Don’t mix and match fresh and partially used batteries. Partially used batteries have
lower charges than fresh ones, and lower charges can reduce electrical output.
Fresh and used batteries also have different capacities.
Capacity
is the amount of
energy a battery can deliver in a single discharge (normally expressed in ampere hours).
A difference in capacities can cause a stronger battery to charge a weaker one. A
weaker battery can overheat, fail, leak, vent, catch fire or burst.
•±
Replace all batteries at the same time (except for memory-hold batteries). They should
be fully charged. This is so you don’t mix new and old batteries, creating a difference in
capacities. That’s a straight path to overheating, leaking and the other battery problems
described earlier.
•±
Use batteries from the same manufacturer. Make sure the batteries have a date code
within 6 months of one another. Remember, not all batteries are equal—even if they
look alike. Storing batteries in their original packaging helps to identify them.
Batteries from different manufacturers may have different chemical properties. That
can lead to a difference in capacities and—well, you know the sad story.
•±
If you don’t plan to use your commo gear for 30 days or longer, take out the batteries and
store them according to your SOP. That removes the risk of battery corrosion damage.
