Battery Will Not Charge

[walk10]

Hi
I have a constant battery warning on my keypad and I have tested my battery and it is very low.  I bought a new battery and very soon had the same problem.  
When looking closely at the LP51 and LP52 bulbs they appear to have blown.
Is it possible to get replacement bulbs?  I am able to solder them on if I could get new ones.
Any help is much appreciated.
Thanks
Dave

Replace the bulb with a Resetable fuse, You can buy from Farnell

Just solder it to one of the LP51 or LP52 as they are in parallel
This will protect the battery from overcharging but will not burn up
