Check battery voltage using Volt meter=> it should be about 12.6 to 13.8 vdc.
Pull the battery out... checking the deforming at the case ..such as "swelling"... if yes .. replace the battery.
Replacement battery is about 10-20 dollars on e-bay (watch for shipping charge and size. and terminal connection sizes )
The average life of battery on UPS is about 5-7-10 years wi)th UPS plugged in (Charging
One I had my local Autozone checked my 12 VDC -8 AH ... ask them to set CCA at about 100 AMP...
for 12 VDC -14 AH ask them to set CCA about 200 AMP.
For a 12 VDC -75 AH (group 24) they set the load on their tester at about 700-900 CCA.
You can also buy a manual battery load test at Harror freigt tool for about $20 US dollars (On sale)

if it has a battery that can be replaced then i would take it to like a battery express or a battery plus store. Where they can attempt to open the unit and size out the battery. As online i cant find any information about the unit. If you know the battery size i can help you price it out online. It says its a Rechargeable 300 mAh Lithium-Ion Polymer battery that is easily changeable.
if thats the case add an additional comment with the battery size and i will find it online for you to be able to order. i will be here to assist you. If this assisted you please feel free to rate the comment. thanks and have a great day.

You can buy new batteries and buy the one it says to buy on the package.

A typewritter is not like a computer. It is a mechanical device, that works by pressing an embossed letter in the daisy wheel through a inked tape into the paper.
The only way you can change either the font type or the font size is by buying and replacing the daisy wheel by another one with different font type/size letters.
To get to know more about your typewritter and accessories that might still be available to it, download Brother ML-100 Typewriter User's Manual
Click on "Go to View/Download Page" and in the new page click the "View/Download" button.
Look for page 16 (last page) of the manual for a list of cassette daisy wheels.

your cars battery might only need charging or battery acid replacement, but if you'd realy wish to buy new one, buy one with the same size and voltage and amps as the one you have right now, or you could buy a battery with the same voltage with a higher amppere-hour (Ah) rating!
