Mountain Bike Batteries

mtbbatteries stock a wide range of ready built Li-Ion & NiMH Batteries that are compatible for use with most existing and  obsolete mountain bike lights. Refurbs are also done at mtbbatteries and were possible we will replace your old battery with a new one and use the existing case & lead where possible.


Compatible Batteries we stock: Hope, Exposure, Ay-Up, Lupine, Lumicycle, Troutlights, Magicshine,


We also stock compatible Li-Ion Chargers.


Due to the recent changes in the transportation of hazardous goods mtbbatteries are changing from the Royal Mail to DPD for all the deliveries of our Lights and Batteries.


This way forward will help with the tracking of orders and you will now get an interactive service being able to track the progress of your item on an interactive map.


You will be given a one hour delivery window being notified via text or email. If this is not convenient you can use the text or email to change the delivery date, or choose to ‘deliver to a neighbour’


There will be NO price increase in our products to cover this change.

Li-Ion Batteries

Each Lithium-Ion battery contains a protection circuit that protects against:

Over Charge, Under Discharge, Over Current & Short-Circuit. There is also a resettable fuse fitted inside each cell.


Each battery is supplied at approximately 50% state of charge. This is the best condition for storage. Although the battery can be used straight away we would suggest that the battery is fully charged before use using an appropriate Li-Ion Charger which is also available if required.


Below are 2 typical discharge curves of a 7.5V 4.4Ah & 7.5V 5.2Ah Li-Ion battery as used in the Solarstorm/Magicshine compatible batteries.


The discharge current was set at 2A, which is pretty much the high setting of most Led type lights so this would give a fair time reference of using either battery in your light. 

7.5V 4.4Ah Li-Ion.
Discharge rate set at 2A (typical current when running lights on full)
Start Voltage- 8.4V
End Voltage- 5.6V (set by Protection circuit)
Total run time - 2hrs 9mins 49sec
Tested Capacity- 4.33Ah.

7.5V 5.2Ah Li-Ion.
Discharge rate set at 2A (typical current when running lights on full)
Start Voltage- 8.4V
End Voltage- 5.6V (set by Protection circuit)
Total run time - 2hrs 38mins 39sec
Tested Capacity- 5.29Ah.



The above charts are only to be used as reference notes, as each light and charger used with these batteries would have their own settings to be taken into account for. 

Batteries are also available in a bottle for bottle cages. please email for more details.


We have only shown the most popular batteries that are bought from us. If you cant find the battery or type of connector fitted  you are looking for please email us with the details we will do our best to match it to out existing stock or build a custom specific battery for you.

Just got my Lezyne 1500xxl back from Mark at MTB and it’s Brilliant! Better than original and the service and price was 1st rate.
If your light is running out quick and taking an age to charge it’s likely it needs new batteries.
Give this company a try.
5 stars all the way

Just received my luminator 18 mtb batteries light this time for my handle bars , this combined with the 800 on my helmet is a fantastic light combination .
Can't rate these lights highly enough for price and operation
Stephen B Oct 20
Fantastic product. Ordered online, arrived within days. Great out on the trail and found it to be brighter than my mates lights which were twice as expensive - Luminator 18 bundle.
Sarah T Oct 20
Love my lumen 800, it arrived really soon after ordering. Small, light and great quality. Fits neatly on my helmet and it's my trusty partner on solo nighttime adventures.
Chris N Nov 20
Great service from Mark, got a moon battery re-cell’d that wasn’t holding a long charge. Also ordered the lumen 800 to run alongside my lumenator 18. Very reasonable prices and fast turnaround.

"Great lights came in 4th on the Snowdownhill Gersau 2012, Rigi - Switzerland Team NANDROLON 2RADTUNING says Thank You!!!"


"I bought a set of your lights last week. I used them on a solo non stop ride of the West Highland Way starting on Friday night and they were great. Even on low they were fine for cruising along, so I was easily able to manage the 9 hours of night riding without the battery getting near low. On full power the performance is fantastic, the balance between beam and peripheral seems right to me. It also rained almost non stop and the lights weren't affected at all. The quality of the construction, cables and sealing all look really good and it definitely stood up to the test. Great product at a bargain price.
Best regards,
Tom D"


"Another good service experience here, ordered Tuesday 0950, in my hands at 1030 this morning; well done to both Mr Smudge and Royal Mail! "


"I ordered a V2 XML light off Smudge on sunday and received it today tuesday bloody hell that was quick and he also told me via facebook it was on its way

All the praise heaped on Smudge is well deserved"


“Having 4 friends with your V1 XML light, I finally gave in to the need for more light and was fortunate enough to time it just right with the V2 coming out.
My 'V2' XML Light arrived this morning. Super fast delivery - thanks!
I thought my old light was good but this is an amazing amount of light for the money and seems to be well built and very robust.

Thanks for the great service.


"I really appreciate the stellar customer service. That's really hard to come by these days. I tell everyone I know about those lights, as I think they're absolutely brilliant!"

Cheers, Andy


"Battery arrived the other day and is great. In fact great service and advice throughout, you are definitely my battery source of choice from now on.".
