Just a few pictures of what we can offer at MTBBatteries with light & battery repairs and re-celling. 

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’


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.
