I always use an inexpensive automatic charger made by Gunsons. Available in
the UK for around 20 from Argos. I use it on all the Gas RC batteries we
sell as well as my own batteries on cars and aircraft. It delivers a high
charge to bring the battery up to charge and then reduces the charge
automatically until it virtually switches off. Far better than a trickle
charge and hardly any more expensive.
