Alarm system charge currents and backup batteries

[Isetech]

Update - The lithium battery will charge 30% quicker, so in some cases will help. But again it all depends on the load and whether the load is discharging the lithium beyond 80% or even fully discharging.

IF you use a decent 1 C battery you can charge and discharge the lithium battery at the C rating.

For example a 100 amp lithium battery with a 1 C rating can charge at 100 amps, it will be fully charged in 1 hour.

A 100 amp 0.5C lithium battery can generally charge/discharge at 50 amps, it will be fully charged give or take 2 hours.

It is not advisable because it will shorten the life cycles.

The general recommendation is to charge a lithium battery at no more than 30% of it's capacity.

There is no danger of exceeding this with an alarm charger, or gate motor charger.

There are however numerous other reasons why it is not recommended

The reasons ?

They only produce a 0.5 amp trickle charge, which as noted cant improve charge time during load shedding?

The c rating of the battery, using low quality cells?

Reduced life cycles of the batteries maybe?

Batteries installed in application where the battery supplier advertises as "drop in batteries", but the power supply has notice "not to be used with lithium batteries" , this seems to have become a common practise. Thermal scans have identified temperatures exceeding 180 degrees while the lithium batteries screams at a high pitch.

Securi-prod says drop in and sherlo says not advisable.

I can't think of any others off hand.
