1.   Is the M29 accurate? The M29 is very accurate, the battery is fully
     discharged during the test to prove the performance.
                                                                                      ASTRATEC M29 AUTOMATIC
                                                                                   BATTERY PERFORMANCE CHECKER
2.   Does the battery need to be fully charged? Yes it does, the M29
     will tell you if the battery is not charged.
3.   Can I test any battery with this tester? Yes any 12 volt lead acid
     (including AGM and GEL types) in the range 10-100 Ah can be tested,
     including unknown far eastern brands.                                                *Easy to use, no technical knowledge required!
4.   Will manufacturers understand and accept these results? Astratec
     have been producing battery testers for more than 25 years, our
     products are well known to battery manufacturers and we can provide
     technical support as needed.

♦ Lead acid batteries should not be left for long periods in a discharged
     state - recharge your battery as soon as you can after use. This will
     extend its life.
♦ If during the winter you do not use your battery, charge it up for a day
     every month, this will keep it in good condition.
♦ Don’t leave your battery on charge all winter (unless your charger
     instructions says this is OK).
♦ Once fully charged, batteries self discharge very slowly and can be left
     for a month or so without any need to top them up.
♦ Keep the battery cool, don’t place in bright sunshine or next to a boiler,
     this may reduce the life of your battery.
