits in their tools to prevent over discharge.

The main problem occurs when batteries are stored at low levels of charge and/or low temperatures. The charge decays over time putting the battery voltage below the point at which it can be recharged.
